 Bi-directional transmission HFC Two outputs node ERB802  

 

Products Description

ERB802 Outdoor Bi-directional Optical Receiver is main optical node device designed for receiving fiber signal in HFC network.

The optical receiving module mainly adopts PHILPS BGO747BO & BGO847BO, ORTEL 2609B or homemade PDAS-995-1, etc. It has good performance, well reliability, and low non-linear distortion and so on. Operate and maintain is very conveniently because of reasonable inside design and arrangement, and carefully-selected in material.

Consider of the network upgrade and complete in the future, this type adopts bi-directional structure, the users could choose the reverse transmitter unit according to their requirement.
