Alcatel Telecom Introduces Broadband Solutions -- 10 Gigabits and Beyond -- For The Next Step in Network Evolution.RICHARDSON, Texas--(BUSINESS WIRE)--June 21, 1996--Alcatel Telecom is unveiling it Alcatel 16192 SM 10 Gbit/s SONET (synchronous optical network (networking) Synchronous Optical NETwork - (SONET) A broadband networking standard based on point-to-point optical fibre networks. SONET will provide a high-bandwidth "pipe" to support ATM-based services. ) multiplexer and 160 Gbit/s wave division multiplexing (spelling) wave division multiplexing - A common misnomer for wavelength division multiplexing. (WDM (1) (Wavelength Division Multiplexing) A technology that uses multiple lasers and transmits several wavelengths of light (lambdas) simultaneously over a single optical fiber. ) technology at Supercomm '96 in Dallas. With these tools, carriers can increase their current network capacity exponentially and maximize the use of existing fiber optic facilities at the same time. "Alcatel's new 16192 SM and WDM technologies complement each other to create the network of the future," said Joe Bass, Alcatel Telecom Vice President and General Manager -- Lightwave Products. "16 channel WDM and the 16192 SM must be used together, not as alternatives, to achieve the highest possible bandwidth of 160 Gbit/s. This type of bandwidth means a whole new world of greater, faster and more efficient services, particularly in the video and ATM areas." For comparison purposes, the 160 Gbit/s rate -- 64 times higher than current commercial rates at 2.5 Gbit/s (OC-48) -- allows simultaneous transmission of 2 million telephone conversations or, alternatively, 64,000 television channels. The Alcatel 16192 SM features one system architecture that fits all applications and that requires no expensive hardware upgrades to reconfigure. Flexibility and simplicity in the Alcatel 16192 SM result from using only three functional subsystems to support any configuration; the Line Subsystem, the Optical Tributary Subsystem, and the Communications Subsystem In telecommunication, a communications subsystem is a functional unit or operational assembly that is smaller than the larger assembly under consideration. Examples of communications subsystems in the Defense Communications System (DCS) are (a) a satellite link with one Earth . Architectures supported include: terminals, add/drop multiplexers, repeaters, optical hubs, and 2-Fiber and 4-Fiber Bi-directional Line Switched Rings. The Alcatel 16192 SM's optical OC-12 (622 Mbit/s) tributaries support any combination of U.S.-standard STS-1, STS-3c, or STS-12c payloads and the European equivalent STM-1 and STM-4 payloads. Users can change the payload mix at any time without the need to replace hardware or download software. For carriers looking to significantly maximize fiber usage, the Alcatel 16192 SM offers spectrally narrow transmitters with wavelengths that conform to Verb 1. conform to - satisfy a condition or restriction; "Does this paper meet the requirements for the degree?" fit, meet coordinate - be co-ordinated; "These activities coordinate well" the ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. channel plan for dense WDM applications. The Alcatel 16192 will support the 200 GHz channel spacing The amount of bandwidth allotted to each channel in a communications system that transmits multiple frequencies such as fiber optics. It is measured as the spacing between center frequencies (or wavelengths) of adjacent channels. See guard band. plan that is emerging as a viable, cost-effective solution. Alcatel Telecom researchers have achieved 160 Gbit/s transmission rates by using WDM for 16 optical carriers of 10 Gbit each. The 16 different wavelengths are transmitted and propagated simultaneously using a single fiber, separated, and recovered at the end of the line. The Alcatel 1610 OA (Release 4.0) fluoride-based optical amplifier A device that boosts light signals in an optical fiber network. Unlike regenerators, which have to convert light to electricity in order to amplify it and then convert it back again to light, the optical amplifier amplifies the light signal itself. figures significantly in this achievement. Fluoride-based amplifiers have signal-to-noise performance advantages over silica-based amplifiers across a wider bandwidth, making possible 32 channel WDM. Alcatel Telecom's success in transmitting at 160 Gbit/s over the same type optical fiber used today around the world offers operators a realistic and profitable way of increasing bit rates in order to satisfy market needs. WDM enables operators to increase capacity significantly, without having to replace networks in which they already have significant investment.
