We talked about Texas Lone Star Network (TLSN) about two years ago when they upgraded their network with Cisco ASR 9000 Series routers. Since then the company, a consortium of 40 Rural Telecommunications Carriers in Texas has expanded quickly, growing from 3000 lit miles of fiber to over 6225 miles and now providing services next door in New Mexico. Their Cisco-based IP and DWDM fiber network offers wavelength, Ethernet, and SONET services to its consortium company members, along with national carriers, wireless providers, regional cable TV operators, colleges and the federal government.
With bandwidth forecasts continuing to expand they’ve recently made the leap to 100G, adding Cisco’s coherent nLightTM 100G technology to their existing ROADM-based network. TLSN installed Cisco 40G in the network two years ago. For TLSN the ability to easily deploy 100G without the need to re-engineer the network or install new fiber is critical to their business. This will support growing customer demand for multiple 10G service on-demand. One service TLSN offers which they call “TLSN Texas Waves®” bundles multiple 10G or 2.5G optical wavelengths together. This solution has been well received as an ideal alternative to service providers faced with the high cost of a dark fiber IRU, maintenance and DWDM electronics. With the coherent optical upgrade they’re now well positioned to offer 40G and 100G wavelengths. Read More »
It’s been a busy year (and by year, we mean fiscal year, which ends in a few weeks) for Cisco’s optical solutions team. We’ve had a number of customer announcements for our 100G nLight DWDM technology and most recently scooped up an award for our CPAK-based 100G transponder card. Service providers across the globe have responded positively to Cisco’s ability to extend 100G services across network that were engineered for 10G wavelengths, and with CPAK we’re reducing the space and power and increasing the density of 100G services in routers (CRS-X), data center switches (Nexus 7000), and optical transport equipment (ONS15454 MSTP).
The news for today centers on our latest customer announcement for our DWDM solution, Vectra S.A., one of the largest cable operators in Poland has deployed Cisco for their new national fiber optic backbone. The network is a nationwide ring, connecting nearly thirty cities around Poland, including Warsaw, Katowice, Wroclaw, Poznan, Radom, Bydgoszcz, Torun, and Gdynia. Read More »
Just on the heels of our Packet Optical Networking Conference last week in San Jose we’re thrilled to announce another network operator has selected Cisco to make the transition to 100G. Last time was in the upper mountain state of Wyoming. This time it’s DukeNet Communications, a leading regional fiber network provider offering data and high-capacity bandwidth services to enterprise, data center, government and carrier customers. Primarily serving the southeastern United States, DukeNet controls an 8,000 route mile fiber-optic network now capable of delivering 100 Gbps services using Cisco’s nLight™ coherent Dense Wavelength Division Multiplexing (DWDM) technology. The Cisco ONS 15454-powered solution provides Read More »
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?
The Visual Networking Index predicts we’re going to hit nearly a zettabyte of traffic by 2015. Applications such as video and cloud services are consuming bandwidth on the network to the point that 10 Gbps infrastructure is insufficient. Without question, 100 Gbps technology in the data center, network core and edge, and transport is a key enabler to remove bandwidth constraints. Cisco is leading the industry in 100Gbps technology across network architecture, and two major acquisitions recently in the 100 Gbps optical component space drive innovation, reduce costs, and improve performance for our customers.
The first acquisition was CoreOptics, a Digital Signal Processing solution designer which was completed in 2010. CoreOptics provides silicon technology to deliver 100 Gbps coherent optical signals on existing (10 Gbps) fiber infrastructure. This means customers can upgrade to 100 Gbps and beyond without incurring tremendous costs. They can do this regardless if their existing fiber network is Cisco, Alcatel, or Nortel/Ciena. It’s the best 100Gbps DWDM solution in the industry with ultra long haul distances (up to 3000 km, as validated by EANTC) and highest density (3x the competition). Even better, we’ve already shown that it’s capable of taking transmission to 400 Gbps and 1 Tbps super-channels in the future.
The second acquisition, Lightwire, is a silicon photonics company with technology to enable cost-effective, very high-speed optical interconnects using CMOS-based silicon photonic optical transceivers. In non-technical terms, “CMOS” (Complementary Metal-Oxide-Semiconductor) is the industry standard for manufacturing chips without need for exotic materials or processes. This means lower power consumption, higher densities, and lower costs, all of which are critical to reducing the operational cost and carbon footprint of data centers as they scale to 100 Gbps and beyond. With this technology in-house, the advanced silicon optical technology can be utilized across our entire product portfolio.
Our customers are very positive. We’ve announced a number of successful trials in our long-haul DWDM solution, including US Signal, Lumos, and SURFnet. Look for more to be coming soon!
