by optical equipment, carriers are not fully satisfied with the current efficiency. At certain points in transmission, the light wavelengths that travel through the fiber-optic cable must be converted to electronic signals in order to be regenerated, processed, and routed. They are then translated back into the light wavelengths. Although this process takes only microseconds, it does slow the network. An "all-optical" switch could, in theory, eliminate this costly conversion by directing multiple wavelengths t
