Abstract: A pre-assembled optical fiber connector is provided that comprises a boot, a sleeve, a spacing sleeve, a tubular housing, a spring, an alignment ferrule, a push-pull insulative housing and a push-pull element which are assembled in series. The alignment ferrule has at least one engaging portion to engage the tubular housing so that the tubular housing, the spring and the alignment ferrule are pre-assembled.

Abstract: An optical fiber connector comprises a main body, two ferrules, an adapter, a keying element and a shroud. The main body has a first side wall, a second side wall, a third side wall opposite the first side wall, a fourth side wall opposite the second side wall, two latching arms respectively extending out from the first and third side walls, and two receiving bases attached to the second side wall. Each of the latching arms has at least one latching lug. The two ferrules are received in the receiving bases. The adapter is connected to the fourth side wall of the main body, wherein an optical fiber cable extends out from the adapter and is divided into two parts in an interior of the main body, and the two parts of the optical fiber cable are connected to the ferrules. The shroud movably envelops the receiving bases and has two through holes corresponding to the ferrules and at least one latching hole corresponding to the latching lug.

Abstract: The present invention provides an optical fiber connector adapted for connecting an optical fiber carried in the optical fiber connector to an optical cable, which comprises a plug, a ferrule assembly mounted in the plug, a retention member engaged with the plug, and having a first end and a second end, a resilient element mounted between the ferrule assembly and the retention member, a crimp member having a third end and a fourth end engaging with the second end, an extension member connecting thereto the optical cable, attached to the crimp member at the crimp member at the third end and having an entrance end, and an adjuster mounted between the second end and the fourth end for adjusting an engaging extent therebetween.
