Abstract: A high density optical fiber switch module comprises a box body whose front end is provided with several optical fiber adapters, the top surface or bottom surface of the optical fiber adapter is provided with a first positioning groove which extending along the direction perpendicular to a direction in which the optical fiber plug is inserted into the optical fiber adapter, and a first positioning protrusion matching with the first positioning groove is arranged on the inner surface of the box body so that when the first positioning protrusion is latched within the first positioning groove, the optical fiber adapter is fixed to the front end of the box body.

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 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 and 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.
