Subject: Failure rate of Fibre Optic Cables
Can anybody provide me with a generic failure rate of fibre optic cables (single core and multi core)or a good source of information that will allow me to calculate a failure rate.
Thanks in advance.

After searching a number of data sources, I found a report that was produced back in 1988 that contained real data. This report is RADC-TR-88-124, "Impact 0f Fiber Optics on System Reliability and Maintainability" by N.C. Christian and L.K. Passauer. The data for multicore cables indicated that the inherent failure rate is 0.0019 failures per million hours per "sheath-kilometer". This is based on 28 million sheath-kilometer hours and one failure. Cable splice data indicates that the failure rate is 0.0004 failures per million hours per splice. This is based on 8 billion splice hours and no failures.
