Unformatted text preview: References 651 transmitted out of each port on the wavelength router. Assume that in addition to the standard loss, we get only 1 / 2 N of the transmitted power in each channel, where N is the number of ONUs. 11.2 Consider the RITENET architecture shown in Figure 11.10. Suppose the laser speed at the CO is limited to 155 Mb/s. The network needs to support 20 ONUs and provide each ONU with 10 Mb/s bandwidth from the CO to the ONU and 2 Mb/s from the ONU to the CO. How could you modify the architecture to support this requirement? References [Aar95] R. Aaron, editor.
