Abstract
Apparatus for bidirectional transmission of optical signals between two stations connected by a light transmission path of optical fibers, each station including a laser module comprised of a laser diode and an adjacent monitor diode, the latter performing the dual functions of detecting light emitted by such laser diode in its transmission mode, and for detecting light transmitted from the other station when such adjacent laser diode is not in its transmission mode.
