Outline
COL5400B 8in1 IP QAM module is the latest generational QAM modulator with high integrated level and performance. The
modular design of this device makes each of its daughter cards stand-alone when operating. Besides, each daughter
card can receive the UDP format TS through GE port, furthermore, it supports up to 10 different IP address or port No.
This device is combined 8 multiplexers with 10 channels inputs and 8 QAM (DVB-C) modulators, which can output
adjacent channel RF carrier(48M~860M)through the two RF output interfaces (4 carriers for each). Additionally, the
1U chassis for this modulator supports up to 3 modules (24 channels QAM) while the 4U chassis supports up to 12 modules
(96 channels QAM). This 8in1 IP QAM modulator has excellent integrated level, powerful performance and low cost, which is
special adequate for the new generation CATV system.
