Providing that wavelength division multiplexing (WDM) technology reaches a significant level of maturity in the near future (i.e., achieves cost marks suitable for massmarket FTTH applications), the number of individual wavelength channels in a single EPON could be increased, adding a separate WDM overlay on top of existing burst mode operated systems. In this scheme, some of the already deployed and active ONUs would be assigned, in a static manner, to a distinct wavelength domain for both upstream and downstream transmission lanes. While the effective data rate on each wavelength would remain the same, there would simply be fewer ONUs to share that raw bandwidth capacity, increasing the bandwidth available per subscriber. The extreme example of this approach would be a WDM PON system wherein each subscriber is allocated unique wavelengths for upstream and downstream transmission. It is still not clear when WDM components will be available at the appropriate prices to make this solution commercially viable. The price of the tuneable laser sources applicable for the ONUs is continuously dropping, allowing for development of colourless subscriber units, though the necessary control electronics, wavelength tracking systems and the need to employ the DWDM channel allocation to assure sufficient number of subscribers are still cost-prohibitive. The complexity of the OLT unit connected with the need for a dedicated receiver per subscriber port as well as highly complicated wavelength allocation plan and the requirement for a special wavelength allocation protocol make the management of WDM PON a real nightmare from the logistic point of view. DWDM systems, which would be needed for the -per customer systems just described, operate over a narrow band of frequencies known as the C- and L-bands (between 1530 and 1620 nm). The wavelengths must be tightly bunched together, fitting from 32 to 128 channels in the C- and L-bands. Coarse WDM (CWDM), in contrast, operates on a much wider range of wavelengths (1270 1610 nm), with a maximum of 18 channels separated by 20 nm intervals. Figure 7.6 shows a mapping of the

2. If multiple paths to the root are available with the same accumulated path cost, the switch will choose the neighboring switch (that the switch would go through to reach the root) with the lowest switch ID value. 3. If multiple paths all go through the same neighboring switch, it will choose the local port with the lowest priority value. 4. If the priority values are the same between the ports, it will choose the physically lowest numbered port on the switch. For example, on a 2960, that would be FastEthernet 0/1 or Gigabit 0/1. After going through this selection process, the switch will have one, and only one, port that will become its root port.
