US 2026/0046035 A1 · WIRED LIGHT FIDELITY FOR UNDERWATER COMMUNICATION

Abstract

The described technology facilitates improved communication that can be well-suited for communication in an underwater environment. For example, the concept of wired LIFI (w-LIFI) is introduced. A conduit or cable can have a core layer composed of air (e.g., any gas or gas mixture) that, along with a cladding layer comprising a highly reflective material, operates as a medium for EM signals. Thus, over-the-air wireless communication techniques, such as LIFI, can be adapted for wired transmission. The associated w-LIFI cable is lighter in weight and/or cheaper to produce, install, maintain or repair, and operate in comparison to systems that rely on fiber optic cable, which typically has a solid core of highly refined glass fibers that are heavy and fragile.

Dependent claims

A lightguide device, comprising:

a conduit configured to operate as an underwater transport medium for electromagnetic radiation (EMR) signals, the conduit comprising:
an outer layer comprising a first material that is flexible according to a flexibility criterion, is adapted to resist corrosion when immersed in water with respect to a non-corrosion criterion, and is adapted to withstand a hydrostatic pressure above a defined threshold;
an intermediate cladding layer comprising a second material configured to clad a reflective material to an inner surface of the outer layer;
and
a core layer composed of a fluid that operates as a propagation medium for the EMR signals that are propagated from a first end of the conduit through the fluid to a second end of the conduit via interactions with the reflective material.
