Apparatus and methods for furcating fiber optic cables
View Patent ↗Methods and apparatus for furcating fiber optic cables are provided. In some embodiments, a molded furcation tube array is generated by compressing rearward end portions of a plurality of furcation tubes together, and heating at least a portion of the rearward end portions to form a molded portion of the furcation tube array. Reinforcing filaments can be bonded into and/or throughout the molded portion. The molded portion can have internal chambers in communication with separate furcation tubes of the furcation tube array, in which optic fibers can be slidably retained, and the molded portion can be fixedly coupled to a housing, which in turn, can be coupled to a cable trunkline. Optic fibers can piston or slide longitudinally within the trunkline housing and molded portion.
1. A method of constructing a cable assembly comprising:
arranging a plurality of furcation tubes in an array and compressing the furcation tubes together at a heating portion;
inserting pins into the furcation tubes in the heating portion prior to heating the heating portion; and
heating the heating portion to deform the furcation tubes and removing the pins from the heating portion after heating the heating portion, and wherein during heating the heating portion reinforcing filaments disposed within the furcation tubes are bonded into tube jackets of the furcation tubes in the heating portion, and wherein the plurality of furcation tubes in the array bond together in the heating portion to form a molded portion of the array.
2. The method of claim 1 further comprising threading optic fibers through chambers in the molded portion of the array, and pushing the optic fibers through to an unmolded portion of the array.
3. The method of claim 2 further comprising inserting the molded portion of the array into a housing, and fixedly coupling the molded portion of the array to the housing using an adhesive.
4. The method of claim 1 wherein compressing the furcation tubes together comprises binding the furcation tubes under pressure using a tape.
