摘要： A ferrule boot for attachment to an optical fiber ribbon has a channel extending therethrough. The channel has at its distal end a first tapered lead-in section sized and dimensioned such that the optical fiber ribbon with the internal optical fibers stripped and exposed is insertable through the ferrule boot. The first tapered lead-in section is connected to a second tapered section, and the second tapered section prevents adhesives used to affix the optical fiber ribbon to a ferrule from wicking to the outside of the ferrule boot. The channel has a substantially straight section fitting intimately over the outside of the optical fiber ribbon to center and guide the exposed optical fibers to the center of the proximal end of the channel. In an embodiment, the ferrule boot also has a lip member disposed proximate to the proximal end of the channel to help seal the adhesive and ease insertion. Additionally, the lip may also prevent withdrawal of the optical fiber ribbon. In another embodiment, the ferrule boot also has a vent hole to allow air or other gases trapped in the ferrule boot cavity to vent to the ambient atmosphere.

摘要： Eccentricity of a optical fiber installed in a passageway of a ferrule is minimized by imposing a force on the end of the optical fiber projecting from the passageway at the ferrule end face to push the optical fiber to a desired position in the passageway, prior to curing an adhesive used for fixing the optical fiber in the passageway, so as to compensate for eccentricity of the passageway. In one embodiment, the force is imposed on the optical fiber by hanging a weight on the optical fiber. In another embodiment, the force is imposed on the optical fiber by using a pressurized jet of fluid. The point of application of the force, the magnitude of the force, and the viscosity of the adhesive are selected such that minimal optical fiber bending occurs, thereby assuring that the optical fiber is positioned at the desired position in the passageway for an appreciable distance from the ferrule end face along the passageway.

摘要： The splice housing assembly provides a non-activated mechanical splice that provides temperature compensation such that the resulting splice is substantially unaffected by temperature fluctuations, thereby permitting the splice housing assembly to be formed of relatively inexpensive materials, such as plastic. The splice housing assembly includes a splice tube having a first end that is attached to an end portion of the first optical fiber. The splice housing assembly also includes a temperature compensator disposed at least partially within the splice tube. The temperature compensator defines an opening through which the end portion of the second optical fiber extends. The first end of the temperature compensator is attached to the second optical fiber and the second end of the temperature compensator is attached is the splice tube. Advantageously, the temperature compensator and the splice tube are formed of different materials that are selected such that differences between the expansion and contraction of the splice tube and the optical fibers that arise as a result of temperature variations are at least partially offset by changes in length of the temperature compensator.

摘要： A pre-connectorized fiber optic distribution cable assembly includes a plurality of optical fibers and at least one mid-span access location along the length of the distribution cable. At least one of the optical fibers is accessed, terminated and then connectorized at the mid-span access location to an optical connector disposed within a receptacle. The mid-span access location, the accessed, terminated and connectorized optical fiber, the optical connector and at least a portion of the receptacle are encapsulated with a protective overmolded shell. A tether including at least one optical fiber connectorized at a first end of the tether is optically connected to the optical connector through the receptacle. A second end of the tether opposite the first end terminates in a network optical connection terminal, thereby compensating for a span length measurement difference between the actual location of the mid-span access and the desired location of the optical connection terminal.
