1. Introduction
JZOT8320-KII series 1310nm optical transmitter is designed especially for the transmission of CATV signal,cable telephone and cable data.It has DFB doide as light source.First,It modulates through external modulator at the way of AM-VSB,then transmits the vedio and signal to optical receiver wihch then transfer to electrical signals,thereafter,the electrical signals will be distributed to all the subscribers.This equipment would be used for playing program or the long-distance transmission of the vedio&signal of HFC system.
