Evolve Your Legacy DWDM Network With CDC-ROADM
CDC-ROADM technologies help operators to break out of the traditional confines of fixed grid architectures. This empowers operators to allow for greater agility and survivability of wavelength services within the ROADM construct.
It is important to understand that CDC-ROADMs offer many upgrades as compared to traditional fixed grid solutions, however some operators may decide that a fixed grid solution still provides some benefit to their system. It is entirely possible to run a fixed grid solution within the same ROADM environment as a CDC-ROADM. In this situation the operator has the ability to provision services as either fixed grid wavelengths or leverage their CDC portion of the spectrum to take advantage of the colorless, directionless and contentionless capabilities.
Traditional fixed grid solutions suffer several shortcomings. Those essentially break down to a lack of colorless, directionless and contentionless capabilities. Moreover, a CDC-ROADM can automatically restore failed services along another path from source to destination.
Ultimately, the ideal next generation optical transport solution lies within leveraging Flex Spectrum technology in tandem with CDC-ROADM capabilities. With this type of solution, an operator has the ease in knowing their transport system will support higher bandwidth applications of today and far into the future. Additionally, the operator empowers the network to restore services automatically in the event of a failure with the colorless, directionless and contentionless capabilities.
