10-Gbit/s error-free transmission of 2-ps pulses over a 45-km span using distributed Raman amplification at 1300 nm

Summary form only given. To meet the requirements of upgrading existing optical fiber networks and to considerably extend the potentially useable bandwidth in the low-loss region in optical fibers, broadband, fiber-based amplifiers outside the Er gain window are required. The wavelength flexibility of Raman fiber amplifiers make them very attractive for integration in current and future systems. Here we report the results of 10-Gbit/s, 2-ps transmission at 1300 nm using distributed Raman amplification. Almost no penalty has been observed for the experimental situation where the system loss was directly compensated by the Raman gain and where an excess gain of +8 dB was achieved.
