Abstract
An optical cable includes a main body and a termination segment extending from an end of the main body. The main body includes middle portions of optical fibers. The termination segment includes end portions of the optical fibers and multi-fiber connectors attached to the end portions of the optical fibers. The multi-fiber connectors are staggered along a length of the termination segment.
Claims19
An optical cable comprising:
- a plurality of optical fibers, the plurality of optical fibers comprising multiple bunches of optical fibers;
- an outer layer covering a first length portion of the plurality of optical fibers, a second length portion of the plurality of optical fibers extending beyond an edge of the outer layer;
- and
- a plurality of multi-fiber connectors, each multi-fiber connector of the plurality of multi-fiber connectors being coupled to a respective bunch of optical fibers, wherein the plurality of multi-fiber connectors is arranged at positions distributed along a length of a termination segment of the optical cable, the termination segment extending from the edge of the outer layer, wherein, at a first position closest to the edge of the outer layer, only one multi-fiber connector of the plurality of multi-fiber connectors is arranged, and wherein, at a second position farthest from the edge of the outer layer, two or more multi-fiber connectors of the plurality of multi-fiber connectors are arranged such that a total number of multi-fiber connectors per cross sectional area of the termination segment increases from the edge of the outer layer towards an end of the optical cable along the length of the termination segment.

An optical cable comprising:
- a main body comprising middle portions of a plurality of optical fibers;
- and
- a first termination segment extending from an end of the main body, the first termination segment comprising:
- end portions of the plurality of optical fibers, each end portion being continuous with a respective middle portion;
- and
- a plurality of multi-fiber connectors, each multi-fiber connector of the plurality of multi-fiber connectors being attached to respective end portions of the plurality of optical fibers, wherein the plurality of multi-fiber connectors is arranged at positions distributed along a length of the first termination segment, wherein, at a first position closest to the main body, only one multi-fiber connector of the plurality of multi-fiber connectors is arranged, and wherein, at a second position farthest from the main body, two or more multi-fiber connectors of the plurality of multi-fiber connectors are arranged such that a total number of multi-fiber connectors per cross sectional area of the termination segment increases from the end of the main body towards an end of the optical cable along the length of the first termination segment.

A method of manufacturing a pre-terminated optical cable, the method comprising:
- exposing a plurality of tubes by removing an outer jacket of an optical cable from a termination segment of the optical cable, the termination segment extending from a main body of the optical cable;
- setting a length of a first tube of the plurality of tubes to a first length;
- setting respective lengths of a second tube and third tube of the plurality of tubes to a second length, the second length being greater than the first length;
- setting respective lengths of the remaining tubes of the plurality of tubes to lengths greater than the first length;
- terminating optical fibers of the plurality of tubes with multi-fiber connectors, wherein a total number of multi-fiber connectors per cross sectional area of the termination segment increases from an end of the main body towards an end of the optical cable along the length of the termination segment;
- and
- binding the plurality of tubes and the multi-fiber connectors in the termination segment with a wrapper.
