High Capacity Optical Transmission
Overcome the limitations imposed by the fibre’s attenuation, dispersion and non-linearities.
We are pushing the limits towards multiple Perabit/s capacities. Key topics are Space-division multiplexing techniques employing novel multi-mode/core fibers, advanced signal modulation for improved spectral efficiency, dense wavelength multiplexing, compensation of (non-linear) fibre dispersion effects, robust coherent reception using digital signal processing, and single and multi-mode wideband optical amplification schemes.
