High-speed optical time-division-multiplexed/WDM networks and their network elements based on regenerative all-optical ultrafast wavelength converters
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...
متن کاملUltrahigh-speed all-optical data regeneration and wavelength conversion for OTDM systems
The latest results in ultrafast data regeneration and wavelength conversion with SMZ-type all-optical semiconductor switches are reviewed. In these operations, the SMZ-type switch is driven by random data pulses. The fastest bit rate reported to date for such input-data-driven all-optical operation has reached 168 Gb/s. With these all-optical devices, we may be able to build 160-Gb/s OTDM nodes...

Although lightwave technology is meeting the demand for point-to-point and long-haul transport of digital information, routing packets at the nodes of the network has typically been carried out using electronically switched backplane routers. The growing capacity on the Internet is placing an ever greater demand on electronic routing technologies. While WDM can support large aggregate traffic b...
متن کاملBroadcast-and-Select Switching System Based on Optical Time-Division Multiplexing (OTDM) Technology∗
This paper presents large capacity switching systems for a local network using the broadcast-and-select (B&S) architecture. The B&S switching system, based on optical time-division multiplexing (OTDM), can provide several hundreds of Gbit/s by using a nonlinear optical switch as the timechannel selector. Moreover, the combination of OTDM and wavelength-division multiplexing (WDM) can realize th...
