Thirty-two channels data transmission in fiber optic communication system based on CPLD

In order to reduce the transmission cost and make full use of the band source of fiber, the article introduces a new kind of fiber optic communication system which utilizes TDM and WDM alternatively to realize thirty-two-channel data transmission.Here we explain the method of the application of the encoder/decoder chip and CPLD in.The feasibility and applicability of the design are validated through experiments.The result indicates that this fiber optic communication system possesses great industrial potentials.
