Optical fiber test connector for LC and MU type test and emergency use

The invention discloses an optical fiber test connector for LC and MU type test and emergency use. The optical fiber test connector comprises a tail sleeve, a lock plate, a tightening cap, a spring, and a ceramic core component. The ceramic core component includes a tailstock and a ceramic core installed in the tailstock. The specification and dimension of the ceramic core is the same as the ceramic cores of an LC optical fiber connector and an MU optical fiber connector. The tailstock is provided with a slot matching the lock plate. The lock plate is arranged on the slot. The spring sleeves the tailstock, and the end of the spring contacts the lock plate. The end of the tailstock is connected to the tail sleeve. The tightening cap sleeves the outside of the joint of the tail sleeve and the tailstock. The optical fiber test connector for LC and MU type test and emergency use can be inserted into an LC type adapter, an MU type adapter or an active device socket.
