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.

Redundant channel implementation to extend optical transceiver lifetime and reliability

Methods of aligning lens carriers and ferrules with alignment frames during assembly of optical cable connectors are disclosed. In one aspect, a method may include coupling an alignment frame with a circuit substrate, aligning a lens carrier with the alignment frame, and aligning a ferrule with the alignment frame. Other methods, apparatus, and systems incorporating the apparatus are also disclosed.
