> That certainly is not due to costs, hardware for bigger pipes never gets more expensive the more you buy. That depends. It's currently the case for 100gig (minus xconnect costs) depending on vendor platform. Cisco's yield on their CPAK modules is rumored to be in the low single digits. If you can actually get your hands on a working module, they're crazy expensive right now. People are hoarding them and saying "which customer is this really worth or will pay me the most?" The Cisco 100gig situation is so bad right now, that there is a very large international carrier looking to replace their Cisco edge with Juniper.
