Reliability of non-hermetic optical transceivers

Analyse suitability of non-hermetic packaged transceivers for space applications. 

There is increasing interest in intra-satellite optical communications, which can be higher bandwidth, lower power, and better EMC compared to the electronic counterpart. Optical transceivers are at the core of such links. for the terrestrial market where transceivers are often delivered in non-hermetic packages but for space applications, non-hermetic packaged devices present higher risk. However, if the reliability of non-hermetic packaged devices can be demonstrated it can lead to an order-of-magnitude cost reduction. This activity encompasses the following tasks:- Procure a range of COTS non-hermetic (or semi-hermetic) optical transceivers for testing- Develop extensive test plan including humidity resistance, thermal sequences- Analyse failure mode, reliability evaluation, and acceleration law fitting- Conclude risk-reduction test methods for best evaluation of non-hermetic transceivers
