Abstract
A billing system comprises an optical system that uses a variable magnification mirror to split-off a sample of the DWDM-carrier through traffic. A pair of wedge-filters are alternatively included to add/drop particular carriers according to their respective wavelengths. The selected carrier sample is then processed through a CISCO 12000 gigabit switch router such that billing information is output that is useful to an optical Internet backbone carrier.
