Straight line 10 Gbit/s soliton transmission over 1000 km of standard fibre with in-line chirped fibre grating for partial dispersion compensation

摘要

The authors demonstrate a highly practical and robust soliton transmission system with partial dispersion compensation. Error free transmission was obtained for 10 Gbit/s data over 1000 km of standard fibre with nominal dispersion of 17 psm.km. Despite variations in the dispersion compensation ratio and the relatively high UV-induced birefringence of the fibre gratings, the system exhibits BERs>10/sup -10/ for any state of input polarisation provided that the average intra-span dispersion is negative.
