General Description

Optical receiver/node is one of key devices of HFC network, which receives and converts optical signal of CATV into electric signal on the basis of least additional noise and anamorphose, and transmits it via coaxial cable networks.

Main Feature

High performance PIN photodiodes and amplifier module, low noise, low distortion, lower optical power receive;Optical power lamp indication;AGC;High performance RF module, ensure the good C/N, C/CSO, C/CTB index;Fixed EQ and adjustable ATT, adjust the output level according to requirements;Multistage lightning protection devices, ensure long-time stable and continuous working in an adverse environment; Aluminum alloy waterproof; Excellent heat dissipation; Anti EMI/Radiation
