A gradual fiber cladding light stripper and its manufacturing method is disclosed to include an optical fiber that has a core, a cladding outside the core and an outer coating outside the cladding, the outer coating being removed by a preset cutting fixture to form a pre-stripping section, and a recoating section coated on the surface of the pre-stripping section at one time with a covering glue, the covering glue being irradiated and cured through a preset light curing device to form the recoating section with a gradual light stripping rate. The recoating section has a laser light input terminal with a relatively lower light stripping rate, and a laser light output terminal with a relatively higher light stripping rate.

Optical fiber coating stripping through relayed thermal radiation is disclosed. A heat source is provided that is configured to emit thermal radiation when activated. A relay system is provided that is configured to receive the emitted thermal radiation from the heat source and relay the emitted thermal radiation to a heating region. For example, the relay system may be configured to relay (i.e., re-direct) the thermal radiation to a concentrated heating region. The heat source and relay system are configured such that thermal radiation relayed by the relay system causes the temperature in the heating region to reach or exceed a vaporization or thermal decomposition temperature of a coating(s) of an optical fiber to be stripped. When an optical fiber is disposed in the heating region, and the heat source is activated, a coating(s) of the optical fiber decomposes thus stripping the coating(s) from the optical fiber.

A fiber optic cable assembly comprises first and second cable legs each including a tight buffer surrounding coated optical fibers, and a reduced thickness buffer connecting region, with cable leg being devoid of any surrounding jacket and any tensile strength member. A fiber optic cable assembly devoid of a tensile strength member mechanically coupled to a connector comprises a travel limiting feature that serves to limit travel of the ferrule and inhibit ferrule decoupling when tension is applied to a fiber optic cable.

A stripping tool configured to sequentially strip the layers of a cable, such as a fiber optic cable. The stripping tool includes multiple channels, each with a distinct role in stripping a layer of the fiber optic tool. The user sequentially moves the cable from channel-to-channel while operating the tool. At the conclusion of these operations the cable is appropriately stripped and ready for a subsequent operation.

The disclosure relates to a fiber optic connectors and sub-assemblies having a retention body for connectorizing a fiber optic cable along with fiber optic connectors and methods therefor. In one embodiment, the sub-assembly comprises a cable lock comprises a cable channel for receiving a fiber optic cable therethrough, and at least one strength member engagement surface. The retention body comprises an optical fiber channel for receiving an end portion of at least one optical fiber of the fiber optic cable therethrough, and at least one strength member engagement surface. The strength member engagement surfaces of the cable lock and the retention body are configured to cooperate with each other to receive and retain at least one strength member of the fiber optic cable. Other fiber optic connector sub-assemblies are also disclosed.

Fiber optic connector assemblies and method for assembling the same are disclosed. In one embodiment, a fiber optic connector assembly includes an optical fiber having an inner glass region, a polymer layer surrounding the inner glass region, and a windowed portion, wherein the inner glass region is exposed at the windowed portion. The fiber optic connector assembly further includes a connector body having a demarcation region at a first end, wherein the optical fiber is disposed within the connector body such that at least a portion of the windowed portion is positioned in the demarcation region, and the optical fiber is adhered to the connector body at the windowed portion. In another embodiment, the demarcation region includes an opening in the outer jacket that exposes the at least a portion of the windowed portion of the plurality of optical fibers and the optical fibers are adhered to a portion of the cable.

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.
