Abstract

Bidirectional optical transmission over a single fiber is an important way to increase system's capacity. This paper will present the realization of practical fiber transmission systems based on a new generation of bidirectional optical fiber amplifiers (BID-EDFA), where the bidirectionality of the BID-EDFA is accomplished by using a WDM interference filter. Reliable bidirectional multi-span transmission at 2.5 Gb/s and 10 Gb/s has been achieved with significant system margins. The effect of system performance degradations caused by EDFA gain tilt and multi-path interference are discussed and methods of parameter optimization are outlined. Predicted and measured performances are compared and specific applications are presented.
