IP QAM is new generation highly integration and high performance QAM modulator. It Is a item used modular design and each modulating module group can work separately. Each modulating module can be with IP TS input using UDP format through GE port, supporting at most 8 different IP address or port number, integrated 8 sets TS stream, input to 8 sets QAM(DVB-C) Modulator , and through 1RF port output 8 adjacent frequencies range as 48MHz-860MHz.1U case support at most 3 modules (24 QAM), this equipment is highly integrated, highly performance with low cost , quite suitable for the new generation CATV system. This item supports to configurate modulating parameters via local and remote control, which could instead of a few independent QAM modulator, to reduce the operator’s cost and save space.

* Fully support EN300 429/ITU-T J.83A

* GE port IP TS input, support 188/204 byte TS packet

* Each modules 8 adjacent QAM modulating carrier output via 1RF interface

* Support accurate PCR correction

* Support 16QAM,32QAM,64QAM,128QAM,256QAM modulate constellation

* Symbol rate range: 5.0 Mbauds ~ 7.0 Mbauds

* Support NIT insert, updating function

* RF output frequency 48MHz ~~ 860MHz

* Each module Rf output level - 20 dBm ~ ~0 dBm, 0.5 dB stepping

* Support network management (NMS)
