摘要：

An experiment which uses integrated optics to effect bidirectional transmission on a single-mode fiber is described. The system has practical applications and provides more functionality than previously reported experimental systems. It consists of a video link (180 Mb/s) and a voice/data link (1.54 Mb/s) to the end user and a return voice/data link (1.54 Mb/s) from the end user. Two LiNbO3 devices are used to modulate the laser externally and a third is used in a novel way to demultiplex the incoming signals and to eliminate the need for an optical source at the user's end. The system operated over 4 km of standard single-mode fiber with a BER &le 10-9 and excess margins (4.9, 9.3 and 28.1 dB) on the three links.
