Product Detail
NIS2000 RFOG noise switching Adopts time-division technology(TDM) as same as CMTS Reduce return accumulated noise Burst mode

 Summarize

   NIS2000 noise isolator adapts to advanced HFC network high-speed data services, effectively control over the return noise convergence,improve the network reliability. Adopt the wild-type metal shielding housing, can be added on the node, bi-directional amplifier’s ports, or the floor, directly fed from the uplink port to work. It adopts time-division control technology(TDM) as same as CMTS,use “burst” mode to “on” or “off” simultaneously with CM return signal, so that allowing only one NIS2000 port to communicate with CMTS head-end at any given time, greatly improved the intrusive noise. 

Features

·Support the common HFC set-top box, CM and head-end equipment

·Transparent return channel (protocol and modulation in any manner)

·Convenient power supply(directly feed AC60V from the uplink port,also can feed downlink)

·Reduce the noise convergence

·Compatible with DAVIC, DOCSIS standard
