Composite active optical cables
View Patent ↗Composite active optical cables are provided. An active optical cable may include a plurality of optical fibers and one or more insulated electrical conductors. In some instances, the optical fibers may be positioned within a microtube. Additionally, in some instances, the electrical conductors may include stranded conductors. A jacket may also be formed around the optical fibers and the electrical conductors. A first optical to electrical converter may be positioned at a first end of the cable, and a second optical to electrical converter may be positioned at a distal end of the cable. Further, the conductors may be configured to carry a power signal from the first end of the cable to the distal end of the cable to power the second optical to electrical converter.
1. An active optical cable, comprising:

a first optical to electrical converter positioned at a first end of the cable; and
a second optical to electrical converter positioned at a distal end of the cable,
wherein the at least one conductor is configured to carry a power signal from the first end of the cable to the distal end of the cable to power the second optical to electrical converter.
2. The cable of claim 1 , wherein the at least one insulated electrically conductor comprises three conductors that each have approximately the same diameter.
3. The cable of claim 1 , wherein the power signal is further configured to power a client device connected at the distal end of the cable.
4. The cable of claim 1 , wherein the at least one conductor comprises a stranded conductor.
5. The cable of claim 1 , wherein the at least one conductor comprises either two or three conductors.
6. The cable of claim 1 , wherein the at least one conductor comprises two 24 gauge conductors or two 26 gauge conductors.
7. The cable of claim 1 , wherein the at least one conductor comprises three 32 gauge conductors.
8. The cable of claim 1 , wherein the plurality of optical fibers comprises four optical fibers.
9. The cable of claim 1 , wherein the cable has a diameter of less than approximately three millimeters.
10. An active optical cable, comprising:
at least one optical fiber configured to carry one or more communications signals;
at least three individually insulated conductors, each of the conductors having approximately the same diameter;
a jacket formed around the at least one optical fiber and the at least three conductors;
a first optical to electrical converter positioned at a first end of the cable; and
a second optical to electrical converter positioned at a distal end of the cable,
wherein the at least three conductors are configured to carry a power signal from the first end of the cable to the distal end of the cable to power the second optical to electrical converter and a client device connected to the distal end of the cable.
11. The cable of claim 10 , wherein the at least one optical fiber comprises a plurality of optical fibers that are loosely and independently positioned within a microtube that permits shifting of the optical fibers while preventing crossover of two or more of the optical fibers during bending.
12. The cable of claim 10 , wherein each of the at least three conductors comprises a plurality of strands of electrically conductive material.
13. The cable of claim 10 , wherein the at least three conductors comprise 32 gauge conductors.
