As demand for bandwidth capacity and pressures on per-bit revenue grow, operators need to transform their infrastructures into high-performance yet cost-efficient systems. The most effective operators recognize that the days of optimizing different network layers piecemeal have passed. Today, they must evaluate and optimize networks as a whole, from the fiber and optical transport layers to packet and TDM switches. JDSU understands the value of networks with simplified and less-expensive upper layers through the added functionality of more robust, resilient, and reliable lower layers. And, we understand the bottom line: faster end-to-end service delivery that dramatically increases customer capture and reduces network churn.
As the world’s expert in ROADMs, JDSU led the industry in advancing agile optical networks, and now JDSU continues its tradition of collaborative innovation by enabling self-aware networks.
A network with an agile photonic layer—colorless, directionless, and contentionless nodes, mesh architecture, and the like—flexibly adapts to changing traffic patterns, new consumer applications, and evolving changes to the network itself. This agility enables faster photonic restoration, easier load balancing, proactive maintenance switching, and transponder pre-deployment. Such an operationally efficient system, one that requires less complex planning and minimal manual intervention, ensures optimal performance for the least cost: reducing both CapEx and OpEx.
As the industry builds out 40 G and 100 G deployments, fiber characterization, amplification, and dispersion compensation are critical components. Characterization of the physical layer is a prerequisite to any fundamental network upgrade. Designers will then implement Raman and other advanced amplification technologies to maintain reach at significantly higher speeds and capacities. Lastly, the growing use of coherent reception technology will compensate for massive amounts of chromatic and polarization mode dispersion.
Reducing costly, redundant hardware, maximizing fiber capacity, and lowering OpEx are just some of the benefits of the self-aware network. Enabling a self-healing photonic layer means fewer packet and TDM switches. A control plane with full visibility and control of the photonic network enables constant, automatic balancing of traffic loads. The ability to re-route immediately—and automatically—removes the need for costly, urgent fault repairs. And, functional integration lowers overall power requirements to more easily meet green environmental mandates.
From design through deployment, modular, cost-efficient communications test and measurement tools are critical components in the lab, the production floor, and the field—encompassing protocol layers such as the optical transport network (OTN) and MPLS/Ethernet. Fiber, DWDM, and ROADM infrastructure requires characterization, and emerging applications require testing at 40 GE/OTU3 and 100 GE/OTU4. Another vital component is tested and trusted expertise that can properly evaluate data and make quality judgment calls on proposed and existing network configurations.
