摘 要: 提出了一种光传输设备中背板业务总线的2:5保护方法。在5路TFI-5总线的传输中,只需为其增加两条冗余路径,当接收端接收到的7路信号中有任意2路信号出错时,都可以从剩余的5路信号中解码出原来所要传输的5路TFI-5总线业务信号。设计了编解码逻辑电路,经测试表明该方法可以有效地保护背板业务总线。 A kind of 2:5 protection method of backplane TelecomBus in optical transmission equipment is presented. By adding two redundant paths to 5-way TFI-5 bus, the receiving end can decode from the remaining 5-way signal when any 2-way signal was broken. The encode and decode logic circuits were designed, the test shows that 2:5 protection method can protect backplane TelecomBus bus effectively.
