A strain relief boot and a fiber optic cable assembly are described. The strain relief boot has a first conduit made of at least a first material. The first conduit has a front segment and a rear segment. The rear segment includes at least one discontinuity to make the rear segment more flexible than the front segment. The rear segment also includes at least one projection extending outwardly from the rear segment at a location adjacent to the at least one discontinuity. The strain relief boot also has a second conduit made from at least a second material that is less rigid than the first material. The second conduit at least partially surrounds at least the rear segment of the first conduit and extends rearwardly of the first conduit.

A method of removing a tight buffer coating from an optical fiber involves positioning an end section of the optical fiber next to an end of a tube, with at least a portion of the the end section including a primary coating and the tight buffer coating. The tube has an inner diameter greater than an outer diameter of the primary coating and an outer diameter less than an outer diameter of the tight buffer coating. The method also involves applying energy to heat the tight buffer coating, inserting the end section of the optical fiber into the tube so that the tight buffer coating contacts the end of the tube, and advancing the end section of the optical fiber along the tube. The tube removes the tight buffer coating from the primary coating as the end section of the optical fiber is advanced.

Methods of removing coating material from optical fibers

A fiber optic connector is described herein. The fiber optic connector includes a ferrule for supporting at least one optical fiber of a fiber optic cable, a ferrule holder from which the ferrule extends, a housing in which the ferrule holder is received, and a strain relief device at least partially located within the housing. The strain relief device has at least one resilient clamping member selectively applying a compressive force to at least a portion of the fiber optic cable. The strain relief device also has an actuator at least partially surrounding the ferrule holder, and used to place the at least one resilient clamping member into compressed contact with the fiber optic cable, thus retaining the fiber optic cable within the housing.

Methods are provided for validating the continuity of one or more optical fibers upon which a fiber optic connector is mounted. Typically, the fiber optic connector is mounted upon an optical field fiber by actuating a cam mechanism to secure the optical field fiber in position relative to an optical fiber stub. If subsequent testing indicates that the continuity of the optical field fiber and the optical fiber stub is unacceptable, the cam mechanism can be deactuated, the optical field fiber can be repositioned and the cam mechanism can be reactuated without having to remove and replace the fiber optic connector. In order to determine if continuity has been established between the optical field fibers and respective optical fiber stubs, a method is also provided that introduces light into at least one of each pair of optical field fibers and optical fiber stubs and that only secures the position of each optical field fiber relative to the respective optical fiber stub once the glow associated witheach pair of optical field fibers and optical fiber stubthe optical field fiber and the optical fiber stubdissipates, which dissipation indicates the establishment of continuity. An improvedmultifiberconnector and installation tool are also provided to facilitate the establishment and validation of the continuity ofoptical field fibers and optical fiber stubsthe optical field fiber and optical field stubin order to reduce the time and cost required to connectorize opticalfield fibersfiberin the field.

Apparatus and methods for stripping tight-buffered optical fibers are disclosed. The apparatus is configured to perform one or more of the functions of stripping a tight buffer layer, removing a coating layer, and cleaving the fiber, in a single motion.

Stripping apparatus and methods for optical fibers

Methods, cleavers, and packagings for cleaving an optical fiber using an abrasive medium are disclosed. In one embodiment, a bladeless cleaver includes a body having an arcuate exterior surface, which may be provided in one embodiment by an exterior surface of a tool or toolkit, such as, but not limited to, a consumables kit or other packaging. A cleaver structure is disposed on the body such that a space between the arcuate exterior surface of the body and the cleaver structure is configured to receive a portion of the optical fiber to be cleaved. The cleaver structure comprises an abrasive medium carrier that is configured to be actuated to place the abrasive medium in contact with the portion of the optical fiber to create a flaw in the portion of the optical fiber. In another embodiment, the portion of the optical fiber may be positioned directly along the arcuate exterior surface of the body.

An optical fiber stripper that may cooperate with an optical fiber handler for stripping one or more coating from an optical fiber is disclosed. The stripper is used as a part of a termination system for preparing the optical fiber for an optical connection, thereby providing the craft with a simple, reliable, and easy termination of the optical fiber. By way of example, the stripper cooperates with an optical fiber handler having an optical fiber secured therein for preparing the end of the optical fiber for a mechanical splice in a fiber optic connector.

Methods, cleavers, and packagings for cleaving an optical fiber using an abrasive medium are disclosed. In one embodiment, the bladeless cleaver includes a body having a flexible tongue configured to receive an optical fiber. The flexible tongue is further configured to provide an arcuate surface to bend a portion of the optical fiber. The bladeless cleaver in this embodiment also includes a cleaver structure attached to the body that comprises an abrasive medium carrier configured to support an abrasive medium. The abrasive medium carrier is configured to be actuated to place the abrasive medium in contact with the portion of the optical fiber to create a flaw in the portion of the optical fiber.

An optical fiber mechanical splice connector system that couples with a field fiber includes a connector body comprising a ferrule receiving portion, a pellet receiving portion and a support portion between the ferrule receiving portion and pellet receiving portion. The pellet receiving portion includes one or more engagement fingers connected at a first end to the support portion and extending away from the ferrule receiving portion to a second, free end adjacent a pellet receiving opening of a pellet receiving cavity at the pellet receiving portion. A ferrule is connected to the connector body at the ferrule receiving portion. A stub fiber is captured within the ferrule. The stub fiber extends from the ferrule into a fiber receiving cavity provided within the connector body for connecting with the field fiber. A fiber carrying pellet carries the field fiber. Inserting the fiber carrying pellet through the pellet receiving opening resiliently deflects the one or more engagement fingers thereby enlarging the pellet receiving opening such that the fiber carrying pellet is received by the pellet receiving cavity of the connector body.

An optical fiber handler for optical connector termination systems and other devices are disclosed herein.
