Abstract
10 Gbit/s long distance transmission at 1.55 μm on standard single mode fibers (SSMF) has attracted a widespread interest because of the increasing need to upgrade existing transmission systems. Recently, unrepeatered transmission over 182 km [1] and 204 km [2], respectively, and unregenerated transmission over 253 km in a DST system with optical in-line amplifiers [3] have been reported. Here, we demonstrate experimentally for the first time unregenerated single channel 10 Gbit/s transmission at 1.55 μm over 300.4 km SSMF with two in-line amplifiers by employing pre-chirped ASK modulation.
