RECEIVING-TRANSMITTING DEVICE FOR OPTICAL ATMOSPHERIC COMMUNICATION LINE Russian patent published in 2007 - IPC H04B10/10 

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

SUBSTANCE: the device is made in form of external and internal blocks which are interconnected by cable, inside of which light guides are positioned. External block is made in all-weather form, positioned in a sealed body and contains focusing system, while internal block is made for room conditions, located inside a body and contains mounted interface, optical radiation emitter and optical radiation receivers. Ends of light guides, positioned in external block, are combined in one dense cluster, forming a fiber-optic collector, while other ends of light guides, placed within a cable, are positioned inside an internal block and optically connected to one optical radiation emitter and to optical radiation receivers with possible commutation by means of commutator positioned in the internal block.

EFFECT: ensured operative readjustment of optical scheme of device, increased reliability of its operation due to expansion of angular aperture for receipt and transmission of optical signal and excluded manual adjustment of optical part of device; increased energy resource of communication line due to prevented optical losses during receipt and transmission of signals.
