Economic readiness
Customers would like
40G transponders at 2.5X 10G transponder cost
100G transponders at similar proportional savings

Business case will initially be made based on:
Economic benefit at the overall network solution level
Including CAPEX and OPEX for IP, DWDM and fiber

A reasonable 100G initial economic target: 100G = 2.5 X cost of 40G
Parity in cost/bit, with improved spectral efficiency
Definition of ÒacceptableÓ cost ratio with respect to 10G will vary with customer
