Optical HFC Receiver with Reverse Transmitter (HR2071)

Product Overview

Description

Optical HFC receiver with reverse transmitter

7 way return path HFC receiver, 1 way reverse optical transmitter

 

Product description

 

HR2071 series of  seven-way return path HFC receiver, one way reverse optical transmitter, mainly used at the head-end to convert upstream optical signal to RF signal at the user side. Moreover, send back the data at sub-HE to main head-end through one way of DFB return path transmitter. Eight independent units integrated into a 1RU 19" casing to provide service for HFC network terminal of ONTs. The receivers’ low noise design of -22dBm receive sensitivity, allow to supply service to farther distance.

 

Produt feature

1. 7 low noise optical receiver, up to -22dBm receive sensitivity.


2. One way return path transmitter can send back the data at sub-HE to main head-end.


3. 1200~1620nm wide wavelength


4.  SNMP network management function option


5.  RF output level can be adjusted by network


6.  Built-in 1+1 backup power, redundant A/B inputs (option)

 

Main application

• HFC network sub-HE

Up-stream optic HFC receiver
