TIA Publishes Fiber Testing Procedure Standard

The Telecommunications Industry Association (TIA) published a new test procedure (TIA-455-198) for measuring polarization dependence of insertion loss of single-mode fiberoptic components. The test procedure can be applied to any single-mode passive component, including connectors, splices, couplers, attenuators, isolators, switches, multiplexers and demultiplexers, optical amplifiers (non-operating), circulators and filters.
