Abstract
An optical transceiver assembly for use in a bidirectional system includes an optical fiber to which an outgoing optical signal is coupled. To reduce reflections from the end face of the fiber, the end face is beveled at an acute angle .phi.' to the normal to the fiber axis, and the fiber axis is tilted at an acute angle .theta. to the transmission axis. Preferably, .phi.'.apprxeq.2.theta.. In this manner, crosstalk is reduced without significantly sacrificing coupling efficiency.
