Abstract

Described is a furcation kit for a multiple optical fiber cable. The cable end is secured by a mechanical compression fitting and optical fibers are routed into one or more plugs each having a plurality of single optical fiber passages. A protective shell is mechanically secured around the area of furcation. The kit eliminates the need for epoxies, and capsulants, and thereby decreases the time needed for installation of the furcations.

Claims

1. Apparatus for furcating a multiple optical fiber cable comprising:

a. securing means for securing one end of a multiple optical fiber cable;

b. an optical plug having a plurality of single optical fiber passages;

c. an optical jack member having a port receiving the optical plug; and

,

d. a support member mounted between the securing means and the optical jack member.

2. Apparatus as recited in claim 1, wherein the securing means comprises a rigid tubular wedging member having an inner diameter tapering from wide to narrow toward the support member, a sheath clamp within the wedging member having an outer diameter tapering from wide to narrow toward the support member, and urging means for urging the sheath clamp toward the support member to constrict the sheath clamp around a multiple optical fiber cable inserted therein.

3. Apparatus as recited in claim 1, wherein the optical jack member is a disc having a plurality of optical plug receiving ports in the outer periphery thereof.

4. Apparatus as recited in claim 2, wherein the optical jack member is a disc having a plurality of optical plug receiving ports in the outer periphery thereof.

5. Apparatus as recited in claim 2, wherein the urging means comprises a perforated block having an external screw thread engaging an internal screw thread in the tubular wedging member.

6. Apparatus as recited in claim 4, wherein the urging means comprises a perforated block having an external screw thread engaging an internal screw thread in the tubular wedging member.

7. Apparatus as recited in claim 1, further comprising plug securing means for preventing separation of the optical plug in a direction parallel to the single optical fiber passages when such optical plug is received in the optical jack.
