Paper Abstract

While most OADM systems deployed today are static, carriers offering new wavelength services, are looking for ways to migrate towards reconfigurable OADM and dynamically reconfigurable OADM. ROADMs allow carriers to automate service provisioning, wavelength management and failsafe mechanisms, thereby eliminating slow, costly and error-prone manual network configuration. And although next-generation systems offer this flexibility as an integral part of their architecture, carriers must protect their existing investment, extending the life of their existing networks. This article examines the use of add-on optical switching systems, as a cost- and time-effective means for upgrading legacy networks. Two examples are given. In the first, a static OADM is upgraded into a reconfigurable system. The second example shows how existing OADM systems can be upgraded to support dynamic reconfigurability. The article examines also particular advantages of Planar Lightwave Circuits (PLC) for these applications.
