Other folks involved with that demo include Finisar Corp. (Nasdaq: FNSR), Internet2 , and the University of California, Santa Cruz.
(Ironic that the banana slugs had a hand, so to speak, in a 100-Gbit/s Ethernet test.)
For the demo, the 100-Gbit/s signal was split into 10 lines of 10 Gbit/s each, the kind of division that's likely to represent 100-Gbit/s Ethernet's first incarnations. One motivation behind the demo was to show that 100-Gbit/s Ethernet is possible on the current 10-Gbit/s infrastructure, says Drew Perkins, Infinera's chief technology officer.
"We see it as being a big part of the future," says Perkins, adding that Infinera expects Sonet to be "displaced over time with an Ethernet-based transport network."
In terms of technology, the 10x10-Gbit/s configuration is missing one major piece -- "having a chip that sees all 100 Gbit/s," Perkins says. Commercially available media access controller (MAC) chips don't go higher than 40 Gbit/s. Or so it seemed. "Now it turns out the very latest FPGAs are, in fact, capable of [seeing all 100 Gbit/s]," he adds, noting that the group used Xilinx Inc. (Nasdaq: XLNX) chips for the demos.
