【Abstract】 In this paper, a new designing scheme of gigabit rate digital fiber optic transmission system is introduced including multiplexer, encoder, decoder, demultiplexer, scheme design of trans- mitterand received, access and recovery of digitized video and multirate service, and high speed PCB design. Low cost G-Link chip is used in the system according to characters of digital fiber optic transmission. The experimental results show that the scheme is feasible and favorable.更多还原
