Abstract: This application provides a pre-connector and a communications device. The pre-connector includes a connector component and an outdoor component. The connector component includes a ferrule base and a ferrule that is slidable relative to the ferrule base. The ferrule base is configured to fasten the optical cable, and the ferrule is connected to an optical fiber that is of the optical cable and that is inserted into the ferrule base. In this way, the optical fiber can be connected to the communications device by using the ferrule. The outdoor component includes: a spindle that is sleeved on the ferrule base and that is fastened to the ferrule base; and a handle sleeve sleeved on the spindle. The outdoor component is used as a connecting piece to be detachably fastened and connected to the communications device, so as to provide a locking force used when the communications device is connected.

Abstract: An optical fiber sub-assembly includes: a handle, a rear retainer, an optical cable, a field mountable connector (FMC) assembly, a spindle, and a protection hood fixedly connected to the spindle. An end of the optical cable is connected to the FMC assembly, the optical cable protrudes from a first end of the FMC assembly. The FMC assembly includes a ferrule provided at a second end of the FMC assembly. The spindle is sleeved outside the first end of the FMC assembly, and the protection hood is sleeved outside the second end of the FMC assembly. An end of the spindle that is away from the protection hood is connected to the rear retainer and is used to fasten the optical cable. The handle is sleeved outside the protection hood and the spindle.

Abstract: Embodiments provide a splice closure and a method for installing an optical cable. The splice closure includes a closure body, a cable accommodating tray, a nut component, an abutting member, and an elastic member. The abutting member is located between an optical cable and the nut component, and the elastic member is located between the optical cable and an installation tube. When the nut component is screwed to an externally threaded section of the installation tube by using threads of an internally threaded section, the abutting member abuts the elastic member, so that the elastic member elastically deforms under an abutting effect of the abutting member, so as to cause an inner circumferential wall of the elastic member that elastically deforms to abut the optical cable, and an outer circumferential wall of the elastic member that elastically deforms to abut an inner circumferential wall of the installation tube.
