Artel's DigiLink 9000 Multichannel Video Transmission System Helps Providers Boost Bandwidth Capacity to Enable Enhanced Video Services.Business/Technology Editors SUPERCOMM 2000 MARLBOROUGH, Mass.--(BUSINESS WIRE)--May 30, 2000 DigiLink 9000 transports 256 QAM (1) (Quality Assessment Measurement) A system used to measure and analyze voice transmission. (2) (Quadrature Amplitude Modulation) A modulation technique that employs both phase modulation (PM) and amplitude modulation (AM). , MPEG-2 and digital video over a single fiber optic link Artel Artel (Russian: арте́ль) is a general term for various cooperative associations in Russia, historical and modern. today unveiled a new member of its DigiLink fiber optic video transmission product family that enables service providers to offer enhanced video services by squeezing more bandwidth out of their existing networks. Artel's DigiLink 9000 Multichannel Transmission System can transport up to eight channels baseband video/audio or 256 quadrature amplitude modulation See QAM. Quadrature Amplitude Modulation - (QAM) A method for encoding digital data in an analog signal in which each combination of phase and amplitude represents one of sixteen four bit patterns. This is required for fax transmission at 9600 bits per second. (QAM) over a single fiber optic link. DigiLink 9000's two rack unit (2RU), scalable optical architecture integrates with International Telecommunications Union See ITU. (body, standard) International Telecommunications Union - (ITU) ITU-T, the telecommunication standardisation sector of ITU, is responsible for making technical recommendations about telephone and data (including fax) communications systems for PTTs and suppliers. (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. ) standard dense wavelength division multiplexing See WDM. (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 ) technology for bandwidth efficient cable television (CATV (Community Antenna TV) The original name for cable TV. It used a single antenna at the highest location in the community in order to deliver a quality signal to homes in areas with hilly terrain or other interference. ) and telecommunication video service delivery. The DigiLink 9000 accepts any channel combination of baseband video/audio, IF or QAM signals. With support for 256 QAM, the DigiLink 9000 enables expansion of CATV and telecommunication offerings such as video on demand (VoD). Integrating with DWDM transport equipment such as Artel's MegaWav DWDM or third party DWDM equipment, the DigiLink 9000 offers highly bandwidth efficient digital TV (DTV (Digital TeleVision) Transmitting TV using digital signals. The major DTV standards are ATSC (North America), DVB (Europe) and ISDB (Japan). All three use MPEG-2 video compression and Dolby Digital audio compression. DVB and ISDB also include MPEG audio compression. ) and VoD service solutions. Working together with the MegaWav DWDM product, the DigiLink 9000 can use the 256 QAM functionality to transport more than 1000 channels of MPEG-2 TV-quality video across 120km on one fiber. The DigiLink 9000 surpasses the RS250C specification, providing telecommunication service providers with powerful short-haul baseband video/audio delivery of TV1 services. The DigiLink 9000 is fully interoperable with ITU-compliant equipment, is new equipment building standards (NEBS) level three compliant and uses ITU standard laser options. Artel will demonstrate DigiLink 9000 at SUPERCOMM 2000 at booth #5351 Hall F, Atlanta, Georgia from Tuesday, June 6th to Thursday, June 8th, 2000 and at Cable-Tech Expo at booth #646, Las Vegas, Nevada Monday, June 5th to Wednesday, June 7th, 2000.
