Here is another article on 10-Gbs which gives a few more specifics on the 'blade' used by Extreme. It wouldn't surprise me if Luminent supplied several of these guys w/product. The Zuma box could be a monster, & w/MRV at its current price levels, you get it for what, a couple of bucks? Crazy.
"Early In The Market
The prominent new service providers do a fair amount of
stumping for their equipment suppliers as part of their sales pitches. For example, Yipes touts Extreme Networks, Cogent uses Cisco and Telseon features Riverstone gear. All three vendors have nonstandard 8- or 10-Gbps interfaces based on wavelength division multiplexing (WDM), ..."
"Extreme Networks also has an 8-Gbps WDM blade for its
Layer 3 switch family. According to Extreme worldwide
marketing VP, George Prodan, "The clocking rate on the fiber
is 10 Gbps. Into that we are able to mux eight channels of
full-duplex 100-Mbps Ethernet—that's eight lambdas onto a
single 10-Gbps pair—and run it up to 35 kilometers."
Prodan said the Extreme 8-Gbps blade also supports
802.3ad link aggregation—the standard for bonding multiple
Ethernet channels to make a larger-capacity link—and can
run bidirectionally. Extreme designs its own switch fabric and MAC silicon, Prodan said. "If you seriously want to
differentiate yourself, then the core of your switches and
most of your silicon should be custom, so you can write your
own specialized software—the routing and QOS code," he
said. "We can give our customers a lot of knobs they can
twist in terms of QOS, bandwidth allocation, rate shaping and traffic engineering."
