Abstract: A grinder for grinding an end face of a fiber includes a housing, a fiber fixing module, a base, a transmission shaft, and a grinding pad. The housing includes an annular rack wheel with an internal engaging teeth. The fiber fixing module is positioned on a top of the housing. The base is positioned at a bottom of the housing and includes an eccentric connection portion. An end of the transmission shaft is connected to the connection portion. The transmission shaft is sleeved with an annular pinion having external engaging teeth engaging with the internal engaging teeth. The grinding pad is connected to another end of the transmission shaft and revolves around the rotation axis of the base and rotates around its own rotation axis together with the transmission shaft and matches an end face of a to-be-ground fiber penetrating the fiber fixing module.

Abstract: A connector for ribbon optical fiber comprises a plug (1) and a socket (2). The plug (1) movably connects with the socket (2) through buttons (106) which are set on the both sides of the front end of the plug, and an alignment core (12) which allows a ribbon optical fiber movably aligning in the inside movement is also set on the front end of the plug (1). In the connector for ribbon optical fiber of present invention, the plug (1) movably connects with the socket (2) through buttons (106), therefore repeated plugging and pulling can be achieved, and the optical fiber movably aligns inside the alignment core with the advantages of simple structure and good effect of alignment.

Abstract: An optical fiber plug for high density optical fiber connections is proposed for matching with an optical fiber adapter, and includes a body with an elastic buckling member (130) to buckle the adapter, and an ejecting assembly actuated at the same time when the buckling member (130) is actuated to release the body from the adapter. The ejecting assembly includes an ejecting spring (420) and an ejecting rod (410) arranged in the body. The ejecting rod (410) is ejected from the body when the ejecting assembly is actuated, and stopped on the adapter to eject the body out of the adapter. The optical fiber plug can be automatically ejected out of the adapter when the buckling member (130) of the plug is actuated, thus solving the problem of operational difficulties caused by reducing the geometric size of the plug, and realizing high density optical fiber connections with optical fiber jumpers.

Abstract: Disclosed are an optical fiber connector an assembly method therefor. The connector is used for matching with an optical fiber adapter, and comprises a connector casing, a ceramic ferrule (2), a spring (4) and a boot (8), wherein the connector casing has a lateral width of 2.5 mm to 4.5 mm, is formed by inserting and locking a front casing (1) and a rear casing (5) and forms a cavity; the tail of the connector casing is connected to the boot (8), the external front end of the connector casing contains a guiding block (101) and a combined elastic arm successively in the rearward direction, and a retaining convex block (104) is arranged on the combined elastic arm; the tail end of the ceramic ferrule (2) is fixed to a tailstock (3) of the ceramic ferrule and penetrates through a through hole at the front end of the connector casing; and the spring is compressed between the tailstock (3) of the ceramic ferrule and a stop block (501) formed by the inner walls of the connector casing.

Abstract: A field installable optical-fiber connector at least comprises an optical-fiber splice sleeve with a hole for optical-fiber ferrule and an optical-fiber splice member containing-chamber. A first half and a second half of the optical-fiber splice member are placed in the optical-fiber splice member containing-chamber. An optical-fiber ferrule pre-provided with the connecting optical-fiber is inserted in the hole for optical-fiber ferrule.
