Fiber-optic strength member components for use in outer strength member layers
A cable containing at least one optical fiber in a strength member and methods for manufacturing the strength member and cable are provided. A cable may include a cable core and armor wire strength members that surround the cable core. One of the armor wire strength members that surround the cable core contains an optical fiber.
1. A cable comprising:
a cable core; and
a plurality of armor wire strength members that surround the cable core, wherein a first armor wire strength member of the plurality of armor wire strength members comprises a grooved interior space that houses a first optical fiber, wherein the grooved interior space is disposed within a channel in the first armor wire strength member, and wherein the grooved interior space is isolated within the channel via a cap shaped to fit into the channel and cause the first armor wire strength member to have a circular cross-section.
2. The cable of claim 1 , wherein the first armor wire strength member is disposed among an outermost periphery of the plurality of armor wire strength members.
3. The cable of claim 1 , wherein the cable comprises a marine cable and wherein the plurality of armor wire strength members are disposed within a shielding layer that surrounds the cable core.
4. The cable of claim 1 , wherein the grooved interior space is filled with a gas.
5. The cable of claim 4 , wherein the gas comprises air.
6. The cable of claim 1 , wherein the grooved interior space is filled with a silicon polymer.
7. The cable of claim 1 , wherein the grooved interior space is filled with an ultraviolet-curable polymer.
8. The cable of claim 1 , wherein the grooved interior space comprises a first longitudinal channel first armor wire strength member.
9. The cable of claim 8 , wherein the first armor wire strength member comprises a second grooved interior space that houses a second optical fiber, wherein the second grooved interior space comprises a second longitudinal channel in the wire.
10. The cable of claim 1 , wherein a second armor wire strength member of the plurality of armor wire strength members does not comprise a grooved interior space.
11. A cable comprising:
a first plurality of wire members disposed circumferentially at a first radial distance from a center of the cable, wherein at least one wire member of the first plurality of wire members comprises a first grooved interior space that houses a first optical fiber, wherein the first grooved interior space is disposed within a channel of the at least one wire member of the first plurality of wire members, and wherein the first grooved interior space is isolated within the channel via a cap shaped to fit into the channel and cause the least one wire member to have a circular cross-section; and
a second plurality of wire members disposed circumferentially at a second radial distance from the center of the cable, wherein the second radial distance is greater than the first radial distance, wherein at least one wire member of the second plurality of wire members comprises a second grooved interior space that houses a second optical fiber.
12. A cable comprising:
a cable core; and
a plurality of armor wire strength members that surround the cable core, wherein a first armor wire strength member of the plurality of armor wire strength members comprises a grooved interior space that houses a first optical fiber, wherein the grooved interior space is disposed within a single wire having a channel, and wherein the grooved interior space is isolated within the channel via a plug wire that has a fully rounded profile.
