Abstract
Embodiments introduce redundant optical channels to significantly extend the lifetime of parallel optical transceivers. A plurality of transmitters, N, transmit on a plurality of optical channels, where N is an integer number of optical channels greater than 1. One or more redundant channels, M, are also provided. N+M multiple input shift registers provide multiple paths for signals from each of the transmitters to connect to N+M laser diodes. In the event up to M of the N+M laser diodes fail, the multiple input shift registers connect the N transmitters to functioning ones of the N+M laser diodes thus extending the life of the device. A corresponding scheme is also described for the receiver side.
