Cisco 100G DWDM– Works Anywhere Over Anything

GregSmith Bio Photo3By Greg Smith, Service Provider Marketing Manager, Cisco

OK, so the title of this article isn’t totally accurate. Cisco’s 100G DWDM solution won’t work over barbed wire, or Cat-5 cable, or cotton string, but it will work on over 95% of the existing fiber in the ground, including systems that were designed to operate at 10 Gbps. Why is this important? Because 100G services aren’t just for large cities and international carriers. Even rural locations are starting to see Internet growth rates fast enough to justify the leap to 100G.

For example, to prepare for anticipated growth of IP network traffic, two independent communications providers in Wyoming recently completed a successful trial of a 100 Gbps optical connection. Silver Star Communications, based in Thayne WY, and Advanced Communications Technology (ACT), from Sheridan WY, completed this trial across 420 miles of existing fiber, over multiple networks in conjunction with Cisco in early April 2013.

Breaking the Network Bottleneck: Why is 100G So Important?

UntitledService providers are rapidly transitioning their networks to 100 Gbps  in the core and it seems that every week brings a new technology, product, or customer announcement.  With that in mind we encourage you to join us at an upcoming webinar, 100G Optics: Why Operators Are Upgrading Now. It will feature results from surveys by Infonetics Research with top service providers, and explains what is driving upgrades to 100G and how carriers plan to make the transition. We’ll cover not just the core but future metro opportunities as well. Read More »

Cisco Continues Enhancing Core Routing Capabilities

When Cisco announced the CRS (Carrier Routing System) in 2004, many analysts and other observers thought it overkill.   Some said that Cisco would not sell more than 50.

To date, the number is greater than 8000.

That would seem to fall into the category of “Exceeding Expectations”.

And just how did Cisco do this?  In part, by continually staying ahead of the game with enhancements – never waiting for traffic loads, customer demands or other circumstances to force it into catch-up mode.

Today, Cisco continued that practice with further enhancements to the industry-leading CRS platform.

Cisco announced that GTS Central Europe (GTS CE), a leading provider of integrated telecommunications solutions and data center services in Central and Eastern Europe, has deployed the CRS for its Next-Generation Internet core.  Cisco new elastic core networking capabilities enable service providers such as GTS CE to cost-effectively launch and scale revenue-generating services within minutes instead of months.  The solution includes the industry’s first integrated coherent 100 Gbps IP over DWDM and Cisco’s nLight™ technology for the CRS.

Cisco’s nLight technology converges IP and optical transport networks by introducing programmability to minimize network complexity while maximizing service intelligence and monetization opportunities.  This capability significantly reduces network total cost of ownership and is a key element of the Cisco Open Network Environment (ONE) framework. 

Also, in recent related news, Cisco and BT recently conducted a landmark 100G DWDM trial

Greece Ready for 100G Internet

One of the most interesting aspects of the Cisco Visual Networking Index is how the explosion of Internet traffic is taking place everywhere. We’ve talked before about how countries such as Iceland and Bermuda are leveraging high speed connections to the world to grow their economies. This time let’s look at Greece and competitive carrier hellas online (hol) on how they are preparing for the zettabyte era. (A zettabyte is 1021 bytes, in case you had forgotten).

Hol is one of the largest fixed-line telecommunications services providers in Greece offering a range of retail, business and wholesale services, and they also own the most extensive core backbone network in Greece. Their fiber optical network stretches over 4166 km nationwide and recently they’ve started offering an on-demand interactive video service called “hol video club” that has really taken off. Despite the challenges of the European economic situation, hol is continuing to see not just increases in bandwidth demand but also gains in the number of subscribers. Most recently they’ve seen increasing growth in cloud-based services as well.

Hol is also one of the most recent carriers to put Cisco’s 100G coherent optical solution through its paces. For hol, 100G offers a solution to meet their need for as-needed, cost-effective bandwidth growth without the need to replace any fiber infrastructure. This is a common situation – carriers are finding the 10G links are no longer sufficient; yet running multiple 10Gs in parallel is not optimal. The challenge has been finding a solution which simply enables “plug in play” upgrades to 100G. This was one of the key objectives of the Cisco engineering team who developed the 100G DWDM solution. To make 100G widely deployable and commercially successful, it needed to have similar performance and engineering specifications as previously deployed 10G links.

Hol’s successful trial of the dense wavelength division multiplexing solution was run between two Read More »

The Chappe Network: Enabling the Kilobyte Era in France

By Greg Smith, Service Provider Marketing Manager, Cisco

Today we take instant communications for granted and our latest Cisco Visual Networking Index predicts that we’ll soon reach the “Zettabyte Era” for global IP traffic (a zettabyte being 10^21 bytes). Recently I had an opportunity to see a bit of telecommunications history from what I’ll call the “Kilobyte Era”. While visiting a family I knew in Saverne, a small town outside of Strasbourg, France we toured a local castle (Castle Haut-Barr) with a view of the countryside. Besides the 12th century castle there was a (restored) tower from the original Paris-Strasbourg optical semaphore system, one of the first communications networks in the world. I’d read about this system but never actually seen it and my hosts were gracious enough to let me “geek out” on this bit of networking history.
