A unidirectional multiple-quantum-well booster amplifier module for th
e 1310-Mm transmission window with a high 3-dB gain saturation output
power of 18 dBm and a fiber-to-fiber gain of 17 db is demonstrated, Th
e module is equiped with a polarization-maintaining input fiber and op
tical isolators have been included, The booster amplifier was tested w
ith a 1310-nm DFB laser directly modulated at 10 Gb/s, showing that 14
.6 dBm of average fiber-launched output power could be obtained at 1 d
B BER penalty, and that power budgets of 26.8 dB and 39.4 dB could be
realized for a PIN photodiode receiver and an optically preamplified r
eceiver, respectively, making repeaterless 10 Gb/s transmission over 7
0 to 100 km of standard single-mode optical fiber at 1310 mn a practic
al option.
