Abstract:
1. A fiber-optic transceiver adapted for use in transmitting and receiving optical signals in a fiber-optic network, comprising: a multi-mode optical fiber having a longitudinal axis and having a proximal end, said fiber being adapted to convey optical signals in either direction therealong; a photodetector arranged in spaced relation to said fiber proximal end, said photodetector having a sensitive surface operatively arranged to recieve light energy exiting said fiber through said proximal end; and a light source arranged between said fiber proximal end and said photodetector surface, said light source being arranged to shade less than about 25% of the sensitive area of said photodetector surface, said light source being arranged to selectively emit light energy into said fiber through said proximal end.
