RT Journal Article ID 4142a7b2449d5a48 A1 Omarov, M. A. A1 Tsekhmistro, R. I. T1 Dispersional Restriction of the Transmission Link Length in Quantum Cryptographic Telecommunication Systems with Polarization Encoding JF Telecommunications and Radio Engineering JO TRE YR 2009 FD 2009-12-16 VO 68 IS 20 SP 1841 OP 1848 AB The existing means for increasing of transmission stability in quantum and fiber optic telecommunication systems with polarization encoding are analyzed. It is suggested the evaluation of signal propagation delay incurred by dispersion inherent to the present-day fiber optic applied in the systems of transmission up to 150...2000 km as compared to the coherence interval of GaAs semiconductor lasers. Recommendations on optimal application of optical fiber and laser in practically used quantum cryptographic transmission systems with polarization encoding are provided.
