Figure 1-5 shows the ODU principles.
Figure 1-5 Working principles of the ODU
The ODU is located between the IDU and the antenna system, implementing the functions of
frequency conversion and amplification of signals. The working principles of the ODU are as
follows:
l Processing of the signals to be transmitted
The multiplexer unit divides the input signals transmitted through the IF cable into the IF
TX signals, O&M uplink signals, and -48 V DC power signals.
The IF TX signals are processed as follows:
a. The IF TX signals are up-converted, filtered, and amplified to RF TX signals. Then,
the RF TX signals are sent to the AMP unit.
b. The AMP unit amplifies the power of the RF TX signals. The power of the RF TX
signals can be controlled by the IDU software.
c. The amplified RF TX signals are sent to the antenna through the duplexer isolation
unit.

RTN XMC ODU
The O&M uplink signals are the 5.5 MHz signals modulated in Amplitude Shift Keying
(ASK) mode. The signals are sent to the CTRL unit and demodulated.
The -48 V DC power signals are sent to the PWR unit. The PWR generates secondary
power supplies for each module of the ODU.
l Processing of the received signals
a. The duplexer isolation unit separates the RF input signals from other signals
received by the antenna.
b. The RF signals are amplified through the Low Noise Amplifier (LNA) unit.
c. The amplified RF signals are down-converted, filtered, and amplified to IF RX
signals and transmitted to the multiplexer unit.
d. The multiplexer unit combines the IF RX signals and O&M downlink signals and
then transmits the combined signals to the IDU through IF cable.
The CTRL unit performs the ASK modulation on the O&M downlink signals to generate
10 MHz signals. The modulated signals are transmitted to the multiplexer unit. The
CTRL unit provides the RSSI interface and monitors the RX level through the RSSI
circuit.
1.5 Installation Mode

The ODU can be installed on the antenna in two modes: direct mounting mode and separate
mounting mode.
NOTICE
The ODU does not support hot swapping.
Direct Mounting Mode

When the small-diameter and single-polarized antenna is used, the direct mounting mode is
usually adopted. In this case, if one ODU uses one antenna, the ODU should be installed at
the back of the antenna. If two ODUs share one antenna, one RF signal combiner-divider
(hereinafter referred to as hybrid coupler) should be added between the antenna and the ODU.
Use a hybrid coupler adaptive to the XMC ODU if two ODUs are configured with only one antenna installed
in direct mounting mode.
If a single XMC-5D ODU is installed on an antenna in direct mounting mode, a hybrid coupler or an OMT
must be configured.
Figure 1-6 shows the direct mounting mode. In this document, XMC-3/XMC-3W/XMC-3H
ODU is used as an example.

RTN XMC ODU
Figure 1-6 Direct mounting mode
Separate Mounting Mode

When the dual-polarized antenna or the large-diameter and single-polarized antenna is used,
the separate mounting mode is adopted. In this case, two ODUs can share one feed boom by
adding a hybrid coupler.
In separate mounting mode, the ODU separated mounting bracket is used to fix the ODU or
hybrid coupler on the pole. The ODU or hybrid coupler and the antenna are connected
through a flexible wave guide.
If a single XMC-5D ODU is installed in split mounting mode, a flexible waveguide adapter and an
XMC-5D split mounting bracket must be configured.
Figure 1-7 shows the split mounting of a single-polarized antenna. In this document, XMC-3/
XMC-3W/XMC-3H ODU is used as an example.

Frequency Information
l Instead of the upper/lower limits of the central frequency of channels, the upper/lower limits of the
frequency that carries the TX signals are described as follows to indicate the scope of frequencies
supported by the ODU. The lowest central frequency of channels is higher than the lower limit
frequency by half of the channel spacing. The highest central frequency of channels is lower than the
upper limit frequency by half of the channel spacing.
l The T/R spacing values listed in the following tables are default values. In special application
scenarios and within the frequency range covered by the duplexer, the T/R spacing values within
each band are configurable.
Table 1-18 lists the information about the 6 GHz frequency band.

