Product Details

Modularization Design CATV Optical Receiver Optical Workstation GWS1000H4J/F-G+(CMC)

GWS1000H4J/F-G+(CMC) is an ideal solution for two-way HFC networks. The most noticeable feature is modularization design, and provides good redundancy. It could be loaded maximum 2pcs forward-path optical receiver modules, 2pcs return-path optical transmitter module, 1pc NMS module and 1pc Switch Power supply, with CMC signal insert function, 4 independent RF outputs.

● Modularization design and good redundancy.
● 1290~1580nm optical wavelength, -7~+2dBm optical AGC.
● RF working frequency up to 1GHz.
● 4 Independent RF outputs, level ≥108dBμV, fixed equalizer and attenuator for each port
● Support 4 independent test point
● Built with Tri-State-Switch on return-path to remotely set bridge, -6dB attenuator, switch off by NMS
● Support CMC return-path, forwarder-path and return-forwarder mixed RF interface, perfect support Docsis EOC solution.
● Digitalize display
● Metal die-casting waterproof housing, suitable for outdoor installation.
