Title: Add/drop multiplexer routing signals according to wavelength

Abstract: An add/drop multiplexer comprises passive optical components for wavelength division multiplexing. The multiplexer allows signals passing along fibers of a main trunk between terminal stations to be dropped to and added from a spur station, allowing a reduced number of spur fibers to be used since signals are routed between trunk fibers and spur fibers according to carrier wavelength.
