Abstract

The results of a 5000 hour life test at 85 degree(s)C/85% RH and of a 5000 hour life test at 45 degree(s)C/85% RH on commercial planar and fused-fiber optical branching devices are presented. The failure mode of planar optical branching devices is revealed by an increase of excess loss with a parallel increase of back reflection whereas the failure mode of fused-fiber optical branching devices is evidenced by splitting ratio variation. Failure analysis suggests possible degradation mechanisms for both types of devices. Furthermore Mean Time To Failure range has been estimated. Experimental results show that highly reliable couplers could be manufactured provided that a short period screening procedure is performed.
