35、 power variation induced by mechanical disturbance in optical receptacles and transceiver interfaces 1 Scope 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 distu
36、rbance 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 a

This part of IEC 62150 defines physical stress tests to ensure that such optical connections (cable and receptacle) can con

Methods A and B are applicable to the tests for the
44、 mechanical endurance of transceivers under wiggle Cases A and B, respectively. Table 1 Multiple test methods Test methods Applicable to Example of parameters to be included Method A Wiggle Case A: test for optical transceivers used with patchcord terminated to connectors which meet interface standa

46、ure, test jumper, test load 4.2 Two wiggle loss mechanisms 4.2.1 Rationale for two different wiggle loss test methods Some optical transceivers and receptacles are susceptible to fibre optic cable induced stress when forces are applied to the mated cable-connector assembly. Depending on the structur
47、e of fibre-optic connectors, two different points of action for the receptacle cause two different types of wiggle loss. The intention of Method A is to help ensure that the transceiver port design is robust enough to work with a variety of cables that meet interface standards available in the field
48、. The intention of Method B is to ensure port designs are robust enough to endure potential side loads during operation and installation with cables of known performance. To guarantee the mechanical robustness of optical transceivers under wiggle Case A and/or B, transceiver suppliers and users can adopt both Methods A and B if necessary, or can choose either Method A or B by the mutual agreement.
