Design of Time Division MUX and DEMUX for Large Optical Transceiver

摘要

The working principle of large optical transceiver is introduced in this article, and the time division MUX and the time division DEMUX are designed by the online system programmable technology and the FPGA (Field Programmable Logic Array), including hardware design, software design, and testing. The transmitting design and the receiving design method of time division MUX are introduced in detail, and a kind of time division MUX method based on synchronic control character is designed to realize the reliable transmission of VGA signals, PAL signals, voice signals, digital IO, USB data, and network signals, which is helpful and practical to enhance the capacity of transmission channel and save the fiber resources.
