Paper Abstract

The work presents simulation of transmission line results with the fiber standard ITU-T G.652. The parameters of Lorenz laser decide about electrical signal parameters like eye pattern, jitter, BER, S/N, Q-factor, scattering diagram. For a short line lasers with linewidth larger than 100MHz can be used. In the paper cases for 10 Gbit/s and 40 Gbit/s transmission and the fiber length 30km, 50km, and 70km are calculated. The average open eye patterns were 1*10-5-120*10-5. The Q factor was 10-23dB. In calcuations the bit error rate (BER) was 10-40-10-4. If the bandwidth of Lorenz laser increases from 10 MHz to 500MHz a distance of transmission decrease from 70km to 30km. Very important for transmission distance is a rate bit of transmitter. If a bit rate increase from 10Gbit/s to 40 Gbit/s, the transmission distance for the signal mode fiber G.652 will decrease from 70km to 5km.