NOTE
l The channel spacings supported by XMC-3 ODU complies with the ETSI standard. In the ETSI
standard, the 18 GHz frequency band is planned based on the interval of 13.75/27.5/55 MHz, which
corresponds to 14/28/56 MHz in most application scenarios.
l The 3.5 MHz bandwidth can be implemented only when the IS3 mode of the intermediate frequency
(IF) board is supports the modulation mode of QPSK and 16 QAM.
l The 112 MHz bandwidth can be implemented only when the IS6/IS8 mode of the intermediate
frequency (IF) board is used in the 32 GHz working frequencies;The 112 MHz bandwidth supports

10 MHz, 20 MHz, 30 MHz, 40 MHz, 50MHz (FCC)
NOTE
l The channel spacings supported by XMC-3W ODU complies with the ETSI standard. In the ETSI
standard, the 18 GHz frequency band is planned based on the interval of 13.75 MHz, 27.5 MHz and
55 MHz, which corresponds to 14 MHz, 28 MHz and 56 MHz in most application scenarios.
(IF) board is supports the modulation mode of QPSK and 16 QAM.
l The 4096 QAM can be implemented only when the IS6 mode of the intermediate frequency (IF)
board is used and under the normal temperature condition; 4096 QAM supports only Channel
spacing is 28 MHz, 40 MHz and 56 MHz; 4096QAM is supported only when the AM function is
supported. ATPC is not supported.
l The cable length requirements for the 4096 QAM in the 7 GHz, 8 GHz, 13 GHz, 15GHz, 18 GHz,
23GHz working frequencies are as follows: If the Channel spacing is 40 MHz or 56 MHz, the cable
length must be less than 30 m or greater than 80 m.
l The XMC-3W ODU supports channel spacings that comply with the FCC standard when working at
the 15 GHz frequency band. In addition, only the ISM6/CSHR board provides this support working
in IS3 mode.

RTN XMC ODU
Item Specification
NOTE
l The channel spacings supported by XMC-3H ODU comply with the ETSI standard. In the ETSI
standard, the 18 GHz frequency band is planned based on the interval of 13.75 MHz, 27.5 MHz, 55
MHz and 110 MHz, which corresponds to 14 MHz, 28 MHz, 56 MHz and 112 MHz in most
(IF) board supports the modulation mode of QPSK and 16 QAM.
l The 112 MHz bandwidth can be implemented only when the IF board works in IS6 mode or IS8
mode at the 18 GHz, 23GHz, 28 GHz or 38 GHz working frequency.
l When the IF board works in IS6 mode at the 15 GHz, 18 GHz or 23 GHz working frequency,
mapping between the channel spacing and supported highest modulation mode is as follows: 7 MHz
– 1024QAM; 14 MHz – 2048QAM; 28 MHz to 56 MHz – 4096QAM; 112 MHz – 2048QAM.
Both 4096QAM and 2048QAM support only the AM and do not support the ATPC.
l When the IF board works in IS6 mode at the 28 GHz or 38 GHz working frequency, mapping
between the channel spacing and supported highest modulation mode is as follows: 7 MHz –
1024QAM; 14 MHz to 112 MHz – 2048QAM. The 2048QAM supports only the AM and does not
support the ATPC.
l When the IF board works in IS8 mode at the 15 GHz, 18 GHz, 23 GHz, 28 GHz or 38 GHz working
frequency, mapping between the channel spacing and supported highest modulation mode is as
follows: 7 MHz – 1024QAM, the 1024QAM@23GHz supports only the AM and do not support
the ATPC; 14 MHz – 2048QAM, the 2048QAM supports only the AM and do not support the
ATPC; 28 MHz to 56 MHz – 8192QAM, the 4096QAM and 8192QAM support only the AM and
do not support the ATPC; 112 MHz – 4096QAM, the 4096QAM supports only the AM and do not
support the ATPC.
l A 4096QAM cable used by an extended ISM6 board works in IS6 mode must be shorter than 30 m
or longer than 80 m when the channel spacing is 40 MHz or 56 MHz.
or longer than 60 m when the channel spacing is 112 MHz.

