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. %8 2009-12-16
