FTTH1021-TB New Product Mini Optical Fiber Node FTTH1021

Features

RFoG model, for all optical fiber network;
Design for reverse path burst, reducing the cumulative amount of noise moving over the upstream path on the fiber back to the hub the company maximizes the path distance and the signal-to-noise ratio at the upstream receive end;
Inside switching power supply.Specifications:
