Summry
1550nm Internal Modulation Optical Transmitter has been widely used in the applications of the multi- channel transmission. When the laser's chirp effect is reacting to the link dispersion of the fiber, there will be distortion on the receivers. While working with the EDFA, there will be serious CSO deterioration. The distortion and deterioration will increase with the distance getting longer and channels getting more. This series of 1550nm internal modulation CATV optical transmitter has chirp and dispersion compensation inside, which makes the system index perform excellently. It can be used as a transition solution, such as a town where the fund is in shortage and the area coverage is less than 10Km.
