[c-nsp] Does 6500 10 GigE currently support WAN-PHY?

[Tantsura, Jeff]

The bottom line - it's all about the money (as usual) 

The price difference between LAN/WAN cards on some older DWDM equipment 
(Lucent) could be factor 5.

WAN PHY is OC192 framed, can thus be carried over legacy OC192 DWDM 
infrastructure (DWDM only, not SONET due to clocking being less than 
SONET grade accuracy).

So if your DWDM system doesn't have 10GE LAN PHY capability (10.3 GHz 
64b/66b coding) then WAN PHY with its OC192 compatible coding (9.5GHz) is 
very interesting.
