Abstract
There is provided a method and device for forwarding a digital signal arranged into portions that each contain a timestamp and an error detection code. Duplicates of the digital signal are received on a first optical path and a second, separate optical path. Corresponding timestamps are identified in the signals and used to synchronize corresponding portions of the signals. The error detection codes in the synchronized portions are used to allow one and only one of the corresponding portions to be selected for forwarding. The selected portions are then forwarded.
