This is Fiber Tap? Light Reading.com had an interesting article recently on the potential impact of coherent optical technology on submarine cable capacity, which in many cases was built for the old “10 Gbps Information Super Highway”. Today, the Internet is much more than that, with mobile, video, and cloud services dominating growth. The key point is that new technology is enabling existing systems to be easily upgraded from 10 Gbps to 40 Gbps and 100 Gbps simply by replacing the DWDM equipment, without the cost to deploy new cable and other costly fiber infrastructure. As a result, companies which specialize in undersea cable deployments face economic challenges because of the lack of needed new projects. Why buy new when you can supercharge existing assets, especially in this economy?
We’ve seen this trend to upgrade ourselves, both for submarine systems and terrestrial cable by operators looking to deploy the Next Generation Internet – the one that is going to carry millions of video minutes every second. Iceland’s FARICE for example, tested our coherent optical technology at 100 Gbps on one of their undersea links, and we’ve also recently completed successful 100 Gbps terrestrial trials with BT along with one of Russia’s largest mobile carriers, MegaFon.
Cisco’s VNI is clear evidence that speeds must evolve to 100G and beyond. However, the next strategic investments should consider more than simple performance improvements. Service providers should not miss out on a chance to optimize their architecture when they make the leap from 10 Gbps to 100 Gbps and beyond. They should also consider how new, more flexible and elastic architectures can improve network operations and lower costs by making more efficient use of available bandwidth. That’s one of the key benefits of Cisco’s nLight™ technology, which shares information between the optical and packet layers, helping to automate end-to-end service provisioning and provide dynamic management of the optical and routing layers. This ensures that capacity is only provisioned as needed and optimizes the utilization of network resources. ACG Research performed an analysis and determined that nLight can reduce costs by up to 50% for protected traffic.
