Abstract :
Progress in trunk transmission technologies and the impact that these systems may have on the next generation high-speed communication networks are discussed. A nonrepeatered, long-span system field test carried out at 600 Mb/s is reported. The prototype system, using multiple in-line erbium-doped fiber amplifiers and installed dispersion shifted single-mode fiber cables, was tested over a span of 300 km. Repeater spacing compatibility with the existing 600 Mb/s system was confirmed, and capacity upgradability to 10 Gb/s was verified. The bit-rate flexibility of the optical fiber amplifiers is discussed.<>
