30 April 2003 Passive optical components: from degradation data to reliability assessment
Author Affiliations +
The past decade has seen a huge increase of demand for fast data communication; this stimulated the optical research towards the design and development of both terrestrial and submerged long-haul full-optical transmission systems. More specifically, the submarine systems are required to be highly reliable: minimum lifetime of 25 years with very low maintenance, which implies the request for long term reliability for each component. In this work a reliability estimation approach based on hi-rel optical component degradation study is discussed. Results of a long-term test performed on optical isolators for submarine applications are reported. The experimental optical bench set-up, based on switching matrixes, developed at Pirelli Reliability Labs is also presented.
