随着数据传输速率越来越高,业务种类越来越多,光口抖动要求也越来越高.协议中规定的B1抖动如何能达到标准中规定,而且在这种抖动的情况下,怎么还能级联更多的光口满足生产测试的需求已经是现在通信设备商的一个首要面临的问题.对功能处理单元中的高速光口的带宽和数字锁相环中的鉴相器的研究,调整了数字锁相环鉴相器的鉴相频率,找到了满足光口抖动指标的参数,在抖动满足的条件下,微调了高速光口的带宽,使得功能处理单元光口级联能力达到生产的指标要求,最终解决了抖动和级联这两个既有联系又互相制约的问题.

With data transfer rate increasing, more and more types of business, optical interface jitter requirements are also increasing. B1 jitter specified in the agreement how to achieve the standard provisions, and in the case of this jitter, how to cascade more light ports to meet the needs of production testing already is a primary issue now communication equipment manufacturers facing. The function processing unit in high speed optical bandwidth and digital phase-locked loop learning phase of the research, the adjustment of the digital PLL phase detector phase frequency, find the parameters satisfy burring jitter metrics and under the conditions to meet the jitter, fine-tuning the high-speed burring of bandwidth, the processing units of the cascade ability to meet the requirement of production, finally solved the jitter and cascading the two have both connection and mutual restrict problem.
