The majority of deployed fiber-optic communication links utilize two fibers per link, one for each traffic direction. The transceivers for such links dedicate one fiber for the receiver and one for the transmitter. Single-fiber transceivers, which collapse the bi-directional traffic onto one singlemode fiber using either one or two wavelengths for full-duplex operation, have been in use for a number of years. In particular, single-fiber single-wavelength (SFSW) transceivers have been available but did not exploit some of their inherent advantages.

This article reviews the attributes and benefits of SFSW transceivers, illuminating the advantages for point-to-point communication links. Special attention is paid to critical design elements that enable safe and reliable operation of an optical network with optical return loss (ORL) of 20 dB and better.
