They had another bit wrong too. Today's long haul transport lasers go up to 40Gig. Not too cheap either. A 40G transponder from Ciena will run you $75,000
What they are doing here is called WDM (wave division multiplexing). There has been a standard for a while on WDM. But the thing is this only allows you to cram more information down one pipe it doesn't shrink the equipment on either end. They need to stick in and OC-48 for each wave length, so you would need about 1 foot ball field of space to stick all of the equiptment for this one piece of fiber. To sum it up don't expect to see any dramatic speedups anytime soon
First of all let me clarify that when I say MHz I am referring to the data cycles and not the clock cycles. Its much easier to talk this way when dealing with products that transfer data on both the rising and falling edge. First of all to get Rambus with 2x the bandwidth of 200 MHz DDR ram it would have to be going at 1.6GHz. Why such a high number? Well very simple Rambus Ram has a quarter the bus width of DDR ram. 16 vs. 64 bit. so your 800MHz Rambus ram only equals the 200Mhz DDR ram. I should also put in that there is also 266MHz DDR ram. Letting DDR not only equal but exceed the bandwidth of rambus ram at a dramatically lower cost.

Duuuuude... thats just wrong.
Canada is our last dumping groun to the north... I mean come on what else could they be good for?
