| Abstract: | Laser is the key component in multichannel optical fiber CATV system for improvement of the signal quality,especially in 1 550 nm VSB-AM system based on the G.652 optical fiber because of the dispersion and nonlinearity. In this paper,considering the intrinsic characteristic of the laser and the transmission characteristic of the fiber, performance demands on the laser in the system are discussed and typical performance parameter of the laser is presented. Several kinds of new lasers could be used in the system and their development is introduced as well. |
