In case you might have missed it (or don’t read Russian) I wanted to call out two newsworthy items related to Cisco and 100G technology.
Last week at CiscoLive! London we announced the availability of 100GE interfaces on the Nexus 7000 to reduce bandwidth bottlenecks in the data center and help our customers meet the demands of emerging cloud computing applications. With this announcement Cisco becomes the only vendor in the industry offering an end-to-end 100G solution which includes the core (CRS), edge (ASR 9000), data center (Nexus 7000), and coherent DWDM optical transport (ONS 15454 MSTP). Furthermore we’re also one of only a handful of companies in the networking industry that owns (through our acquisition of CoreOptics) the underlying technology needed to make 100G (and beyond) a cost effective reality. With the high forecasted growth rate of the global Internet we believe that our customers will strongly benefit from the unique breadth of our solution to meet both their business and technology requirements.
The second announcement comes out of Russia with the latest live trial of Cisco’s coherent DWDM technology. Russian networking operator Bashinformsvyaz successfully validated the performance of our ONS 15454 MSTP solution between two cities in the Republic of Bashkortostan -- Ufa and Sterlitamak. The longest test performed was at a distance of 1296 km, although it has been tested to work without regeneration or the need for Raman amplification at distances beyond 2000 km. Most importantly for the customer was the fact that the 100G signals had no negative impact on existing 10 Gbps services (also being carried using the ONS 15454), demonstrating to Bashinformsvyaz the ability to cost-effectively add capacity at 100G over the existing fiber plant. The successful results were no surprise to Cisco Systems Engineer Boris Chervakov who noted that “To date, 100 Gb/s DWDM-transponders have Cisco’s industry-leading specifications for performance and port density that allows the introduction of technology to 100G networks of any complexity.”
Shaukat Barievich Yanyshev, Technical Director of Bashinformsvyaz said that:
“In preparation for the core network backbone to test traffic at speeds of 100 Gbps we are mainly concerned about the problem of growing polarization mode dispersion (PMD), which arises due to the uneven geometry of the profile of the core single-mode fibers, laid at various times over the past 16 years. We’ve done specific preparatory work with the linear element of the physical layer (welding joints, dry contacts, eliminating the dynamic loads, bends, controlling the PMD). Resulting measurements of the test traffic at 100 Gbps collected over a 24-hour period showed zero percent packet loss.”
If you are going to be attending the OFC/NFOEC show in Los Angeles, March 6-8, 2012 you’ll have a chance to see the ONS 15454 100G solution for yourself. Please contact your Cisco account manager to arrange a meeting.
In any case stay tuned for more news from Cisco on 100G – we’ve got more good stories to share soon!
