COL5400A CATV Headend Modulator DVB-C QAM RF Modulator
Outline
The COL5400A QAM modulator is a high performance modulator developed according to DVB-C standard.
It can receive various TS come from encoder, multiplexer, DVB gateway, scrambler and video server, and
then disposes the TS by RS encoding, interleaving and QAM modulating. This device also has RF output
and real-time monitoring function.
