    SR1002 Optical ReceiverEuropean version

    SR1002 is our latest high-class CATV network optical receiver. This equipment adopts
    GaAs MMIC amplify module. Optimization circuit design, coupled with the company 10
    years professional design experience, makes the equipment achieve high performance
    index. The parameters will be displayed by single-chip to make engineering debug be
    more convenient. It is the best choice for CATV network.

    . Performance Characteristics
    Advanced AGC control technique, when the input optical power range is 9
    2dBm, the output lever, CTB and CSO basically unchanged ; the AGC control range is
    adjustable;
    Downlink working frequency extended to 1 GHz, RF amplifier part adopts the high
    performance and low power consumption GaAs chip, the highest output level up to
    106 dBuv;
    EQ and ATT both use the professional electric control circuit, makes the control more
    accurate, operation more convenient;
    Built-in national standard class II network management transponder, supports remote
    network management (optional);
    Compact structure, convenient installation, is the first choice of FTTB CATV network
    equipment;
    Built-in power supply with high reliability and Low power consumption;

    1 Mode: Mode selection button, a total of eight modes, presses the mode selection button
    to enter the corresponding status display, eight modes to cycle.
    The following is the detailed instructions

    Input optical power (unit dB)


    : Means that the optical power is low or none
    : Means that the displayed data is the input optical power

    RF equilibrium, can be adjusted by

    or

    buttons, the maximum range is 15dB

    EQ mode, means that the controlled and displayed data is the RF channel
    equilibrium
    RF attenuation, can be adjusted by

    or

    buttons, the maximum range is 15dB

    ATT mode, means that the controlled and displayed data is the RF channel
    attenuation
    The actual number of channels enters into the current network system. It can be
    adjusted by the

    or

    buttons, the maximum number of channels is 200

    This menu is used to display the actual number of channels enters into the current
    network system, in order to calculate the RF output level more accurately
    RF output level of the equipment (unit dBuV)
    : Means that the displayed data is the RF output level of the equipment under the
    current system
    Operating temperature (unit )
    Displays the actual internal working environmental temperature

    The actual value of +8V working voltage


    Means that the displayed data is the actual value of +8V
    AGC adjustment range (adjustment range -4-9dBm)
    Press the

    or

    buttons to adjust and press Mode to confirm the data

    Means that the AGC range of the equipment under the current system is +2
    If the
    -9dBm
    displayed data is -4, means that the AGC range is +2-4dBm
    If the displayed data is -5, means that the AGC range is +2-5dBm
    If the displayed data is -6, means that the AGC range is +2-6dBm
    If the displayed data is -7, means that the AGC range is +2-7dBm
    If the displayed data is -8, means that the AGC range is +2-8dBm

    Note: AGC range per reduce 1dBm, the output level is raised by 2 dBuV
