Testbed for 100 Gb/s Ethernet

A testbed implementation for 100 Gb/s Ethernet optical time division multiplexing experiments is described along with optical subsystems used in its implementation. Testbed potentialities relating to wavelength division multiplexing and hybrid wavelength/polarization division multiplexing implementations are also described. First experimental results at 20 Gb/s are carried out demonstrating a power penalty lower than 1 dB.
