Abstract

A device for monitoring light traveling in an optical fiber having a body, a passage in the body adapted to receive an optical fiber, a discontinuity in a portion of an optical fiber received in the passage through which light can exit the fiber, and an optical detector unit adapted to provide a signal representative of light exiting the received fiber through the discontinuity. The device can include provision for monitoring a selectable one of a plurality of fibers, and may be constructed either as a standalone unit for attachment to a multiple fiber signal connector device such as an optical crossbar switch, or as an integral part of a switch or other optical device. The discontinuity may be formed as a permanent part of a fiber through which the signal to be monitored passes, or may be formed temporarily when a signal in a fiber is to be monitored.
