RFoG FTTx mini node
up to 1.1Ghz
Burst mode laser
Single fiber input/output
apply to CMTS system, DOCSIS
Features
· For FTTH
· Using the low noise pHEMT GaAs FET as the first RF amplify module, fit to low optic power input
· Support the universal HFC set-top box, cable modem and head-end equipment
· Transparent return path capability (protocol and modulation format agnostic)
· Optical AGC function ( reach the positive RF level)
· Reduce the convergence noise
· Local or remote power supply
· Die-casting aluminum housing, excellent heat dissipation performance
· It is compatible with DAVIC and DOCSIS
