What is Fiber Delay Lines

Optical networking technologies can play a significant role in the realization of grid and data centre systems. The new and developing internet applications are progressively becoming high performance and network based, and the performance of these applications are depending on the optical network and cloud computing services. In this chapter, the authors discuss the capabilities of optical transmission and the switching techniques. An AWG-based optical switch is discussed in the chapter and the performance of switch is measured in physical and network layer parameters. Design modifications in the switch is suggested, for improving the performance of switch. The overall performance of switch is also measured when the switch is placed into the network where cascading of two or more switches are required.
