Client-side fast optical receiver recovery using optical interconnects with DSP

The present disclosure relates to a system and method for fast digital signal processor (DSP) optical receiver recovery, i.e., for configuring an optical modem on the client side. This approach can be used in optical protection switch applications to allow fast switching between two client links, i.e. Within 50 ms. A receiver (Rx) digital signal processor (DSP) (20) in an optical receiver includes a processor configured to detect (102) traffic disruption on a current link, enter (104) a delay period, and perform one of the following (106): i) receive good traffic within the delay period; ii) expiring the delay period, thereby issuing a notification to the host device and retraining to acquire the optical signal. 本公开涉及一种用于快速数字信号处理器(DSP)光接收器恢复的系统和方法，即用于配置在客户端侧的光调制解调器。这种方法可以用于光保护开关应用，以允许在两个客户端链路之间快速切换，即在50ms内。光接收器中的接收器(Rx)数字信号处理器(DSP)(20)包括配置为检测(102)当前链路上的流量中断、进入(104)延迟期以及执行以下之一(106)：i)在延迟期内接收良好流量；ii)使延迟期到期，从而向主机设备发出通知并重新训练以获取光信号。
