The project will grant Turk Telekom a major expansion of its telecommunications infrastructure to keep up with the country's growing demand for fast multimedia services. After pioneering FEC for submarine networks in 1991, Alcatel is bringing this unique technology to DWDM terrestrial systems. The new high-speed national backbone- connecting major cities across Turkey - will provide Turk Telekom with the first DWDM systems ever deployed in the country for commercial applications. Alcatel's state-of-the-art DWDM systems, part of the Optinex family of carrier-class transmission solutions, will be able to carry up to 32 channels at 10 Gbps and will operate with a capacity equivalent to 38 millions telephone conversations simultaneously. Alcatel's DWDM systems take advantage of the unequalled Out-Of-Band Forward Error Correction (OOB-FEC)technology, which tremendously improves the quality of the signal transmitted. Alcatel's FEC solution has already successfully carried live commercial traffic in a field trial performed over the Ankara-Istanbul link, 490 km long. This functionality enables Turk Telekom to drastically reduce its network costs, while, at the same time, enhancing the consistency of end-to-end services supplied to their customers. As part of the agreement, Alcatel will also supply its integrated network management platform, for both DWDM and SDH solutions, to optimize the traffic control and routing at all network levels, thus simplifying the overall network performance. "The Turkish telecom market scenario shows concrete signs of expansion", stated Jean-Marie Vansteenkiste, President of Alcatel's terrestrial network activities. "We are pleased to help Turk Telekom build the network of the future and play a major role in the rapidly growing Turkish Internet market thanks to our turnkey, leading-edge optical networking solutions." About Alcatel Alcatel builds next generation networks, delivering integrated end-to-end voice and data networking solutions to established and new carriers, as well as enterprises and consumers worldwide. With 120,000 employees and sales of EURO 23 billion in 1999, Alcatel operates in more than 130 countries. Alcatel is the only vendor to master all optical network elements, from optical components, optical fibers and DWDM systems to core routers and network intelligence, and from terrestrial to submarine solutions. Alcatel is also the only company to provide both terrestrial and marine services for the installation and maintenance of global, seamless optical networks. According to RHK's 2000 study, Alcatel holds the number two position in global optical transport market with 20% market share, distancing itself from all other competitors. RHK also reported that Alcatel reaffirms its number one position in submarine networks with 41% worldwide market share. Moreover, Alcatel claims to be the world leader in total terrestrial and submarine DWDM systems, in digital cross-connects, which contain the enabling technology for operators to offer high bandwidth services, and in SDH networks. Alcatel's optics business comprises terrestrial and submarine transmission systems, fiber optics and optical components. Alcatel has launched a new class of Alcatel stock which is intended to track the performance of Alcatel Optronics, the Company's optical component business. For more information, please visit Alcatel's Web site at www.alcatel.com About OptinexTM 1686 WM The OptinexTM 1686 WM system provided by Alcatel supports 32 wavelength channels and is upgradable to 64 channels working at different channel bit-rates up to 10 Gbps. Different wavelengths are used for different traffic signals along the same fiber route. High performances for very long multi-span applications are obtained through wide-band in-line amplifier and Forward Error Correction devices while optical add-drop capabilities, partially re-configurable, are used in the intermediate nodes for traffic partial termination. About Forward Error Correction (FEC) FEC is a technique by means of which redundancy (i.e. extra information)is transmitted together with transported data, using a pre-determined algorithm. Thanks to redundancy, the receiving device can detect and correct multiple bit-errors that may occur during transmission. The signal transmitted with FEC is more "robust", thus allowing operators to build up longer distance connections without the deployment of many repeater stations. Contact press@www.alcatel.com
