Sprint of Overland Park, Kansas, an approximately $5 billion-capitalised, 60,000-employee provider, mainly in the U.S., of wireless and wireline communications services, which:
Operates two wireless networks serving nearly 51 million customers, supporting mobile data services and instant national and international push-to-talk capabilities, plus a global Tier 1 Internet backbone network.
Has strategic alliances with Alcatel-Lucent, Cisco, HP, IBM, Microsoft, Nortel and Northrop Grumman.
Announced that, in collaboration with:
The TAT-14 cable system consortium, comprising approximately 40 international telecommunications carriers, and specifically TeliaSonera of Stockholm, Sweden, operator of the TAT-14 cable landing station in Denmark.
Cisco Systems, developer of the CRS-1 routing system.
StrataLight Communications of Los Gatos, California, an approximately 200-employee specialist in the integration of IP and optical technologies and a supplier of 40 Gbit/s line-side optical subsystems and dispersion compensation modules, currently in the process of merging with Opnext of Eatontown, New Jersey.
It has completed a technology trial of the first "alien" wavelength (a wavelength generated by a device external to the system) OC-768 / STM-256 40 Gbit/s transatlantic IP link between New York and Luleå, Sweden.
In total spanning a more than 9,000 km fibre link, the trial:
Traversed a 7,630 km section of the trans-Atlantic submarine TAT-14 cable system between Sea Girt, New Jersey and Blåbjerg, Denmark.
Marks the first time, Sprint claims, that an OC-768 40 Gbit/s signal has been transmitted over a submarine cable using a single wavelength and existing DWDM systems.
Involved TeliaSonera International Carrier providing support and optical backhaul from the European cable landing station for TAT-14 to Stockholm, and SUnet, the Swedish research and education network, providing the optical path to Lulea in the north of Sweden.
Used a system based on Cisco's CRS-1 with IPoDWDM technology to generate the long haul signal, in which the CRS 1 emitted a coloured 40 Gbit/s wavelength that was fed directly into existing 10 Gbit/s DWDM transmission equipment.
Involved close collaboration between Cisco and StrataLight Communications on the integration of IP and otpical technology.
Sprint Chief Information and Network Officer, Kathy Walker, stated:
"TAT-14 and Sprint were the first to transmit data at 10 Gbit/s, OC-192 speeds across the same path in 2001".
"Sprint and TAT-14 are making history again...by transmitting 40 Gbit/s over an existing 10 Gbit/s DWDM system".
Ross Saunders, GM for Next Generation Transport at StrataLight, was quoted as saying:
"This trial demonstrates the ability to multiply the transmission capacity of existing trans-oceanic submarine systems by four times simply by upgrading the end-points only".
"This can provide significant capital savings for service providers versus deploying new submarine cable systems".
While Peter Lothberg, an independent Swedish networking consultant from Stupi (Svensk TeleUtveckling & Produkt Innovation) of Karlstad, Sweden, remarked:
"Carrier-class routers, which integrate optical DWDM transport technology with packet processing, are the driving innovation behind the significant gains in network efficiency and cable system asset value".
"The road to greater success will continue to be paved by router designs optimised for improved optical transport".
