1.6 Tb/s (40x40 Gb/s) Total Capacity 4-Node Optical Networking by Using Fully Programmable A/D Devices

A 4-node dynamically reconfigurable optical network, using integrated add/drop devices, is demonstrated. Aggregate capacity of 1.6 Tb/s (40x40 Gbs), spectral efficiency of 0.4 bits/s/Hz, Q values larger than 18 dB and wide tolerance to wavelength misalignment are key results.
