光纤通信系统中2/8转换单元的设计

2/8 change unit design for the optical fibre communication system

提出了以2/8转换芯片为核心的2/8转换单元的一种设计方案,将CPLD/FPGA技术与光纤通信技术结合,其技术指标符合ITU-T建议G．703的要求,使产品外围电路简单,成本低,可靠性高。

A design program for 2/8 change unit by using 2/8 IC as core is propozed in this paper, which combines the technology of CPLD/FPGA with optical fibre communication. The technology parameters of it are according with the demands of ITU-T G. 703. The periphery circuit of it is simple, which reduces the cost and improves the reliabilities of the product.
