Abstract
A section of pipe for well operations has a cylindrical fiber composite pipe body and a pair of metallic end fittings. The end fittings differ from each other in that they are provided with mating key features to ensure proper angular or rotational alignment between two abutting sections of pipe. Each pipe is also provided with an optical fiber for data transmission. A fiber optic coupling is located at each end of the optical fiber for sending and receiving data transmissions via optical signals. Multiple strings of pipe are abutted end to end to complete both mechanical and data interfaces. At the junction of each pair of adjacent pipes, the end fittings axially and rotationally align. The flanges of the end fittings are fastened together with bolts such that data transmission takes place between the optical fibers.
