Abstract

The use of low-loss optical fibers as a medium for guided-wave communication systems has recently become feasible. The dominant source of loss in such a medium may well be scattering. When this is the case, a substantial amount of signal power may reach the receiver as the result of two back scatterings, i.e., double-reverse scattering. It is concluded that under practical conditions a surprisingly large amount of power can reach the receiver via this mechanism but that despite this fact the effect on system performance is nearly negligible in most cases. Since this is an intrachannel interference problem and not a noise problem, the effect can be reduced if necessary by means of a simple equalizer, which is described.
