Abstract: The present application provides a clamping instrument, mainly including a locking structure being capable of performing switching action between a locking state and a non-locking state, and a plurality of clamping structures which are connected to the locking structure and capable of being linked with the switching action of the locking structure, so as to adjust each of clamping angles formed by each of the clamping structures, wherein each of the clamping angles formed by each of the clamping structures is adjusted to allow each of the clamping structures to clamp or release each of target tissues; and wherein when the locking structure is in the locking state, the locking structure will apply a continuous pushing force to each of the clamping structures, such that each of the clamping angles formed by each of the clamping structures is maintained to be minimum, thereby clamping each of the target tissues.

Abstract: A fiber optical connector assembly with a crimp tube assembly improves tensile load on the optical fiber cable or microduct jacket when the connector assembly is used as part of an optical network that is secured between towers spaced apart 1,000 meters or more. The crimp tube assembly has one or more crimp zones, and the crimp tube assembly has a lip formed on an inner surface of the crimp right assembly to improve tensile strength when the crimp tube assembly is secured to a back post of a first fiber optic connector assembly that is air blown or push through a duct or conduit. An epoxy resin may be injected into a cavity between the cable jacket and the crimp tube assembly to improve tensile load strength.

Abstract: A fiber optic connector having a ferrule that forms an optical connection with another fiber optic connector. An outer housing supports the ferrule and has a front end portion and a longitudinal centerline axis. The front end portion includes a front end face with a portion of the ferrule being forward of the front end face. The front end portion includes a protector that is shaped and arranged to protect the ferrule. The protector is arranged so that the fiber optic connector and another fiber optic connector of identical construction can, starting in the same orientation, be mated together by rotating said other fiber optic connector 180° about an axis perpendicular to the longitudinal centerline axis, aligning the longitudinal centerline axes and moving the fiber optic connectors along the longitudinal centerline axes until the fiber optic connectors are mated to form the optical connection.

Abstract: A fiber optic ferrule sub-assembly for insertion into an outer housing of a fiber optic connector includes a ferrule assembly having a ferrule that forms an optical communication connection with another fiber optic device. A back housing includes a back post to be attached to a fiber optic cable. A spring is operatively disposed between the ferrule assembly and the back housing. A linkage connects the ferrule assembly to the back housing such that the spring is compressed and biases the ferrule away from the back housing prior to insertion of the fiber optic ferrule sub-assembly into the outer housing.

Abstract: The present disclosure discloses a modular hardened optical fiber connector and an assembly method thereof. The modular hardened optical fiber connector comprises: a ferrule stub module which comprises a pre-installed optical fiber; an optical cable holding module which comprises an optical drop fiber of an optical drop cable; an optical fiber protection module which is arranged around a connection portion between the pre-installed optical fiber and the optical drop fiber; an inner housing module which accommodates the ferrule stub module, the optical cable holding module and the optical fiber protection module therein; and an outer housing module which accommodates the inner housing module therein.

Abstract: Splicing or connecting optical fibers extending from a first ferrule and a second ferrule is accomplished using heat or epoxy. Two half ferrules of differing dimensions or the same dimensions are secured together using a pair of guide pins. One of the two ferrules is biased by a spring forward and against a second ferrule to form the mechanical transfer ferrule. The mechanical transfer ferrule is secured within an inner housing of a fiber optic connector by a spring push that is secure to a distal end of the inner housing. A slidable outer housing biased forward by an elastic arm that ensures the fiber optic connector with the spliced two half ferrules is secured within an adapter port.

Abstract: The present invention discloses a type of optical fibre connector, comprising: an external shell; an internal shell, installed within said external shell; an inserted core component, contained within said internal shell and comprising an inserted core and a length of optical fibre pre-installed within said inserted core; and a spring, contained within said internal shell and located behind said inserted core, and being for exerting a pre-set axial force on said inserted core. Said internal shell includes a front part and a rear part; said rear part is assembled on said front part. Additionally, said spring is compressed between said rear part and said inserted core. In the present invention, the rear part can act as a retainer for the compressed spring and can also be for securing the Kevlar fibre extension tube of the optical cable.
