Abstract

In this paper we describe a structurally integrated optical transmitter beacon concept that consists of a side-scattering fiber that can conform to solid surfaces, such as the outer surface of a submersible Remotely Operated Vehicle (ROV), suitable for convenient deployment in underwater applications. By coupling a modulated optical signal from a laser diode into the fiber, an omnidirectional "beacon" is achieved. We demonstrate coarse Wavelength Division Multiplexing (WDM), illustrating that these beacons can transmit optical wireless data through several attenuation lengths in turbid water at aggregate data rates of up to 20 Mb/s.
