IEC 61755-3 series, Fibre optic interconnecting devices and passive components Fibre optic connector optical interfaces 3 Description The parent connector for type LC connector family is a simplex plug connector set of plug/adaptor/plug configuration which is chara

32、cterized by: A 1,25 mm nominal diameter ferrule or, in the case of 1 mm OD POF, the fibre acts as the ferrule. The connector includes a single coupling latch and a ferrule spring loaded in the direction of the optical axis The plug has a single male key, which may be used to orient and limit the rel

33、ative position between the connector and the component to which it is mated. The optical alignment mechanism of the connectors is a rigid bore sleeve or a resilient sleeve. Drawings and dimensions provided consist of those minimum features that are functionally critical during the mating and unmatin
