Short for electronic dispersion compensation, EDC technology is supported by the Optical Internetworking Forum (OIF) – a group currently defining a 10 Gbps interoperability specification targeting optical links. The transmission distance of this specification supports up to 120 km (2400 ps/nm), however, the maximum distance currently supported is specified at up to 80 km. To achieve this reach extension and lower the cost of optics on existing fiber links, EDC technology, as offered in the new BCM8105 optical networking chip, provides customers a seamless upgrade on existing OC-48 trunks beyond 80 km to OC-192, while enabling the use of low-cost optics without the need to re-engineer the link.
Short for erbium-doped fiber amplifier. EDFA is an optical repeater device that is used to boost the intensity of optical signals being carried through a fiber optic communications system. An optical fiber is doped with the rare earth element erbium so that the glass fiber can absorb light at one frequency and emit light at […]
Electronic Data Gathering, Analysis, and Retrieval system was implemented by the Securities and Exchange Commission (SEC) to do two things: 1) quickly process time-sensitive information of publicly-held companies and 2) provide investors with easier access to company information. EDGAR became available to filers on July 15, 1992, and as of May 6, 1996, all domestic […]
Acronym for Enhanced Data GSM Environment. EDGE is a faster version of GSM wireless service. EDGE enables data to be delivered at rates up to 384 Kbps on a broadband. The standard is based on the GSM standard and uses TDMA multiplexing technology.
Short for Electronic Data Interchange, the transfer of data between different companies using networks, such as VANs or the Internet. As more and more companies get connected to the Internet, EDI is becoming increasingly important as an easy mechanism for companies to buy, sell, and trade information. ANSI has approved a set of EDI standards […]
Extended Display Identification Data is a VESA standard data format that contains basic information about a monitor and its capabilities, including vendor information, maximum image size, color characteristics, factory pre-set timings, frequency range limits, and character strings for the monitor name and serial number. The information is stored in the display and is used to […]
