A primer on ROADM architectures
Klaus Grobe (ADVA Optical Networking)
As bandwidth consumption continues to explode in a challenging economic environment, Research & Education institutions need to optimize their network’s efficiency and deliver more with less. Effective use of Reconfigurable Optical Add Drop Multiplexers (ROADMs) is key to this strategy. Increasing the flexibility, scalability, and remote configurability of a network lowers Operational Expenses (OPEX). Using ROADMs, a network operator can quickly turn up new services and connections, alter networks as needed and eliminate manual intervention through remote management. However, the ROADM landscape is large and diverse, and all the available technologies and architectures can at times be confusing and potentially prevent an operator from maximizing the network’s potential. This poster explores ROADM technologies and architectures and the various ways they are used in networks to increase efficiency. Specific attention is given to the latest advances of colorless and directionless implementations and GMPLS control plane support.
