Abstract

A repeaterless transmission experiment through 160 km of non-dispersion-shifted fiber at bit rate of 2.5 Gb/s is reported. A direct-current-modulated distributed-feedback laser in conjunction with an erbium-doped fiber amplifier for power amplification constitute the transmitter. The regenerator includes the conventional APD photodetector and the subsequent amplifiers and timing recovery circuit. With careful decision level and laser bias adjustment, less than 0.6 dB of overall system degradation is incurred in this simple system configuration.<>
