An optic fiber system for mounting in a rack, cassette and front plate are disclosed. A fiber optic cassette receives a pair of opposed rails on opposite inner surfaces of a housing. Catches on the fiber optic cassette comprise biased tabs which engage grooves within the rails thereby releasable securing the cassette into the housing. Catches may be provided at both ends of the cassette allowing the cassette to be inserted from either end of the housing. The cassette comprises removable front plate which is secured to it using a snap fit. The removable plate can be used either with the cassette or as a standalone within the housing.

A connector pack for an optical fiber enclosure has a plurality of connector slots each for receiving a respective connector on a cable. The connector pack has a first set of connector slots on a first side of a connector pack body and a second set of connector slots on a second side of the connector pack body. The first set of connector slots and the second set of connector slots each include a latch opening for receiving a latch of a respective connector. The latch opening of the first set of connector slots is offset with respect to the latch opening of the second set of connectors. According to some embodiments, the latch opening of the first set of connector slots is inverted with respect to the latch opening of the second set of connector slots.

An object is to be capable of housing an optical fiber that connects between components not to exceed a bending limit of the optical fiber in a housing of a pluggable optical module. A pluggable electric connector (11) is configured to be insertable into and removable from an optical communication apparatus (93). An optical output module (12) outputs an optical signal (LS1) and a local oscillation light (LO). An optical reception module (13) outputs a communication data signal (DAT) generated by demodulating using the local oscillation light (LO). A pluggable optical receptor (15) is configured in such a manner that optical fibers are insertable thereinto and removable therefrom. A first optical fiber (F11) is connected between the optical output module (12) and the pluggable optical receptor (15). A second optical fiber (F12) is connected between the optical output module (12) and the optical reception module (13). A third optical fiber (F13) is connected between the optical reception module (13) and the pluggable optical receptor (15). Optical fiber housing means winds extra lengths of the first to third optical fibers (F11 to F13) around a guide.

A fiber optic cable transition assembly for transitioning a plurality of optical fibers from a multi-fiber cable to a plurality of furcation tubes. The fiber optic transition assembly has a housing with a front opening and an internal passageway that is defined by a wall and a narrow region. The housing is adapted to receive epoxy adhesive. The fiber optic transition assembly has a boot that is positioned at least partially inside the housing for receiving the multi-fiber cable to provide strain relief to the plurality of optical fibers extending therethrough. The fiber optic transition assembly has a plug supported by the boot and retained by the housing to prevent epoxy adhesive from entering the multi-fiber cable.

A fiber optic connector has at least two optical fibers therein have end faces that are positioned such that they are directed in different directions. The end faces can be oriented relative to a key that is provided on a fiber optic connector housing that has a central opening in the main body of the fiber optic connector.

A method for manufacturing an optical fiber connecter includes preparing optical fiber including a glass fiber and a resin coating portion covering the glass fiber, mounting the optical fiber on a first optical fiber holder, adjusting an azimuth around a central axis for the optical fiber, bonding the glass fiber to the first optical fiber holder, mounting the glass fiber on a second optical fiber holder, bonding the glass fiber to the second optical fiber holder, and grinding end faces of the glass fiber and an the second optical fiber holder so that the end face of the glass fiber is flush with the end face of the second optical fiber holder.

An optical connector includes: a ferrule having a fiber hole into which an optical fiber is inserted and a guide hole into which a guide pin is inserted; a housing that accommodates the ferrule; and a biasing member disposed in the housing and applies to the ferrule a biasing force directed toward a side close to an opening portion of the housing in an axial direction of the guide hole, the biasing force having nonlinear characteristics.

An interconnect system is provided that involves pre-installing a connector housing an optical connector in an adapter and a ferrule of the same optical connector on a cable. The ferrule terminates one or more groups of optical fibers, and a ferrule push component is also pre-installed on the same group(s) of optical fibers. The connector housing is configured to receive and retain the ferrule and ferrule push component without being removed from the adapter to simultaneously form the optical connector and install the optical connector in the adapter. Embodiments such an interconnect system involving high fiber-count cables and related installation methods involving many optical connections are disclosed.

An optical connector assembly includes first and second optical ferrules. Each of the first and second optical ferrules includes a front portion extending forwardly from a rear portion. The rear portion includes a top side and a bottom side. The bottom side of the rear portion defines a recessed portion. The first and second optical ferrules mate with each other such that the front portion of each of the first and second ferrules is disposed in the recessed portion of the other one of the first and second ferrules. Discrete retainers are assembled to opposite ends of the mated first and second ferrules. Each of the retainers defines a resilient portion resiliently forcing the front portion of one of the first and second mated ferrules against the other one of the first and second optical ferrules.
