The purpose of this part of IEC 62150 is to specify the test requirements and procedures for qualifying optical devices for sensitivity to coupled power variations induced by mechanical disturbance at the optical ports of the device. It applies to active devices with optical receptacle interfaces. In this edition, transceivers using small-form-factor connector cables (1,25 mm ferrule) for single mode fibre are specified.
It has been found that some optical transceivers and receptacles are susceptible to fibre optic cable induced stress when side forces are applied to the mated cable-connector assembly, resulting in variations in the transmitted optical power. This part of IEC 62150 defines physical stress tests to ensure that such optical connections (cable and receptacle) can continue to function within specifications.
