FIBER-OPTICAL SYSTEM FOR SAFE INFORMATION TRANSMISSION Russian patent published in 1997 - IPC

Abstract RU 2100906 C1

FIELD: radio engineering, in particular, transmission of optical signals. SUBSTANCE: transmitting part of device has code noise unit 1, switch 2, alarm warning generator 3, pulse-position modulator 4, control unit 5, light source 6, T-shaped splitter 7, photo diode 8, stabilization unit 9. Receiving part of device has photo-diode 11, amplifier 12, relay generator 13, self-test unit 14, pulse-position demodulator 15, analyzer 16, code noise decoder 17. EFFECT: increased length of optical communication line, decreased sensitivity of self-test unit while keeping protection safety of information to be transmitted. 7 cl, 25 dwg
