160 Gbit/s field transmission over 116 km standard single mode fibre using 160 Gbit/s OTDM and 40 Gbit/s ETDM demultiplexer

T. Systems Nova, Technologiezentrum, the first 160 Gbit/s RZ transmission experiment over field-installed standard fibre G.652 is reported. The transmitter rests upon the optical time division multiplexing (OTDM) technique. At the receiver, a 160 Gbit/s to 40 Gbit/s OTDM demultiplexer followed by 40 Gbit/s electrical signal processing (ETDM) is used. The results are compared with 160 Gbit/s to 10 Gbit/s OTDM demultiplexing experiments. The OTDM demultiplexer is based on cross phase modulation in a semiconductor optical amplifier.
