ABSTRACT:
An active tap for use in an optical multiple access network is disclosed. The tap comprises a semiconductor substrate on which the electronics associated with an active parallel path are fully integrated. These include optical detectors, amplifiers and light emitters formed using standard semiconductor fabrication techniques. A section of fiber, incorporated as an integral part of the tap structure, is provided with a pair of longitudinally spaced discontinuities for deflecting a portion of the incident signal onto the detector and for redirecting the output from the light emitter along the through-path. Alternatively, the tap substrate can be provided with a groove for receiving a fiber segment located anywhere along the distribution network.