NOTE
l The channel spacings supported by XMC-5D ODU comply with the ETSI standard. In the ETSI
standard, the 18 GHz frequency band is planned based on the interval of 13.75 MHz, 27.5 MHz, 55
MHz and 110 MHz, which corresponds to 14 MHz, 28 MHz, 56 MHz and 112 MHz in most
l When CA is configured for the XMC-5D ODU, the same bandwidth, modulation format, and
transmit power must be configured for the sub-carriers of a single-channel CA. Only the
14/28/40/56 MHz at 13/15 GHz support CA.
l Non-CA configuration: In IS3 mode at 13/15 GHz frequency band, when the channel spacing is 7
MHz, the maximum modulation format is 256QAM. When the channel spacing is 14 MHz, the
maximum modulation format is 1024QAM Light. When the channel spacing is between 28 MHz
and 56 MHz, the maximum modulation format is 2048QAM.
Non-CA configuration: In IS6 mode at 13/15 GHz frequency band, when the channel spacing is 7
maximum modulation format is 2048QAM. When the channel spacing is between 28 MHz and 56
MHz, the maximum modulation format is 4096QAM. The 4096QAM supports only the AM
function, but does not support the ATPC function.
Non-CA configuration: In IS8 mode at 13/15 GHz frequency band, when the channel spacing is 7
l Non-CA configuration: In IS3 mode at 18 GHz frequency band, when the channel spacing is 7
maximum modulation format is 1024QAM Light. When the channel spacing is between 28 MHz
and 56 MHz, the maximum modulation format is 2048QAM.
Non-CA configuration: In IS6 mode at 18 GHz frequency band, when the channel spacing is 7
Non-CA configuration: In IS8 mode at 18 GHz frequency band, when the channel spacing is 7
MHz, the maximum modulation format is 256QAM. When the channel spacing is 14/28/40/56/112
l CA configuration: In IS8 mode, when the channel spacing is 14/28/40/56 MHz, the maximum
modulation format is 2048QAM. The 2048QAM supports only the AM function, but does not
support the ATPC function.
or longer than 80 m when the channel spacing is 40 MHz or 56 MHz.

2.1 Device Type

The hybrid couplers is available in two series: balanced hybrid coupler and unbalanced hybrid
coupler.
Hybrid couplers are classified based on the attenuation values of tributary signals. The
attenuation values are the same in the transmit and receive directions. The differences
between the two types of hybrid coupler are as follows:

RTN XMC ODU
l A balanced hybrid coupler is also called a 3 dB hybrid coupler.

The 3 dB hybrid coupler divides one channel of RF signals into two channels of RF
signals of the similar power. The power of each divided channel of RF signals is
approximately 50% of the original channel of RF signals. That is, the power attenuation
value of each divided channel of RF signals is approximately 3 dB, as compared with the
original channel of RF signals.
l An unbalanced hybrid coupler is also called a 6 dB hybrid coupler.
The 6 dB hybrid coupler divides one channel of RF signals into two channels of RF
signals of different power. The power of the channel of extension tributary signals is
approximately 25% of the original channel of RF signals. That is, the power attenuation
value of the channel of extension tributary signals is approximately 6 dB, as compared
with the original channel of RF signals. The power of the channel of main tributary
signals is approximately 75% of the original channel of RF signals. That is, the power
attenuation value of the channel of main tributary signals is approximately 1.5 dB, as
compared with the original channel of RF signals.

4.2 Functions
A dual coupler provides the coupler function for two independent channels. For each channel,
the two channels of RF signals are combined and divided between two XMC-5D ODUs.
The functions and features of dual couplers are as follows (assume that the two XMC-5D
ODUs are ODU A and ODU B):
l In the transmit direction, the RF signal of the RF1 port of ODU A and the RF signal of
the RF1 port of ODU B are combined into one channel of RF signals. At the same time,
the RF signal of the RF2 port of ODU A and the RF signal of the RF2 port of ODU B are
combined into one channel of RF signals. The two channels of signals need to be
combined or adapted and then transmitted to the antenna through a flange adapter, a flat
coupler, or a flat OMT.

