Optical Platform

Product Description
Features
Parameters

The forward path optical transceiver module is mainly used in the headend and sub-headend equipment rooms of the HFC networks, receiving the downlink optical signal and converting it into RF electrical signal, and amplifying it to the signal level required by the customer, and then used as the signal source of the optical transmitter and RF amplifier modules after the distribution network.

Used high-performance photodetectors, which can ensure excellent CNR indicators at lower optical input.
The output stage amplifier uses high-performance GaS module to ensure that the output CSO/CTB index is excellent.
Built-in AGC/MGC function, the optical input AGC range is -7~+2dbm,it also can be user-defined.
Built-in equalization, which range is 0~10dB.
One-way or two-way distribution output type optional.
Two-channel optical inputs type optional, with built-in RF switching function, which can realize automatic/manual switching of the optical path according to the input optical power or RF level of the optical paths.

●RF amplifier module is mainly used for cable television headend room, for HFC network downlink signal transmission

device, the input signal amplification to the customer the desired signal level, the distribution network as a light emitting

module drive signal source.

●the built-in two-stage amplification and pre selection of Low Noise GaAs push-pull module, output stage selection of

high performance GaAs power doubler module, to ensure RF amplifier module output parameters is excellent.

●the built-in AGC/MGC function, can be switched to set, AGC reference level can be set; built-in power balance, all support

optical platform menu settings.

●the input / output terminals are designed with high pass filter, in order to isolate the link noise; and a module

overvoltage protection circuit, to prevent the impact of static electricity and low frequency impact, in order to ensure

the reliability of the module.

●through the platform optical liquid crystal display to monitor RF input / output level, AGC/MGC state control, equilibrium

volume settings, AGC reference level values and parameters of various voltage, and can be realized through optical

platform RF amplifier module of remote network monitoring.
