Summary :

Basic characteristics of Erbium-doped fiber laser amplifier (EDFA) pumped by laser diodes with oscillating wavelength of 1.48µm are measured. Unsaturated gain of 26 dB, 3 dB saturation output power of 1 mW, and noise figure of 5.5 dB are obtained. As a result of transmission experiment using the EDFA at 1.8 Gbit/s over 210 km, linear repeater gain of 20 dB is achieved by considering loss of optical band pass filter and power penalty due to degradation of extinction ratio. By using the basic parameters obtained experimentally, maximum regenerative repeater spacing are calculated in a direct detection transmission system with EDFA repeaters. It is clarified that theoretical regenerative repeater spacing of 5000 km can be achieved by using 50 amplifiers with gain of 20 dB and noise figure of 6 dB, including coupling loss of 0.5 dB, at a bit rate of 2 Gbit/s.
