Forward Path Optical Receiver YTOR286GM / YTOR286GS

Key words:

Other Headend Devices

Classification:

Other Headend Devices

Product Description

The forward path optical transceiver 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 devices 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.
