LC标准光接口协议。 The parent connector for type LC connector family is a single position plug connector set of plug/adaptor configuration which is characterized by a 1,25mm nominal diameter 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 relative 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. , which may be used to orient and limit the relative position between the connector and the component to which it is mated.
