Dynamic add/drop of 8-of-16 10 Gb/s channels in 4/spl times/40 km semiconductor-optical-amplifier-based WDM system

We demonstrate the benefits of near-linear SOA-amplified 4/spl times/40 km WDM transmission system. Eight out of sixteen 10 Gb/s channels are added or dropped (with only a 0.7 bB penalty in the remaining channels) over a wide range of time scales.
