1.6 Tbit/s (40×40 Gbit/s) total capacity four-node optical networking using fully programmable A/D devices

A four-node dynamically reconfigurable optical network, using integrated add/drop devices, is demonstrated. Aggregate capacity of 1.6 Tbit/s (40x40 Gbit/s), spectral efficiency of 0.4 bit/s/Hz, Q values >18 dB and wide tolerance to wavelength misalignment are key results
