Network Transformation for the Metro/Regional Architecture
Digital transformation, cloud networks, and 5G require open and disaggregated network hardware that is controlled and managed with model-driven, open-source upper-layer software systems. The vision for metro/WDM networks is a flexible multivendor architecture that grows incrementally, eliminates vendor lock-in, cuts cost per bit, and easily accommodates new capabilities and features. Traditional chassis-based systems are not built for this type of architecture.
The Shift Towards Open, Disaggregated Networks
As the industry shifts towards open, disaggregated networks, the over-engineered, one-size fits-approach of the past is less and less feasible. Service providers and network operators must evolve their networks to balance the imperatives and budgetary considerations driving modernization against the cost-conscious drive to preserve the often variable useful lifespan of existing assets. Thus, flexibility, the ability to “right-size” networks, and Total Cost of Ownership (TCO), or cost-per-bit, are more and more important.
Supporting Interoperability, Eliminating Vendor Lock-In
Physically disaggregating line systems from transponders and incrementally replacing them with interoperable transponders and Open Line Systems (OLS) is one of the keys to successfully and cost-effectively evolving for openness and disaggregation. One example of the reasons why is the lifespan variation between line systems in comparison to transponders. Disaggregation favors as-needed non-disruptive, in-service replacement of transponders, as well as line systems, which evolve more slowly and have a much longer lifespan. In addition, operators do not want to be restricted in their choice of vendors. Eliminating vendor lock-in gives them the liberty to not only select, but mix-and-match, vendors on the basis of best-of-breed or best value per dollar. These factors are the essence of what right-sizing a network is all about.

Designed for an Open, Multivendor Metro/Regional Network
As right-sizing and disaggregation become more and more important, and traffic demand continues to grow, solutions designed for an open, multivendor environment are becoming a priority. Fujitsu has developed a range of disaggregated, open solutions for ROADM, Add/Drop Complex, Raman Amplifiers and OTDR as separate physical solutions that can be individually upgraded. As a result, metro and regional operators can not only right-size their network today, they can continue to right-size it going forward.
