10GBASE-T for adapters becomes feasible in late 2011
Because the use of 10GBASE-T PHYs, on dual port server adapters (the predominant version of shipping optical 10GbE adapters) has not been feasible to date and optical interconnects are much more expensive than copper to end users, the market for 10GbE has been stunted.
With the newest versions of 10GBASE-T PHYs, developed using the 40nm semiconductor process, the power constraints of 10GBASE-T are finally being overcome, enabling dual-port 10GbE adapter sales to begin in earnest once adapters using these parts are sold to end users next year.
