IP EDGE QAM

Cable IP EdgeQAM Modulator


Product Overview

Cable TV IP EDGE QAM Modulator is designed to support a variety of applications including Video-on-Demand (VOD), Digital Video Gateway (IP to QAM),Modular Cable Modem Termination System (M-CMTS). It makes full use of the bandwidth of Gigabit Ethernet;a single machine can support 8 to 48 QAM channels,and can flexiblely place at the headend, branch headend or the convergentpoint of fiber optic.

IPQ6800 provides a solution with high density,high flexibility,high quality and lower price for the broadcast and television operators to develop VOD service.It multiplexes the program streams which input from multiple GbE-IP backbones network to specified multi- service transport stream, and then go through with QAM modulation and frequency conversion, and finally output RF.


IPQ6800 The chassis has six QAM RF module slots; each module has two QAM RF ports. Each port is capable of supporting up to 4 adjacent and/ or non-adjacent QAM channels on ITU-T,J.83A, The system can host two AC power supplies,which are redundant to each other.
