SDH/SONET(同步数字序列/同步光纤网络)需要高稳定、高精度的同步来处理经过网元的数据。网络产生的任何相位变化或者说抖动都会恶化传输质量,提高误码率,或者造成数据丢失。所以,理解抖动和它对网络性能的影响就变得至关重要。下面将详细讨论对用于SDH/SONET网络中的OC-48(2.5
SDH / SONET (Synchronous Digital Hierarchy / Synchronous Optical Network) requires high-stability, high-precision synchronization to process data passing through the network element. Any phase changes or jitter generated by the network can deteriorate the quality of the transmission, increase the bit error rate, or cause data loss. So, understanding jitter and its impact on network performance becomes crucial. The following discussion of OC-48 for use in SDH / SONET networks (2.5
