76-km transmission over standard dispersion fiber at 10 Gbit/s using a high-power integrated laser modulator and a PIN receiver without any optical amplifier

We report a high output power (20 mW) integrated laser-modulator device, which allows 10-Gbit/s transmission with a negative alpha parameter over 76 km of standard fiber without any optical amplifier as a result of an average launched power of +3.6 dBm under modulation conditions.
