Abstract
Optical communications system using traveling wave semiconductor optical amplifiers has at lest one optical fiber (2), tranceivers, (S1. . . , SN) placed along the fiber and having in each case at least one travelling wave semiconductor optical amplifier (A1. . . , AN), which is located in series with the fiber and transmission means (L1, L2) for feeding into the fiber at least one continuous optical signal. Each amplifier is used alternately to modulate the continuous optical signal in order to transmit information, and to detect information modulations of the optical signal which carry information.
