An amplified optical link having a fault-protection capability that is based, at least in part, on the ability to selectively and independently power up and down different groups of optical amplifiers within the link. In an example embodiment, the optical link is implemented using an optical fiber cable having an electrical power line and arrays of optical amplifiers connected between successive optical fiber segments to form a plurality of disjoint groups of parallel optical paths between the ends of the optical fiber cable. The electrical power line is operable to selectively power, as a group, the optical amplifiers of at least some of the disjoint groups. In various embodiments, different optical paths can be implemented using different respective strands of a single-core optical fiber, different respective cores of a multi-core optical fiber, and/or different respective sets of spatial modes of a multimode optical fiber.

The present disclosure provides advantageous cable assemblies (e.g., hybridized cable assemblies), and improved methods/systems for using the same. More particularly, the present disclosure provides improved systems/methods for the design and use of hybridized cable assemblies configured to facilitate the transfer of data and power. The present disclosure provides an advantageous hybridized cable assembly that is configured and adapted to transfer data and power across some length of a hybrid cable. An advantageous hybridized cable assembly can be configured to function with available hardware. Certain embodiments can utilize Power over Ethernet (PoE) technology to provide power to the hybridized cable assembly and subsequently to the end device. An exemplary hybridized cable assembly can transfer a combined transmission across some length of the hybridized cable assembly. The hybridized cable assembly can perform alterations to the incoming transmissions prior to outputting the combined transmission to a desired device.
