Cisco Going the Distance . . . 3,000 km

 Cisco is really stretching it out when it comes to 100 Gigabit DWDM.

Today, Cisco announced successful demonstration and validation of its coherent 100 Gigabit (100G) DWDM solution exceeding 3,000 km in reach.  

Cisco is the first to deliver 100G at 3,000 km distances without the need for complex Raman optical amplification technology or signal regeneration signals.  This distance is 50-percent further than any non-Raman alternative solution on the market today.

What does this mean?  

Well, by eliminating the need for Raman amplification, regeneration and dispersion compensation, carriers can add 100G services on top of existing infrastructures originally designed for 10G technology.  That means better investment protection and a simpler network upgrade process.

The Cisco solution has been tested at a number of service providers and research networks, including US Signal. The performance was also validated by EANTC, the European Advanced Network Test Center.

No Slowing for the Holidays

The end-of-year holiday season is traditionally positioned as a chance to slow down and re-charge, but Cisco’s industry-leading products for service providers didn’t get the memo.   Their momentum continued unabated.

Just two days before Christmas, Cisco announced that Dutch service provider KPN has chosen the Cisco CRS-3 multi-chassis carrier routing system, which will be deployed at the heart of KPN’s Internet peering network. The CRS-3 solution will transport all of KPN’s IP traffic to the Internet as part of KPN’s Internet Cluster Environment (ICE).

Not long before, Verizon announced that its IP network, one of the most advanced communications networks in the world, will be upgraded in the first half of 2012 with the Cisco CRS-3 to enable new services and meet growing traffic demands in several key U.S. markets, including Atlanta, Boston, Chicago, Dallas, Los Angeles, New York and Seattle.

As for the ASR 9000 edge routing system, Fibrenoire, a service provider offering Internet and private network services over an optical fiber network in Quebec and Ontario, has completed implementation of an end-to-end Cisco Carrier Ethernet System covering the Quebec City, Montreal and Toronto regions. Fibrenoire’s network is based on the ASR 9000.

Additionally, Next Communications, a Miami-based voice and video provider, has deployed Cisco technology for its IP Next-Generation Network. Integral to this will be deployment of the ASR 9000 and ASR 1000 routers for 100GE port capacity and greater resiliency.

And a couple of other interesting news items:

Paying Attention to TCO can save the Government Millions in Transport Costs

December 14, 2011 at 3:32 pm PST

I’ve been thinking a lot about TCO recently and ways we can help the Government maximize the investment of our tax dollars. By chance, I ran across this incredible White Paper written by one of our top Optical Engineers  entitled “Government Transport Networks:  Minimize Lifetime Costs”.

It’s a good read, and if you are a Network Architect making purchasing decisions in this area, I would highly recommend it.  In fact, if you have any further questions on any of the data presented please reach out to me directly and I’ll put you in touch with the author.

This paper makes the case that transport networks represent a significant portion of government IT costs and is often overlooked in terms of TCO.  It guides the reader through the various Network Deployment Models (private, managed private, hybrid) and the benefits  in real dollars by going with one approach over another.

Transport networks affect government operational costs at least as much as campus or data center networks, and carefully selecting the platform can result in significant savings. In summary, a well-planned transport architecture can help agencies avoid the considerable expense of upgrades as they accelerate adoption of business video and virtualization. In contrast, a platform with lower upfront costs may have a shorter lifespan and require IT teams to continually add overlay networks that increase costs and management complexity.

So “caveat emptor” when considering your next network purchase.

Transoceanic Fiber Cable: a Luminary Discovery

By Steven Shepard, Contributing Columnist

This story is a bit more technical that what I’ve previously shared. That said, I’ll link to some definitions for you non-technical readers — I promise, this one is going to be worth the extra effort. However, a bit of technology is required in the telling — so please bear with me.

Let’s step back in time. The first transoceanic cables used copper wire as the conductor that carried signals between continents. Unfortunately, the technology at the time was such that the cables were extremely bandwidth-limited and could therefore support a very small number of simultaneous conversations.

Furthermore, the physics of metallic transmission dictated that the transmitted signals would decay over distance, making it necessary to amplify and/or regenerate the transmitted signal periodically. This was costly, and required additional circuitry to filter electromagnetic interference and increase the signal level every few thousand feet.

The Real (Networking) Stars of Los Angeles

Cisco 100 Gigabit  Ethernet @ OFC/NFOEC 2011Early this month the stars in Los Angeles weren’t walking the Red Carpet, nor Tweeting about #winning, nor trashing their dressing room. Instead they were on the blue carpet of the Los Angeles Convention Center at the OFC/NFOEC 2011 show. A few themes clearly stood out regarding the challenges faced by network operators trying to address the bandwidth growth driven by video and collaboration technologies:

  1. Investment Protection: The relentless need to optimize infrastructure investments
  2. MPLS-TP:  Deployment of packet-based technologies for future transport networks
  3. Interoperability: Why scaling to 100 Gig in an interoperable manner will be critical
  4. Optical Component Innovation: How coherent optical technology, flexible spectrum and component modules will be leveraged in future optical networks

Investment Protection: As providers continue to expand their converged backbone transport networks, they are carefully scrutinizing expenses. Bandwidth growth is driving the expansion and various technology approaches are being discussed to tackle it: efficient wavelength optimization, optical switching, optical bypass, packet switching, packet bypass, label switching and others. Some implementations focus on creating new platforms for each technology function. An ideal approach conserves existing investments without compromising performance. For example, label switching is a function that is fundamental to the core and is an easy, incremental deployment within established platforms. Adding this capability to established platforms makes best use of existing infrastructure and avoids new qualification cycles.

MPLS-TP:  Today MPLS is evolving the transport architecture with MPLS-TP and recently implemented in Cisco’s new Carrier Packet Transport (CPT) platform. The CPT attracted the interest of many customers, and we heard a number of positive comments at the event:
