    The document discusses optical cards and modules used in Apollo platforms, including: 1) An add card that combines 8 input signals and provides the combined signal at the output along with a monitoring port. 2) Mux/DeMux cards for 16, 44, or 88 DWDM channels that provide lower attenuation than other technologies. 3) The MXD44/MXD44_P card, a 44-channel C-band Mux/DeMux card with 100GHz spacing that occupies two slots. It has connectors for 44 input and output channels.

    The add section includes a 1 x 8 splitter that receives signals through eight input C1 IN to C8 IN connectors,
    combines them, and provides the resulting signal at the LINE OUT connector. An isolator on the output line
    prevents reflection from the connected WSS. In addition, a sample of the output add-signal is connected to
    the monitoring port MON, enabling monitoring the signal for test or maintenance purposes.

    8.3 Mux/DeMux Cards


    ECI Telecom offers a range of passive Mux/DeMux cards for Apollo platforms. The DWDM Mux/DeMux
    cards are based on flat-top technology, enabling back-to-back connectivity with lower attenuation
    compared to other technologies. With this configuration, minimal (if any) regeneration is required for the
    back-to-back Mux/DeMux connectivity. Mux/DeMux cards are available for DWDM with 16, 44, or 88
    channels.

    8.3.1 MXD44/MXD44_P
    The MXD44/MXD44_P is a DWDM Mux/DeMux card for 44 channels in the C band (Ch. 17-Ch. 60) with 100
    GHz spacing and E/W configuration. The MXD44/MXD44_P occupies a double slot in the OPT9624 and
    OPT9608 platforms. All connections to the card are made from the front panel and all connectors are LC
    type.
    The MXD44 and MXD44_P cards are very similar. The only difference between them is that the system
    management can detect and read the MXD44 properties (like the Serial No. and HW Rev.), while the
    MXD44_P is a totally passive and doesn't support this option.

    NOTE: The MXD44/MXD44_P is supported in the Artemis 1P/2PE/2A/4A platforms and in the
    following Apollo platforms:
    OPT9624
    OPT9608
    OPT9603

    Figure 8-24: MXD44/MXD44_P front panel

    The card two sections of the front panel are:


    Mux: Operates as a 44-channel C band multiplexer. This section has a group of 44 CHxx connectors (xx
    designates the channel number), each marked with the number of the channel in accordance with the
    ITU T Recommendation G.694.1 grid. The marking M at the right side of the panel identifies the
    corresponding multiplexer port input. The Mux output connector is identified as LINE OUT. The LINE
    OUT level can be monitored at the MON -20 dB OUT connector.
    DeMux: Operates as a 44-channel C band demultiplexer. This section has a group of 44 CHxx
    connectors (xx designates the channel number), also marked with the G.694.1 channel number. The
    marking D at the right side of the panel identifies the corresponding demultiplexer port output. The
    DeMux input connector is identified as LINE IN. The LINE IN level can be monitored at the MON -20 dB
    IN connector.
