Pre-connector and connector
A pre-connector is configured to detachably fix to an optical fiber group. The pre-connector includes a shell assembly and a limiting member. The shell assembly is configured to accommodate one end of the optical fiber group. The limiting member is clamped in the shell assembly and is configured to press against the optical fiber group to fix the optical fiber group to the shell assembly. The present disclosure further provides a connector including the pre-connector.
