All CoreDirector optical interfaces may be software-configured for full wavelength switching or channelized STS-n granularity ...

... of OTU-1, as shown in Figure 3. Notice these rates are equal to or slightly above the total bit rates of a SONET/SDH OC-48/STM-16, OC-192/STM-64 and OC-768/STM-256 respectively, allowing those signals to be transported transparently. OTU-2 also can carry a full 10GbE LAN PHY, unlike SONET/SDH OC-192 ...

Introduction Significant changes in the communication landscape have altered the way networks are built. Traditional low-speed Time Division Multiplexing (TDM) services are being replaced rapidly by a variety of new-generation optical services, many of which are optimized for packet traffic. A new paradigm ...
