NIS2000 RF noise isolator
Adopts time-division technology(TDM)
Reduce return accumulated noise
Burst mode
AC220V or AC60V
Summarize
NIS2000 noise isolator adapt 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 “open” 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 equipmentTransparent 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 convergenceCompatible with DAVIC, DOCSIS standardDiagram
