چکیده
We describe an optical time-division-multiplexed (OTDM)/WDM network architecture that integrates high-speed optical time-division multiplexing at speeds of 40 Gbit/s and higher with lower-bit-rate WDM channels. An ultrafast wavelength converter is used as a regenerative multifunction building block for OTDM multiplexing, WDM-to-OTDM and OTDM-to-WDM transmultiplexing, OTDM/WDM multicasting, OTDM all-optical label read–write, and all-optical time-channel add–drop multiplexing. Subsystem design and underlying component technologies are described in detail. New results and performance measurements are shown at 40 and at 80 Gbit/s. © 2004 Optical Society of America
