Abstract
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.
