Abstract
A padding unit comprising one or more fiber paddings is provided. Each of the one or more fiber paddings is for a respective one of one or more pairs of coupled channels in an optical device. At each pair of coupled channels, one channel in the pair of coupled channels is used as an upstream channel and the other channel in the pair of coupled channels is used as a downstream channel. Each fiber padding comprises a padding length of fiber configured to offset at least a part of a latency imbalance at the respective pair of coupled channels, the latency imbalance being a difference in latencies between the respective upstream and downstream channels caused by a difference in the multiplexing or demultiplexing path lengths of the respective upstream and downstream channels.
