摘要:
Bi-directional tap assemblies for two-way fiber topologies are disclosed. The assembly includes a fiber-optic cable having a cable optical fiber adapted to carry bi-directional optical signals and that is preterminated at a mid-span location to form at least one first cable fiber end and at least one second cable fiber end. First and second tether fibers are respectively spliced to the first and second cable fiber ends. In one version of the assembly, the tether fibers are contained in respective first and second tether covers to form first and second tethers that extend in opposite directions from the tap point. In another version of the assembly, the tether fibers are bend-insensitive fibers and are contained in a single tether cover to form a single tether. The tether fibers bend back on themselves within the tether cover and terminate at a common end of the tether, thereby allowing both downstream and upstream optical signals to be accessed at the tether end. The single tether is configured to be translateable along the fiber-optic cable by allowing the bend locations in the bend-insensitive fibers to change as the tether is translated.

A fiber optic plug assembly of a fiber optic connector assembly is provided and generally includes a fiber optic plug mounted upon an end of a fiber optic cable; a pre-molded boot placed over the fiber optic plug and the fiber optic cable; and a crimp band mated over the pre-molded boot to secure the boot to the fiber optic cable; wherein the fiber optic plug assembly is operable to mate to a fiber optic receptacle. The plug assembly eliminates the need for an overmolded boot. Further, the present invention eliminates the need to perform a heat shrink between the buffer tube and crimp body through the internal O-ring. The plug assembly meets the standards of GR-3120-CORE while at the same time providing a simpler hardware package that can be assembled with ordinary connectorization tools.

摘要:
A cable assembly comprising a fiber optic cable having a ribbon stack therein, at least one network access location for accessing the ribbon stack, and a bonding fillant for locking an uncut portion of the ribbon stack to the cable at the network access location to prevent ribbon stack translation and rotation at the network access point relative to the tubular component. A method for eliminating optical fiber translation and rotation at a predetermined position within a fiber optic cable comprising providing a cable, forming an access location, filling exposed cable portions with a fillant, flowing the fillant, and curing the fillant to bond a length of the ribbon stack within the cable.

A method of facilitating mid-span access of an optical fiber ribbon cable, and the resulting cable, that provides for redeveloping and/or modifying excess ribbon length with the accessed cable structure. The method includes the use of a form placed within the cable structure that controls the excess ribbon length. The method may further include the reconstitution of severed strength members.

A bent optical fiber coupler (100) that employs at least one optical fiber (10) is disclosed. The coupler includes a curved optical fiber guide channel (200) having a strong curve. The optical fiber(s) held within the optical fiber guide channel have a bend corresponding to the guide channel curve. The fiber end portions are optionally disposed within a straight fiber guide (160) at a coupler input/output end, which is preferably configured to have a standard connector geometry. Use of nanostructured fibers for the at least one optical fiber allows for strong bends having tight radii of curvature without imparting significant attenuation. Coupler assemblies that include the coupler optically coupled to at least one opto-electronic device (310) are also disclosed.

A method of assembling an optical fiber connector includes the steps of providing a ferrule with an internal through passage, and using a gas for treating a surface of the internal through passage to enhance a bonding capability of the surface. Adhesive is introduced into at least a portion of the internal through passage and at least one optical fiber is secured to the surface of the internal through passage by the adhesive. Another method includes the steps of providing the ferrule with an internal through passage including a shoulder, a window that extends through a side surface, and a cap having at least a portion inserted into the window. Adhesive is introduced into at least a portion of the internal through passage and is in engagement with the shoulder for providing an axial stop for securing at least one optical fiber with respect to the internal through passage.
