该论文提出了一款基于最大似然序列估计（MLSE）的10Gb/s电子色散补偿集成电路，用于解决波分复用（WDM）光网络中的快速功率瞬态问题。通过电子域补偿替代传统光学方案，实现了对光信道功率突变的快速响应与信号恢复。
Finisar Corporation, Champaign, IL University of Illinois at Urbana-Champaign, Urbana, IL 2 Optical add/drop multiplexers (OADM) are being used in WDM networks to improve bandwidth efficiency by reconfiguring channel capacity on-demand. However, abrupt addition/dropping of channels creates cross-gain saturation in erbium-doped fiber amplifiers triggering fast power transients in the surviving channels (see Fig. 11.8.1). Typical power transients of +9dB/100µs and -3.5dB/100µs are observed in currently deployed OADM-based WDM networks. Existing solutions to this problem are in the optical domain such as dynamic gain equalizer (DGE) and variable optical attenuator (VOA). In this paper, a receiver IC is designed to recover data and clock in OC-192 (9.952Gb/s-12.5Gb/s) OADM-based SONET WDM metro and long-haul networks. This is an electrical solution integrated into the receiver IC to address the power-transient problem for OC-192 links. An electrical solution reduces the
