WDM interconnection using PLC hybrid technology for 5 Tbit/s electrical switching system

We have developed a 500 GHz channel spacing 8-wavelength 2.5 Gbit/s optical interconnection system for a 5 Tbit/s electrical switching system. We fabricated compact WDM transmitter and receiver modules using PLC (planar lightwave circuit) hybrid technologies. An optical interconnection employing the optical modules together with a cyclic-frequency AWG (arrayed waveguide grating) router operated successfully.
