INTERFACE FOR TRANSFERRING DISCRETE INFORMATION THROUGH OPTICAL CHANNEL Russian patent published in 2006 - IPC H04B10/00 

FIELD: systems for transferring discrete asynchronous information through fiber-optics or open optical channel; channel level of transfer system (sublevel of medium access control).

SUBSTANCE: transferred bits of information are converted into optical signals using the number of transferred bits of information. These signals are multiplexed in optical range by delays for defined time intervals and by changing wave-length, and grouped optical signal is forwarded to the transfer channel. On the receiving end of transfer channel the optical signal is demultiplexed, signal parts are delayed for defined time intervals and detect. Transferred bytes of information are put to output buffer register using synchronizing signal, which is transferred simultaneously with informational bits. Unlike known interfaces, the proposed interface does not have numerous coding and decoding, grouping of transferred messages into frames, etc. Due to these facts, useful information transfer speed is increased; noise immunity is improved, especially in impulse noise environment and outer mechanical and climate factors.

EFFECT: increased noise immunity in impulse noise environment.
