Abstract: An optical connector holding one or more optical ferrule assembly is provided. The optical connector includes an outer body, an inner front body accommodating the one or more optical ferrule assembly, ferrule springs for urging the optical ferrules towards a mating receptacle, and a back body for supporting the ferrule springs. The outer body and the inner front body are configured such that four optical ferrule assembly are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight optical ferrule assembly are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A receptacle can hold one or more connector inner bodies forming a single boot for all the optical fibers of the inner bodies.

Abstract: A multi-fiber push on (MPO) optical connector includes a housing supporting a ferrule body. The ferrule body forms an optical connection with a second MPO optical connector. The ferrule body includes a connection end having a distal end face arranged to face the second MPO optical connector when the ferrule body forms the optical connection with the second MPO optical connector. The connection end of the ferrule body defines a recess extending proximally into the ferrule body from the distal end face. A plurality of optical fibers are received in the ferrule body. Distal ends of the optical fibers are adjacent to a proximal end of the recess such that the distal ends of the optical fibers are spaced apart from the second MPO optical connector when the ferrule body forms an optical connection with the second MPO optical connector. The distal ends of the optical fibers are coated with an anti-reflective material.

Abstract: In a connector for terminating a cable, a connector housing has a rear end portion including a first shoulder. An inner connector assembly is received in the connector housing. The inner connector assembly includes at least one ferrule exposed and a back body with a back post. At least one strength member is secured to the back post. A rear bracing member is received in the connector housing. The rear bracing member has a front end portion and a rear end portion spaced apart along the longitudinal axis. The front end portion of the rear bracing member is configured to engage the back body and the rear end portion of the rear bracing member is configured to engage the first shoulder of the connector housing such that the rear bracing member substantially braces the back body against rearward displacement along the longitudinal axis relative to the connector housing.

Abstract: A connection system for a printed circuit board employs either an inline or transverse board-mounted connector for holding board-mounted optical fibers. A plug-in connector can blind mate with the board-mounted connector. The plug-in connector has a plug-in connector body, a plug-in ferrule, and a plug-in ferrule holder. The plug-in holder latches with the plug-in connector body at either of two positions to selectively configure the plug-in connector for blind mating with either the inline or transverse board-mounted connector. The board-mounted fibers can be supported by a board-mounted ferrule assembly including a ferrule and a ferrule holder that is configured to selectively attach the board-mounted ferrule assembly to either of an inline board-mounted connector body and a transverse board-mounted connector body.

Abstract: A behind-the-wall optical connector an outer housing configured to be inserted into an adapter with a corresponding inner surface, a ferrule included in an annular collar to mate with a corresponding projection at an adapter opening, and a latch attached to one side of housing configured to lock the connecter into an adapter opening. The latch is further configured with a locking channel and guide to accept a pull tab with a catch at one end, the pull tab releases the connector from the adapter opening when the tab is pulled rearward or away from the adapter.

Abstract: An outdoor rated ingress protected connector assembly is formed by a mating connector and a first connector. A lock ring secures the mating connector and first connector together. An outer collar nut is displaceable to unlock the connector assembly to gain access to the internal components. The mating connector and first connector have a fiber optic connector secured therein, which form a transmission pathway when the connector assembly is formed.

Abstract: An optoelectronic module and optoelectronic connector assemblies can be used for releasable connection of a laser source to the module from a location exterior to the module. The construction of the optoelectronic connector assemblies is such that both in connection and disconnection, the electrical contacts are broken before the optical contacts so that the laser may power down before the optical connection is broken. The optoelectronic connection assemblies have blind mating features. Some versions are free of any latching or mechanical interconnection of the optoelectronic connector assemblies to each other. A spring has a construction which permits it to be received onto a cable by lateral movement of the spring.

Abstract: A parallel optical fiber angled coupling component, which is used for parallel coupling of optical signal between the optical fiber array and the laser array, comprises an optical fiber positioning substrate, a cover plate and a plurality of optical fibers. The end face of the optical fiber is polished into a bevel with an inclination of 42.5° or 47.5°, and the bevel of the optical fiber is coated with a metal reflective film. This invention has the following beneficial effects: The end face of the optical fiber is polished into a bevel with an inclination of 42.5° or 47.5° to reduce inter-modal dispersion and increase the transmission distance of the optical signal in the subsequent optical fiber; the bevel of the optical fiber is coated with a metal reflective film, so as to ensure high reflectivity even if the bevel of the optical fiber is covered with glue.
