An optical fiber connector with a housing configured to hold a plurality of optical fiber ferrules is selectively reconfigurable between a first configuration and a second configuration different from the first configuration. The housing can have different widths in the first and second configurations. The ferrules can have different ferrule arrangements in the first and second configurations. The optical fiber connector can be mateable with different types of receptacles in the first and second configurations. Reconfiguration can be achieved by disconnecting a rear housing from a plurality of front housings at first set of attachment points, rotating the rear housing 180° in relation to the front housings, and attaching the rear housing to the front housings at the second set of attachment points.

The present invention relates to the pluggable connection of an optoelectronic module with an optoelectronic connector assembly from a location exterior to the optoelectronic connector assembly. An optoelectronic module comprises a housing having a proximate end and a rear end in a longitudinal direction; a ferrule arranged adjacent to the proximate end of the housing; an electrical contact arranged adjacent to the proximate end of the housing and stacked with the ferrule in a vertical direction; a biasing members configured to bias the ferrule in the longitudinal direction once pressed; and a guiding member extending in the longitudinal direction and configured to guide the optoelectronic module connected to another optoelectronic module. The optoelectronic connection between the optoelectronic module and the optoelectronic connector assembly has blind mating features.

An optical coupling between an optical fiber and a grating coupler having a design angle, in the form of an optical bench having a structured reflective surface at which incident light is directed. The optical bench supports the optical fiber in optical alignment with respect to the structured reflective surface. The optical fiber is a single-mode fiber. The structured reflective surface turns light transmitted between the grating coupler and the optical fiber and includes a three-dimensional concave reflective surface profile that is structured to reshape the light transmitted between the grating coupler and the optical fiber to produce a mode field that matches the optical fiber input/output and the design angle of the grating coupler.

In a fiber optic backplane connection system, a backplane adapter assembly has a fiber optic adapter supported on a panel. The fiber optic adapter defines a plurality of connector ports arranged in a row. In a backplane connector assembly, a multi-connector chassis is mounted on a module body and is movable in relation to panel and the backplane adapter assembly along a z-axis. A plurality of push-pull fiber optic connectors are mounted on the multi-connector chassis and mateable with the connector ports. The multi-connector chassis holds the push-pull fiber optic connectors on the module body such that the push-pull fiber optic connectors are all simultaneously blind mated with the connector ports of the fiber optic adapter by the module body moving backward from the first position and the second position. Floating movement between the push-pull fiber optic connectors and the fiber optic adapter is permitted.

A lockable fiber optic connector assembly includes an MPO connector and a lock that is removably installable on the MPO connector at a locking position when the MPO connector is mated with the MPO adapter. The lock has forward and rearward facing locking surfaces. The forward facing locking surface opposes a rearward facing surface of the MPO outer release sleeve and the rearward facing locking surface simultaneously opposes a forward facing surface of the flange of the MPO inner housing when the lock is installed. The rearward facing surface will engage the forward facing locking surface and the forward facing surface will engage the rearward facing locking surface to block the outer release sleeve from releasing the MPO connector from the MPO adapter.

In a fiber optic connector, a ferrule body is received in a connector housing. A displaceable guide pin is movable in relation to the ferrule body. A spring yieldably biases the displaceable guide pin forward along a longitudinal axis of the fiber optic connector. The displaceable guide pin is displaced backward along the longitudinal axis in relation to the ferrule body and resiliently compresses the spring as the fiber optic connector is connected to another fiber optic component. In a multifiber ferrule assembly, a ferrule base is connected to a ferrule body. A displaceable guide pin is movably connected to the ferrule body for movement in relation to the ferrule body along a longitudinal axis between an extended position and a retracted position. A spring between the displaceable guide pin and the ferrule base yieldably biases the displaceable guide pin to the extended position.

Devices and methods for connecting optical fibers are provided. In some embodiments, connectors and adaptors for two-fiber mechanical transfer type ferrules are disclosed. In some embodiments, MT connectors, such as simplex, duplex, and quad micro-MT adaptors are disclosed. In some embodiments, MT adaptors, such as simplex, duplex, and quad adaptors are disclosed. In some embodiments, optical fiber cables that modularly coupled with at least one optical fiber connector, adaptor, and other optical fiber cable the cable is configured to provide a remote release from an adaptor receptacle.

A multifiber ferrule has a generally forward-facing angled ferrule contact surface that is skewed with respect to the widthwise axis of the ferrule such that the angled ferrule contact surface defines a widthwise skew angle with respect to the widthwise axis. A multifiber optical connector has a connector housing assembly that holds at least one of this type of ferrule. The connector housing assembly can hold two such ferrules so that the ferrule contact surfaces are angled in opposite widthwise directions and so that a broad side of the first ferrule opposes a broad side of the second ferrule in parallel, spaced apart relationship therewith. A polarity-changeable multifiber optical connector is also provided that includes a multifiber ferrule with a generally forward-facing ferrule contact surface at an oblique angle to the longitudinal axis.

A multi-fiber, fiber optic connector is interchangeable between a male connector and a female connector by including a pin retainer having a releasable retention device configured to lock the pins in place within the retainer. The retention device may be opened, for example, with a release tool, to free the retention pins for removal of the pins. A method for switching a connector between a male connector configuration and a female connector configuration may be possible as a result of the releasable retention configuration.

A fiber optic adapter assembly reduced in size from a SFP footprint to a SC footprint to accommodate a first fiber optic connector on a first side within one or more ports, and a second fiber optic connector on a second side within one or more ports. The first fiber optic connector is a duplex fiber optic connector with an overall length of about 50 mm and the second fiber optic connector is a behind-the-wall connector with an overall length of about 15 mm thereby reducing the overall length of a connector and adapter assembly for increasing optical fiber density.
