Xtera Demonstrates World's First 10-Gbps Transmission with Raman Amplifiers in the S-band.Business & High Tech Editors ALLEN, Texas--(BUSINESS WIRE)--Feb. 13, 2001 Xtera Communications demonstrates multi-channel 10-Gbps transmission through standard single mode fiber using cascaded discrete Raman amplifiers Pronounced "ruh-mahn," it is a device that boosts the signal in an optical fiber by transferring energy from a powerful pump beam to a weaker signal beam. It relies on the interaction between light and atoms in the fiber. in the S-band Xtera Communications Inc. (www.xtera.com), the long-haul and ultra-long-haul optical networking Communications between computers, telephones and other electronic devices using light. An optical network is far more reliable and has far greater potential transmission capacity than networking in the electrical domain. See optical fiber. company that recently completed its second round of financing for $110 million, today announced the world's first 10-gigabit/second transmission through cascaded discrete Raman amplifiers in the S-band. The 16-channel transmission was a technological breakthrough, opening up bandwidth previously untapped by commercial optical networking products. Currently deployed dense wave division multiplexing (spelling) wave division multiplexing - A common misnomer for wavelength division multiplexing. (DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing ) systems transmit in the C-band (1530 to 1565 nm) and the L-band (1570 to 1610 nm). The Xtera eXpander System Integral is the world's first commercially available product to expand the usable bandwidth of fiber into the window between 1485 and 1525 nm, supporting 50 GHZ (GigaHertZ) One billion cycles per second. High-speed computers have internal clocks rated in GHz, and radio frequency applications transmit in this range. See MHz for an explanation of how GHz and MHz affect computer performance. See RF and space/time. spacing in the S-band. "The trial demonstrates Xtera's ability to leverage our intellectual property with the optical expertise of our development team to expand usable bandwidth on existing fiber," according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. Herve Fevrier, Xtera Vice President of Photonic Dealing with light (photons). See photon and photonics. Systems. "The innovative use of Raman amplifiers is a breakthrough in commercial applications of tested laboratory technologies. Getting more bandwidth out of existing fiber is far more cost effective for carriers than lighting new fiber. It is all about delivering the best cost per gigabit per kilometer." The trial used the Xtera eXpander to transmit 10 gigabits/second through dual-stage discrete Raman amplifiers. Xtera transmitted over 16 channels on standard single mode fiber (SSMF SSMF Standard Single Mode Fiber (Corning) SSMF Sewanee Summer Music Festival (Sewanee, TN) SSMF Space Station Millimeter Facility SSMF Space Station Microwave Facility ), showing a full range of wavelengths throughout the window of the S-band. The Xtera eXpander integrates into existing DWDM systems, providing new bandwidth capacity on existing fiber without requiring additional network elements to be deployed. The Xtera eXpander is the first in a series of System Integrals, turnkey subsystems that will enable telecom equipment manufacturers to speed their time to market with new features on systems they currently sell to carriers. These enhancements help system vendors become more responsive to the dynamic requirements and cost objectives now prevalent in today's service provider's network. Xtera's System Integrals bridge the gap between components/modules and full systems by proving fully functional network features that integrate into existing network elements. About Xtera Xtera Communications Inc., based in the telecom-technology corridor in North Texas, is applying a fresh approach to developing long-haul and ultra long-haul technologies and products for the all-optical network A communications network that works completely in the optical domain. It uses optical switches connected by optical fibers.
