Abstract
Methods and apparatus for varying the transmission rate of a signal transmitted within a dense wavelength division multiplexing (DWDM) system or network are disclosed. According to one aspect of the present invention, a method includes obtaining a first signal and determining a transmission rate associated with the first. If it is determined that the transmission rate is a first rate, the method includes processing the first signal as having a first transmission format and the first rate. Alternatively, it is determined that the transmission rate is not the first rate and is a second rate, the method includes processing the first signal as having a second transmission format and a second rate.
