RECEIVER-TRANSMITTER FOR OPTICAL COMMUNICATION DEVICE Russian patent published in 2007 - IPC H04B10/10 H04B10/12 G02B6/10 G02F1/15 

FIELD: optical communications, in particular, laser atmospheric information transfer systems, possible use as single-hop communication line, for example, for setting up communication channel between two clients or between a client and a client access station.

SUBSTANCE: receiver-transmitter for optical communication device is made in form of external and internal blocks which are interconnected by a fiber light duct. The external block is made in all-weather form and contains a focusing system, and internal block is made for room conditions and contains emitters mounted on same substrate closely to each other, represented by laser diodes or light diodes, which constitute a source of optical radiation, and photo-elements, which constitute a receiver of optical radiation. Emitters and photo-elements, positioned on one substrate closely to each other, represent a matrix, engaged with the end of the fiber light duct and commensurate with its end. In the internal block, electronic blocks of emitter and receiver of optical radiation are positioned respectively, and also an interface.

EFFECT: expanded dynamic range of communication line, increased reliability of device operation due to exclusion of fiber combining element, increased reliability, communication quality and information transfer speed due to ensured multi-wave multiplexing, time and frequency packing and encoding of information.
