16 Channel Modulator System

SFM-1602-Z is combined fixed channel modulators based on space saving and high performance design principles. This system comprises of 16 modulators,1 Combiner, and a Hybrid IC Amplifier, which is housed together with highly efficient Power Supply in 4U standard rack. The 4U standard size rack can be installed in a 19″ Rack or can be fixed on the wall. IT can be used to assemble upto 80 channel Cable TV system. 5 Systems can be combined together to work as a High performance Headend.
