Abstract

A fiber optic cable includes at least one optical fiber and two electrical conductors. A mid-span connection point in the fiber optic cable has a configuration for attaching an opto-electronic component to the optical fiber and electrical conductors. At least one RF antenna is also included and is electrically connected to the opto-electronic component. A fiber optic cable assembly includes a plurality of optical fibers and at least two electrical conductors. An opto-electrical transceiver is in optical and electrical communication with the optical fibers and electrical conductors. An RF antenna is also in electrical communication with the opto-electrical transceiver.

Claims

1. A fiber optic cable assembly for connecting to one or more external opto-electrical components, comprising:

a single fiber optic cable having a length and a plurality of optical fibers disposed within and extending along at least a portion of the fiber optic cable;

at least two electrical conductors disposed within and extending along at least a portion of the fiber optic cable;

at least one mid-span connection point formed in the single fiber optic cable and traversed by at least one of the optical fibers;

at least one external optical fiber portion comprised of at least one portion of the at least one of the optical fibers made external to the fiber optic cable; and

external electrical conductor portions comprised of respective portions of the at least two electrical conductors made external to the fiber optic cable;

wherein said at least one external optical fiber portion and said external electrical conductor portions are configured to optically and electrically connect at least one of the one or more opto-electrical components to the fiber optic cable; and

wherein the one or more opto-electrical components are attached to the fiber optic cable by a tether.

2. The fiber optic cable assembly according to claim 1, wherein the mid-span connection point includes a connection point for an RF antenna that connects to the opto-electrical component when the opto-electrical component is connected to the mid-span connection point via said at least one external optical fiber portion and said at least two external electrical conductor portions.

3. The fiber optic cable assembly according to claim 1, further comprising at least one opto-electrical component connected to the at least one mid-span connection point via said at least one external optical fiber portion and said at least two external electrical conductor portions, wherein the at least one opto-electrical component includes an opto-electrical transceiver.

4. (Previously Presented The fiber optic cable assembly according to claim 1, wherein the tether is at least 6 inches long.

5. The fiber optic cable assembly according to claim 3, wherein, at one or more of the mid-span connection points, said at least one external optical fiber portion, said at least two external electrical conductor portions, and said at least one external opto-electrical component are secured to the fiber optic cable via an overmold.

6. The fiber optic cable assembly according to claim 1, wherein the tether further includes the at least one portion of the at least one of the optical fibers and the respective portions of the at least two external electrical conductors.

7. The fiber optic cable assembly according to claim 1, wherein the independent module further includes a jack configured to connect the one or more opto-electrical components to the at least one portion of the at least one of the optical fibers and the respective portions of the at least two external electrical conductors.

8. A fiber optic cable assembly for connecting to one or more external opto-electrical components, comprising:

a single fiber optic cable having a length and a plurality of optical fibers disposed within and extending along at least a portion of the fiber optic cable;

at least two electrical conductors disposed within and extending along at least a portion of the fiber optic cable; and

at least one mid-span connection point formed in the single fiber optic cable and traversed by at least one of the optical fibers, wherein at least one portion of the at least one of the optical fibers and respective portions of the at least two electrical conductors are made external to the fiber optic cable and configured to optically and electrically connect at least one of the one or more opto-electrical components to the fiber optic cable;

wherein the one or more opto-electrical components are provided in an independent module that is separable from the fiber optic cable assembly.

9. The fiber optic cable assembly according to claim 8, wherein the independent module further includes an outer housing to retain the one or more opto-electrical components.

10. The fiber optic cable assembly according to claim 8, wherein the independent module further includes a jack configured to connect the one or more opto-electrical components to the at least one portion of the at least one of the optical fibers and the respective portions of the at least two external electrical conductors.
