All-optical OTDM add-drop node at 16x10 Gbit/s in between two fibre links of 150 km

We report an error free performance of simultaneous all-optical add-drop multiplexing in a 16×10 Gbit/s OTDM network consisting of a switching node based on gain-transparent operation of a semiconductor optical amplifier between two fibre links of about 150 km each.
