Solution Overview

Problem

Conventional active optical cables require each device to power its respective optical to electrical (O2E) interface, limiting the ability to power client devices remotely and restricting data transfer rates due to the use of copper conductors.

Innovation Solution

A composite active optical cable incorporating optical fibers and conductors, with O2E interfaces at both ends, allows power transmission from one end to the other, enabling remote powering of client devices and supporting higher data transfer rates through the use of optical fibers and insulated conductors.

AI summary

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.
