Design of integrated services signal optical fiber transmission based on FPGA

摘  要:为了节约成本,提高数据传输业务量,并保证数据业务高可靠性传输,提出1+1光纤保护点对点传输设计。采用数字光纤热备份技术和大规模可编程逻辑器件(FPGA)相结合,选择在两根光纤中同时双向传输8路音频信号、8路RS422信号和8路TTL电平信号,其中一根光纤作为主通道进行通信,另一根光纤作为热备份通道进行通信,在保证当一光纤损坏的情况下,另一根光纤还能正常传输,这样保证传输链路的可靠。

In order to cut down the cost, improve data transmission traffic and to ensure the reliability, the de- sign of 1+1 protection in optical fiber peer-to-peer transmission was proposed. This paper adopts the combina- tion of digital optical fiber hot standby technology and Large-Scale Field--ProgrammableGateArray(FPGA), realizes the simultaneous and bidirectional transmission of 8 audio signals, 8 RS422 signals and 8 TTL signals in two optical fibers, one of them used as main channel to transmit signal, the other one used as hot standby channel, this ensures the normal transfers in the event of damage in any one fiber and take guarantee the relia- bility of transmission link.
