The Telecommunications Industry Association has published a new standard, Reliability of Fiber Optic Interconnecting Devices and Passive Components -- Part 7: Life Stress Modeling, TIA-1048.
The document is adopted IEC 62005-7.
This part of IEC 62005 describes a common set of procedures for estimating the reliability of optical fiber connectors, splices, branching devices and other passive components. This part deals specifically with component reliability as estimated from life tests that are accelerated in some manner as in the example of IEC 62005-2.
Since different material systems designed to do the same job will often respond in very different ways to the same stresses, in terms of both the form of the acceleration function and the statistical distribution of failure times (or degradation observed over time), a normative standard specifying specific methods of acceleration or statistical modeling is inappropriate. Instead, this Part 7 provides a minimal normative standard for presenting data and analyses to support reliability estimates of passive components and an informative portion (bibliography) containing references to more extensive writings on physical and statistical modeling for accelerated testing.
TIA-1048 was created by TIA FO-4.3 Subcommittee on Passive Optical Devices and Components and released April 2005.
The TIA is based in Arlington, VA. For more information visit www.tiaonline.org.
