Abstract
The field of the invention is that of fiber-optic communication devices known as transceivers, used in the aeronautical field for ensuring that on-board electronic computers can converse with one another, or in civil telecommunication. The subject of the invention is a single-channel transceiver comprising essentially a transmitting optoelectronic part, a receiving optoelectronic part, and a specific optical configuration for transmitting and receiving optical signals on a single optical port in real time and using the same wavelength. The optical architectures according to the invention include no semireflecting components, thus making it possible to reduce light energy losses at transmission and reception of the optical signals. These transceivers are particularly well suited for the construction of single-fiber full-duplex optical communication networks allowing simultaneous transmission and reception of signals.
