External Optical Transmitter

1550nm


1550 external optical transmitter is desinged especially for the transmission of CATV signal, cable telephone and cable data. It has DFB diode as light source.First, it modulates through external modulator at the way of AM-VSB, then transmits the video and signal to optical receiver which then transfer to electrical signals, thereafter, the electrical signals will be distributed to all the subscibers. This equipment would be used for playing program or the long-distance transmission of the video & signal of HFC system
