A connectorized fiber optic cabling assembly includes a loose tube fiber optic cable and a connector assembly. The cable has a termination end and includes an optical fiber bundle including a plurality of optical fibers, at least one strength member, and a jacket surrounding the optical fiber bundle and the strength member. The connector assembly includes a rigid portion and defines a fiber passage. The connector assembly is mounted on the termination end of the cable such that the optical fiber bundle extends through at least a portion of the fiber passage. The plurality of optical fibers undergo a transition from a ribbonized configuration to a loose, non-ribbonized configuration in the rigid portion of the connector assembly.

A fiber optic connector port arrangement includes at least one upper receptacle and at least one lower receptacle vertically aligned with the upper receptacle to form a column of receptacles, the column including a center divider that divides the at least one upper receptacle from the at least one lower receptacle, the center divider defining latching shoulders for mating with latches of both a connector to be mounted at the upper receptacle of the column and a connector to be mounted at the lower receptacle of the column.

An optical fiber connector sub-assembly for an optical fiber connector including a ferrule configured to hold an optical fiber therein along an axis of the connector, a ferrule holder configured to hold the ferrule at a front portion of the connector, a ferrule housing including a front portion configured to slidingly receive the ferrule holder and a rear portion terminating a fiber optic cable that includes the optical fiber, and an inner housing configured to fixed coupled with the ferrule housing. The ferrule is configured to terminate the optical fiber. The ferrule holder, the ferrule housing, and the inner housing are configured to be rotatably fixed to one another. The ferrule holder is configured to slide axially relative to the inner housing.

A floating optical fiber connector interface generally includes a retention bracket, a translating socket slidingly associated with the retention bracket, and a biasing element positioned between the retention bracket and the translating socket. A tab portion may permit translation of the translating socket with respect to the retention bracket, and an aperture configured to receive a carriage optical fiber connector. The translating socket may translate with respect to the retention bracket within a plane and may further translate in the insertion direction, and the biasing element may resist translation of the translating socket. An alignment plate may be configured to align an instrument interface for connection to a carriage, including a telescoping standoff operable to position the plate at a first position in which the plate is spaced apart from the carriage and to position the plate at a second position in which the plate is adjacent to the carriage.

Systems and methods are provided herein that generally involve measuring a prostate or other object. In some embodiments, a finger clip having a roller ring or wheel rotatably mounted thereto is disposed within an inflatable membrane. The roller ring can include a measurement pattern positioned opposite to optical fibers configured to receive light reflected from the measurement pattern. A user can put on the finger clip, position the membrane in proximity to a rectal wall overlying a prostate, and inflate the membrane. As the user slides their finger across the inside of the membrane, which is pressed against the rectal wall, the roller ring can rotate with respect to the fibers such that the fibers move relative to the measurement pattern. A controller can sense light reflected through the fibers from the reference pattern and calculate or estimate various attributes of the prostate based on the reflected light.

The present disclosure relates to a matched pair detachable connector for high fiber count applications where the configuration of the connector maintains optical fiber alignment and ferrule alignment during assembly of the connector.

A micro-optical connector holder with an integrated mating system for an optical assembly, typically on a modem PCBA. The integrated mating system is used to hold the micro-optical connectors together during assembly and to apply constant pressure keeping the connectors fully mated. The invention also uses a spring-pin mechanism to keep the holder lid and connectors in place without the use of screws or glue to make assembly easier. The integrated mating system allows the micro-optical connectors to be easily installed and uninstalled for manufacturing and testing purposes. The connector plugs and connector receptacles are aligned and secured by the integrated connector holder.

The present invention discloses a fiber optic connector comprises: a ferrule assembly; a spring seat provided behind the ferrule assembly; and a spring provided between the ferrule assembly and the spring seat. The spring seat has a receiving chamber having an insertion port through which a portion of the ferrule assembly is inserted into the receiving chamber; wherein the ferrule assembly is pre-assembled into the receiving chamber of the spring seat in a way that the ferrule assembly is held to be movably engaged with the spring seat. The spring is fitted and compressed in the receiving chamber. As a result, the ferrule assembly, the spring seat and the spring are pre-assembled into an integral assembly before being inserting into a connector housing. All components of the connector except for the housing may be smoothly pulled through a small long pipe as a whole. After being pulled through the pipe, all components of the connector except for the housing may be easily and quickly inserted into the housing as a whole at one time.

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 connection, and a back body for supporting the ferrule springs. A removable inner front body for polarity change is disclosed. A multi-purpose rotatable boot assembly for polarity change is disclosed. The multi-purpose boot assembly can be pushed and pulled to insert and remove the micro connector from an adapter receptacle.

The present invention provides a spring bias that is particularly suited for use to preload a low profile ferrule of an optical connector. In accordance with the present invention, an axial preload is applied to a connector ferrule by a spring structure provided external of the connector. In one embodiment, spring structure is provided outside a plurality of optical fiber connectors, which provides axial preload of multiple ferrules. Each ferrule could be of the type that supports a plurality of optical fibers of a fiber cable. In one embodiment, the spring bias is effected by a planar flexure external of the connector. The ferrule is coupled to the planar flexure with its longitudinal axis through the center of the planar flexure. The planar flexure is structured with flexure members in a plane that are configured to not create any torque load on the ferrule, or if torque loading is present, insignificant torque load to cause misalignment of the ferrule, when the flexure flexes out of its nominal plane to create an axial preload on the ferrule. In another embodiment, a common yoke is applied to bias planar flexures against a plurality of ferrules, wherein a planar flexure is coupled to each ferrule connector. In a further embodiment of the present invention, instead of using planar flexures, a yoke is provided to apply an axial preload to all ferrule connectors coupled to the yoke, by means of a coil spring applied to center of the yoke, external of the ferrule connectors.
