Advances in multi-channel optical multi-gbytes/sec bit-parallel WDMsingle fiber link

摘要

For ultra-high-speed single media parallel interconnects, an alloptical single fiber WDM format of transmitting parallel bits ratherthan a fiber ribbon format where parallel bits are sent throughcorresponding parallel fibers in a ribbon format, can be the media ofchoice. Here, we shall discuss the realization of a multi-km xgbytes/sec bit-parallel WDM (BP-WDM) single fiber link. Thedistance-speed product of this single fiber link is more than severalorders of magnitude higher than that of a fiber ribbon link. The designof a 12 bit-parallel channels WDM system operating at 1 Gbit/sec perchannel rate through a single fiber will first be presented.Experimental results for a two channel system operating at that rate aregiven. Further improvement of distance-speed product for the BP-WDM linkcan be obtained with JPL's newly developed 20 Gbits/sec per channellaser diode array transmitter. Also, new computer simulation results onhow a large amplitude co-propagating pulse may induce pulse compressionon all the co-propagating data pulses, thereby improving the shaping ofthese pulses for a WDM system, will be presented and discussed. Theexistence of WDM solitons is also shown