RTN XMC ODU
l In the receive direction, after the RF signals received from the antenna are adapted or
divided by the flange adapter, flat coupler, or flat OMT, the dual coupler divides these
signals into four channels of RF signals and transmits them to the ODUs.

The dual coupler is mainly composed of two waveguide cavities.
The waveguide cavity is the main component of the dual coupler. It has three interfaces:
common interface, main tributary interface, and extension tributary interface.
The working principles of one waveguide cavitie on the dual coupler are as follows:
l In the TX direction, the RF signals received from the main tributary interface and
extension tributary interface are combined into one route in the waveguide cavity and
transmitted from the common interface.

5 OMT (Single-channel ODU)
The orthogonal mode transducer (OMT) is the short name for the polarized hybrid coupler.
The OMT is used when two ODUs with different polarization directions need to be installed
on the same antenna.
The OMT must be used by UHP S2D Antenna.
5.1 Functions and Features

The OMT separates V polarization from H polarization for RF signals.
5.2 Working Principle

RTN XMC ODU
l In the transmit direction, the OMT performs conversion between a rectangular

waveguide cavity and a round waveguide cavity, so that V/H-polarized waves separately
from two rectangular waveguide cavities can be transmitted in the round waveguide
cavity and then sent to free space by means of an antenna with a round waveguide
interface.
l In the receive direction, the OMT receives V/H-polarized waves from the round
waveguide interface of an antenna, separates V-polarized waves from H-polarized
waves, and transmits the separated waves to appropriate rectangular waveguide cavities.
5.3 Interfaces
The OMT has three types of interfaces: antenna interface, V-polarized ODU interface, and H-
polarized ODU interface.
l The antenna interface of the OMT is a round recessed waveguide interface.

Hardware Description 10 Antennas
10 Antennas
The microwave device uses the parabolic antennas to transmit and receive electromagnetic
waves. The antennas described in this document are the parabolic antennas adaptive to the
RTN XMC ODUs.
10.1 Device Type

Antennas are classified into two types, namely, the single-polarized antenna and dual-
polarized antenna.
10.2 Functions
The microwave antenna is used to convert between the RF signals transmitted from the ODU
and electromagnetic waves radiated in the air.
The antenna consists of the reflector, feed boom, radome, shield, and mounting bracket.
10.4 Interfaces
The feed boom interface of the single-polarized antenna in direct mounting mode is a
waveguide interface. The feed boom interfaces of the single-polarized antenna in separate
mounting mode and of the dual-polarized antenna are flange interfaces.
10.5 Antenna Diameters
The antenna diameters vary according to the antenna type and the frequency band where the
antenna operates.
The technical specifications of the antenna include the electrical indexes and mechanical
indexes. The electrical indexes of the antenna include the antenna gain, half-power
beamwidth, VSWR, and front-to-back ratio. The mechanical indexes of the antenna include
the size, weight, wind-protective feature, and ice/snow-protective feature.
10.1 Device Type

Antennas are classified into two types, namely, the single-polarized antenna and dual-
polarized antenna.
In addition to simple single-polarization and dual-polarization antennas, there are some
special antennas:

RTN XMC ODU
The UHP S2D antenna is a multifunctional antenna that converts the default single polarized
antenna into a bipolar antenna by modification.
The UHP SDB antenna is a dual-frequency antenna that transmits both traditional band and E-
band signals at the same time. Each frequency band can be single-polarization or dual-
polarization.
The UHP modular antenna is a new type of combinatorial antenna. It can be switched from
traditional band to E-band or from a traditional frequency to another by replacing the feed.
The antenna can be switched between single-polarized antenna and dual-polarized antenna by
replacing parts.
10.1.1 Single-polarized antenna

The single-polarized antenna transmits or receives electromagnetic waves in a specific
polarization direction. The single-polarized antenna provides a feed boom interface. The feed
boom interface can be set to be vertically polarized or horizontally polarized.
According to the mode of installing the ODU on the antenna, the single-polarized antenna is
classified into two types, namely, the direct mounting mode and separate mounting mode. The
single-polarized antenna with the diameter less than or equal to 1.8 m supports the direct
mounting mode and separate mounting mode. The single-polarized antenna with the diameter
greater than 1.8 m supports the separate mounting mode.
Figure 10-1 and Figure 10-2 show the feed booms of the single-polarized antennas.
Figure 10-1 Feed boom of the single-polarized antenna with the diameter less than or equal to
1.8 m

