Abstract
An optical fiber transition assembly comprises a cable having a first terminal end from which extends an optical fiber. A furcation tube is also provided, having a second terminal end near the first terminal end of the cable into which the optical fiber of the cable is received. A polymeric transition element surrounds the first and second terminal ends to protect and secure the optical fiber in transition from the cable to the furcation tube, the polymeric transition element being configured to be retained in an entry port of an enclosure.
Claims29
An optical fiber transition assembly comprising:
- a cable having a first terminal end from which extends an optical fiber;
- a furcation tube having a second terminal end near said first terminal end of said cable into which said optical fiber of said cable is received;
- and
- a polymeric transition element surrounding said first and second terminal ends to protect and secure said optical fiber in transition from said cable to said furcation tube, said polymeric transition element being configured to be retained in an entry port of an enclosure.
An optical fiber assembly comprising:
- an optical fiber cable having a first terminal end from which extends an optical fiber;
- an enclosure defining an entry port through which said optical fiber passes into an interior thereof;
- and
- a transition element surrounding said first terminal end of said optical fiber cable to protect and secure said optical fiber in transition from said cable to said interior of said enclosure, said transition element configured to be retained at said entry port such that transition element is maintained in position.
A transition element for transition of an optical fiber from an optical fiber cable to a furcation tube, said transition element comprising:
- a plurality of transition sections attached together;
- each of said transition sections having an axis along which extends a first wider groove and a second narrower groove which respectively form a larger opening at a first end of said transition element and a smaller opening at a second end of said transition element;
- and
- said larger opening being configured for receipt of said optical fiber cable and said smaller opening being configured for receipt of said furcation tube.
A method of providing a transition of an optical fiber from an optical fiber cable to a furcation tube, said method comprising:
- providing a transition element having an axis along which extends a larger opening from a first end of said transition element and a smaller opening from a second end of said transition element, a furcation tube inserted into said smaller opening;
- removing a selected portion of an outer sheath of said optical fiber cable to expose said optical fiber;
- feeding said optical fiber through said larger opening and into said furcation tube;
- and
- pushing a portion of remaining outer sheath of said optical fiber cable into said larger opening.
