Abstract: An apparatus that includes one or more electrical or optical I/O ports that interface to external communication equipment, one or more optical ports that interface to an optical transport network that carries wavelength-division-multiplexed (WDM) optical signals, one or more tunable optical transceivers, and packet switching logic. The apparatus is configured to perform packet processing operations for ingress and egress data frames or packets. The apparatus can further include control circuitry that can take part in an automatic provisioning process that configures the tunable optical transceiver units of the network device, specifically configuring the optical channels/wavelengths of the optical signals that are transmitted by the tunable optical transceivers.
