The forward one-way optical receiver module provides an optical input port and a RF output port. It is mainly used for optical fiber transmission of downstream analog TV signals, digital television signals and CMTS data signals in HFC networks. The optical receiving part adopts a high-response PIN tube or optoelectronic integrated module with up to 1 GHz band. The AGC or MGC can be switched and low noise amplifying components are selected to offer high CNR and low distortion.
● Support hot swap.
● Two-way redundant backup, can be switched automatically or manually.
● 870M/1002M band is optional.
● The AGC and MGC gain control modes are optional.
● PIN tube and photoelectric integrated module are optional.
● Two-way optical receiving isolation＞60dB。