10.1.2 Dual-polarized antenna

The dual-polarized antenna transmits and receives horizontally-polarized and vertically-
polarized electromagnetic waves at the same time. According to the mode of installing the
ODU to the antenna, the dual-polarized antenna is classified into two types, namely, direct-
mount antenna and separate-mount antenna.
Figure 10-3 and Figure 10-4 show the feed booms of the separate-mount dual-polarized
antenna and the direct-mount dual-polarized antenna.
Figure 10-3 Feed boom of the separate-mount dual-polarized antenna

Figure 10-4 Feed boom of the direct-mount dual-polarized antenna
10.1.3 UHP S2D antenna

The UHP S2D antenna is a multi-function antenna. It has the following functions:
l A single-polarized antenna is used by default, which can be transformed to a dual-
polarized antenna installed in direct-mounting mode.
l If a single-polarized antenna is transformed to a dual-polarized antenna, the OMT or
dual-polarized combiner can be used to allow multiple ODUs to be installed in direct-
mounting mode. In this way, the configuration of XPIC/1+1 or ACAP/CCDP 4+0 can be
achieved.
10.1.4 UHP SDB antenna

UHP SDB antennas are dual-band antennas. One antenna can transmit both common-
frequency-band and E-band signals. These antennas have the following functions:
l This type of microwave antennas provides both horizontal and vertical polarization. The
antennas are vertically polarized by default in factory settings. Customers can change the
polarization state as required.
l The antennas support both single polarization and dual polarization on common
frequency bands, and support both single polarization and dual polarization on the
Eband.
l Suggestions on antenna alignment: Align antennas for common frequency bands, and
then for the E-band.
There are two kinds of UHP SDB antennas. Figure 10-5 and Figure 10-6 show the
appearance of antennas.

The UHP modular antenna is a new-generation combination antenna. The components of this
antenna can be split. The functions are as follows:
l This antenna provides two types of antennas: Class 3 and Class 4.
l With the addition of an OMT, single-polarized antennas can be changed to dual-
polarized antennas.
l With the replacement of an antenna feed, the antenna may be used in different frequency
bands, including the common frequency band (6 GHz ~ 42 GHz) and the E-band

Figure 10-7 Appearance of the UHP modular antenna
10.2 Functions
The microwave antenna is used to convert between the RF signals transmitted from the ODU
and electromagnetic waves radiated in the air.

RTN XMC ODU
l In the TX direction, the antenna converts the RF signals transmitted from the ODU into
directional electromagnetic waves and then radiates electromagnetic waves in the air.
l In the RX direction, the antenna receives and assembles electromagnetic waves from the
air, converts electromagnetic waves into the RF signals, and then transmits the RF
signals to the ODU.

The antenna consists of the reflector, feed boom, radome, shield, and mounting bracket.
Figure 10-8 shows the structure of the antenna.
This section takes the single-polarized antenna as an example to describe the working principles of
antennas. The dual-polarized antenna has two feed boom interfaces and thus can transmit and receive
electromagnetic waves in the vertical and horizontal polarization directions at the same time. The
working principles of each component of the dual-polarized antenna are similar to the working
principles of each component of the single-polarized antenna.
Figure 10-8 Structure of the antenna
1. Feed boom 2. Reflector 3. Shield
4. Radome 5. Mounting bracket -
The functions of each component of the antenna are described as follows:

l Feed boom
The input interface of the feed boom receives the RF signals transmitted from the ODU.
The received RF signals are transmitted through the waveguide to the output interface of
the feed boom, which is located at the focal spot of the reflector. The output interface of
the feed boom is equivalent to a preliminary horn antenna. It radiates electromagnetic
waves towards the antenna reflector.

