4/spl times/10 Gbit/s NRZ transmission in the 1310 nm window over 80 km of standard single mode fibre using semiconductor optical amplifiers

Successful WDM transmission of four 10 Gbit/s channels ranging from 1310.5 nm to 1317.4 nm over 80 km was demonstrated. Based on these results and simulations using a time resolved SOA model, we expect to reach 4/spl times/10 Gbit/s transmission over at least 200 km.
