HIGH-OUTPUT-POWER (-NM MULTIPLE-QUANTUM-WELL BOOSTER AMPLIFIER MODULE(15 DBM) UNIDIRECTIONAL 1310)

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.
