30、ily of connectors. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (
31、including any amendments) applies. 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
34、g sequences of the plug with its adapter/receptacle counterpart component. The provided dimensions might cause intermateability problems with plugs not compliant to the standard. 4 Interfaces This standard contains the following standard interfaces: Interface 20-1: simplex plug connector interface P

38、F 1 mm The plug of interface IEC 61754-20-1 and interface IEC 61754-20-4 has a ferrule with a spherically polished endface (PC) shown in Figure 2a. The plug of interface IEC 61754-20-7 and interface IEC 61754-20-8 has a ferrule with a spherically polished angled endface (APC) shown in Figure 2c. The
39、 plug interfaces IEC 61754-20-9 through IEC 61754-20-12 have a flat smooth endface shown in Figure 2b (POF only). Plug interfaces IEC 61754-20-9 and IEC 61754-20-10 (POF 1,25 mm jacketed OD) have a POF fibre of up to 0.750 mm in a 1,25 mm OD ferrule. Plug interfaces IEC 61754-20-11 and IEC 61754-20-