RTN XMC ODU
You can change the polarization direction of the antenna by rotating the feed boom. The
polarization direction of the antenna is the polarization of electromagnetic waves
radiated by the antenna. The polarization direction of electromagnetic waves is the
direction of the electrical field. Figure 10-9 shows the polarization directions supported
by the rectangular waveguide.
The polarization direction of the antenna must be the same as the polarization direction of the
ODU or hybrid coupler. The feed booms of certain types use the round waveguide. In this case,
see installation instructions of the antenna to adjust the polarization direction of the antenna
according to the polarization identifier.
Figure 10-9 Polarization directions supported by the rectangular waveguide
l Reflector
Normally, the reflector of the microwave antenna is a rotatable paraboloid. The reflector
is mainly used for reflecting electromagnetic waves and providing the directive gain.
– In the TX direction, the reflector reflects electromagnetic waves radiated from the
feed boom so that electromagnetic waves are directional.
– In the RX direction, the reflector reflects electromagnetic waves received from a
wider space, and then assembles electromagnetic waves to the output interface of
the feed boom.
l Radome
The radome protects the antenna from damages caused by the wind, rain, and ice.
Electromagnetic waves can be radiated through the radome.
l Shield
The shield is installed on the HP antenna. The shield is mainly used for suppressing the
radiation of the side lobes.
l Mounting bracket
The mounting bracket is used for fixing the antenna onto the pole and for adjusting the
azimuth and elevation slightly. In addition to the mounting bracket, a reinforcing rod is
required for fixing the antenna with a larger diameter. For details, see the instructions for
the antenna.
10.4 Interfaces
The feed boom interface of the single-polarized antenna in direct mounting mode is a
waveguide interface. The feed boom interfaces of the single-polarized antenna in separate
mounting mode and of the dual-polarized antenna are flange interfaces.

Hardware Description 12 Cables
12 Cables
This describes the cables of the ODU. The cables of the ODU which consist of the IF cable
and ODU PGND cable.
12.1 IF Cable
The IF cable is used to connect the ODU with the IDU and transmits the IF signals O&M
signals and -48 V power between the ODU and the IDU.
12.2 PGND Cable of the ODU
The ODU PGND cable is used to connect the grounding screw of the ODU to the outdoor
ground point such as the ground point on the tower so that the ODU can be connected to the
outdoor grounding grid.
12.1 IF Cable
The IF cable is used to connect the ODU with the IDU and transmits the IF signals O&M
signals and -48 V power between the ODU and the IDU.
The IF cable can be categorized into three types: 5D cable, RG-8U cable, and 1/2-inch cable.
l If the distance between the IDU and the ODU is shorter than 120 m, the 5D cable is
used. The 5D cable has an N-type connector at one end connected to the IF interface of
the ODU and a TNC connector at the other end connected to the IF interface of the IDU.
l If the distance between the IDU and the ODU is from 120 m to 180 m, the RG-8U cable
is used. The RG-8U cable has an N-type connector at each end. One end is connected to
the IF interface of the ODU and the other end is connected with the IF jumper of the
IDU.
l If the distance between the IDU and the ODU is from 180 m to 300 m, the 1/2-inch cable
is used. The 1/2-inch cable has an N-type connector at each end. One end is connected to
the IF interface of the ODU and the other end is connected with the IF jumper of the
IDU.
When the ISM8 board works with the XMC-3H ODU, if the distance between the IDU and the ODU is
from 220 m to 300 m, the 1/2-inch common cable is used.

13.2 Information about Sub-band Combination of

XMC-3W ODU
This chapter introduces information about sub-band combination of XMC-3W ODU.
l The XMC-3W ODU is a wide-band ODU. The first columns in Table 13-3 and Table 13-4 list T/R
spacing and sub-bands supported by the same ODU. For example, 154A/161A/168A/196X indicates
that four T/R spacing and sub-bands are supported by one hop of ODU.
l The XMC-3W ODU T/R spacing and sub-band is newly defined. The mapping between T/R spacing
and sub-bands of XMC-3W ODU and XMC-3 ODU is listed in the second and third columns of
Table 13-3 and Table 13-4.
