Abstract
A pipe section for coupling to one or more pipe sections in order to form an elongate tubular. The pipe section has an optical fiber extending along a longitudinal axis of the pipe section and a waveguide disposed near one end of the pipe section and is in optical communication with the optical fiber to guide light in a plane substantially perpendicular to the longitudinal axis.
