Abstract: A multi-fiber, fiber optic connector may include a reversible keying arrangement for determining the orientation for plugging the connector into an adapter to thereby allow for a change in polarity of the connection to be made on site. The connector housing may be configured to engage with a removable key that may be engaged with the housing in at least two different locations to provide the plug-in orientation, or the housing may have slidably displaceable keys movable between multiple positions on the housing.

Abstract: An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer body, an inner front body accommodating the two or more LC-type optical ferrules, 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 LC-type optical ferrules are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight LC-type optical ferrules are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A mating receptacle (transceiver or adapter) includes internal alignment slots configured to accept a corresponding alignment key on connector outer housing to ensure alignment and orientation for maximum signal transfer between opposing ferrule end faces.

Abstract: Cross-compatible VSFF connection systems include optical connectors that are compatible with at least two types of adapters and adapters that are compatible with at least two types of optical connectors. Optical connectors have one or both of connector latch recesses and depressible latches, and likewise adapters have one or both of adapter latch arms and adapter latch recesses. Dual latch function connectors and adapters are capable of connection to a mating components that have only one type of latch structure, e.g., only recesses or only latches. Connection systems can be duplex or MT and may facilitate push-pull boot remote release and polarity change.

Abstract: A connection system may include fiber optic connectors and an optical receptacle into which the connectors are plugged. The fiber optic connectors are constructed so that the width of the connectors is small. Eight fiber optic connectors can be received in an opening of a QSFP style transceiver.

Abstract: A ferrule holder assembly can support groupings of a transceiver ferrules in an optical connector interface of an optical transceiver. A first holder body holds a first grouping of transceiver ferrules and has a holder-to-holder interface. A second, typically identical, holder body holds a second grouping of transceiver ferrules. The holder-to-holder interface of the first holder body engages the holder-to-holder interface of the second holder body to operatively align the first holder body with the second holder body to position the first grouping of transceiver ferrules and the second grouping of transceiver ferrules in the optical connector interface for making optical connections to one or more optical connectors plugged into the optical connector interface. The ferrule holder assembly can be used in combination with pre-terminated fiber arrays to couple an optical interface to a circuit board in a transceiver.

Abstract: 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.

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: Fiber optic network systems are implemented, at least in part, using very small form factor (VSFF) interconnect components such as VSFF duplex connector; VSFF mechanical transfer ferrule (MT) connector; VSFF duplex uniboot connector; VSFF MT uniboot connector; VSFF duplex adapter; VSFF MT adapter; VSFF duplex pluggable transceiver; VSFF MT pluggable transceiver; VSFF patch cable assembly; VSFF trunk cable; and/or VSFF breakout cable. The VSFF fiber optic network systems can define fiber breakout cabling that connects large trunk cables to many peripheral network locations. The network systems can define branches and sub-branches from a trunk cable. The network systems can define cross-connect sub-networks between sets of transceivers or adapters. The network systems can define a trunk-to-transceiver cabling assembly for connecting a trunk cable to at least 32 transceiver ports.
