The present disclosure relates to a ferrule-less fiber optic connector including a connector body having a front end. The ferrule-less fiber optic connector can include a plurality of optical fibers that extend through the connector body. The optical fibers can have having free end portions at the front end of the connector body that are not supported by a ferrule or by ferrules. In one example, the ferrule-less fiber optic connector can be a duplex fiber optic connector. Transceiver modules and components are also disclosed.

A sealing enclosure is configured to connect to a mating enclosure. The sealing enclosure loosely receives a connector within a connector volume so that the connector, which may be of a standard type used in electronic or optic data transmission, may be displaced within a plug face at the forward end of the connector volume. The connector may compensate variations in the position of a mating connector with respect to the mating enclosure. The sealing enclosure allows to seal off the connector volume and engage the sealing enclosure with a mating enclosure in a single motion. This is affected by having a cable seal interposed between an inner body and an outer body. If the outer body is moved forward to engage the mating connector, the cable seal is squeezed between the cable and the inner body sealing off the connector volume at the rearward end of the inner body.

Example fiber optic connector systems have rugged, robust designs that are environmentally sealed and that are relatively easy to install and uninstall in the field. Some connector systems can be configured in the field to be compatible with different styles of fiber optic adapters. Some connectors include a first seal (90) on a release sleeve; and a second seal (88) between the release sleeve and a connector body. Other connectors include a seal (139) and a flexible latch (136) on a connector. Other connectors include a protective structure (228, 328, 428) that mounts over the fiber optic connector. Other connectors include a protective outer shell (528, 860) and a sealing and attachment insert (570, 570A, 876). Other connectors include a protective outer shell (728) and a fastener (780).

In accordance with the following description, an optical communication connector includes a ferrule having retractable alignment pins that are actuable between an extended position and a retracted position. For example, the connector may include an inner housing assembly having optical fibers and an outer housing positioned over the inner housing assembly. The outer housing is shaped to be removable from the inner housing assembly, which has a movable pin clamp mechanically coupled to alignment pins for aligning the connector with another connector. The pin clamp may be slid from a first position (corresponding to a male gender) to a second position (corresponding to a female gender). Separately or in combination with changing gender, the polarity of a communication connector may be changed due to its inclusion of an asymmetric polarity-changing feature that is actuable by an installer to change a polarity of the communication connector. Such a feature may actuated by being moved from a first position to a second position relative to the communication connector.

A ferrule-based fiber optic connectors having a connector assembly with a ferrule insertion stop for limiting the insertion of a ferrule into a ferrule sleeve are disclosed. In one embodiment, the fiber optic connector comprising a connector assembly, ferrule insertion stop, a connector sleeve assembly and a female coupling housing. The connector assembly comprises a ferrule and a resilient member for biasing the ferrule forward and the connector sleeve assembly comprises a housing and a ferrule sleeve, where the ferrule of the connector assembly is at least partially disposed in the ferrule sleeve when assembled. The ferrule insertion stop limits the depth that the ferrule may be inserted into the ferrule sleeve.

A multi-fiber ferrule has a main body with a top portion and a bottom portion, the top portion includes a top cut-out therein to form a first forward facing surface to engage a housing of a fiber optic connector. The top cut-out extends rearwardly from the front end. The bottom portion also has a bottom cut-out portion forming a second forward facing surface to engage the housing of the fiber optic connector, the bottom cut-out also extending rearwardly from the front end. The multi-fiber ferrule also includes an end face at a front end of the main body, and a rear face at a rear end of the main body. There is a rear central opening that extends into the main body from the rear end face and configured to receive at least three optical fibers.

A package for an optical fiber includes: a base portion; a plurality of protruding portions that protrude from a flat surface of the base portion, are arranged along an outer periphery of the base portion, and are configured so that an optical fiber including a connector mounted to at least one end thereof is wound along a part of an outer periphery of each of the protruding portions; a mounting portion to which the connector of the optical fiber is to be mounted; and a plurality of fall-off preventing portions that are formed integrally with the base portion and capable of restricting a position of the optical fiber to be wound over the plurality of protruding portions.

A port tracer including a housing, a light guiding tunnel, and a light guide cover. The housing has a first side and a second side opposite to each other and a third side connected to the first side and the second side. A first opening and a second opening are located on the first side and the second side respectively. The light guiding tunnel is disposed inside the housing. The light guiding tunnel has a first light entrance-exit and a second entrance-exit that face the first side and the second side respectively. The light guide cover is detachably connected to the first opening. The light guide cover covers the first light entrance-exit. The third side has a third opening. A part of the light guide cover is located inside the housing and opposite to the third opening.

Fiber optic connectors, cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a multifiber ferrule. The housing comprises a longitudinal passageway between a rear end and a front end, and a rear portion of the housing comprises a keying portion and at least one locking feature integrally formed in the rear portion of the housing.

Connector assemblies are described herein. For example, a connector assembly including: a housing configured to accept a first ferrule and a second ferrule. The connector assembly may also have a push/pull clip that is configured to depress a protrusion that rotates down a connector device to remove the connector assembly from an adapter. The push/pull clip is integrated with a cable boot assembly that allows a user to apply a distal force to remove or insert the connector assembly into the adapter housing. The push/pull clip is configured for use to release a MPO and LC connector type from an adapter.
