10 Gbit/s RZ transmission at 1309 nm over 420 km using a chain of multiple quantum well semiconductor optical amplifier modules at 38 km intervals

Abstract

Using an 1309 nm RZ transmitter at 10 Gbit/s and a chain of semiconductor optical amplifiers a record high transmission capacity of 4200 Gbit-km/s has been established. RZ 10 Gbit/s transmission at 1309 nm over a 420 km standard single mode fibre link with lumped amplification is demonstrated. A total of 12 multiple quantum well optical amplifiers were used to compensate for the fibre losses.
