AOI Announces Availability of 8 Wavelength CWDM Lasers.Business Editors/High-Tech Writers SUGAR LAND, Texas--(BUSINESS WIRE)--June 30, 2003 Applied Optoelectronics Inc., a leading manufacturer of laser diodes for fiber optic communications systems, announced today the availability of lasers for Coarse Wavelength Division Multiplexed (CWDM (Course WDM) An optical transmission method that is used for shorter distances than dense WDM (DWDM). Also known as "wide WDM," CWDM transmits fewer channels and uses wider spacing between the channels for distances up to 60 km. Wider spacing up to 25 nm, compared to 1. ) systems. CWDM is an emerging standard for multiplying the bandwidth that can be transmitted on an optical fiber. The standard is a low-cost alternative to expensive 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 ), offering a route to increased bandwidth without expensive DWDM components or additional fiber installation. AOI's CWDM lasers are offered in three versions. The first version, the DFB-1xxx-C5-x-2.5 series, is designed for digital transmission applications, with data rates of up to 2.5 gigabits per second. It is intended primarily for metropolitan area networks and high-speed access applications, including deep-fiber architectures. The second version, the DFB-1xxx-C5-x-A series, is designed for analog transmission applications, especially hybrid fiber-coax (HFC 1. (networking) HFC - Hybrid Fiber Coax. 2. (hardware) HFC - hydrofluorocarbon. ) networks. The lasers are particularly well suited for multiplying the available bandwidth in the analog return-path portion of a cable-television network. The third version is available in both a temperature-stabilized package, the DFB-1xxx-BF-xx-A2 series, and an inexpensive un-cooled package, the DFB-1xxx-C5-x-A4 series. These lasers are intended for use in direct analog transmission of signals up to 2.4 GHz, such as in antenna remotes for mobile telephone networks. "As network operators search for more cost-effective means of utilizing their existing fiber plants, CWDM technology enables the addition of capacity without large capital expenditures," said Stefan Murry, director of sales and marketing at AOI AOI Area Of Interest AOI Automated Optical Inspection AOI Art of Illusion (3D modeling software) AOI Associated Oregon Industries AOI Angle Of Incidence AOI Age of Innocence (David Hamilton book, also a band) . "Particularly in cable television networks, where return-path bandwidth is often constrained, AOI's new CWDM components offer the flexibility to add additional bandwidth incrementally, thereby reducing the cost of required capital equipment." All of AOI's laser products are manufactured in its own epitaxy epitaxy Process of growing a crystal of a particular orientation on top of another crystal. If both crystals are of the same material, the process is known as homoepitaxy; if the materials are different, it is known as heteroepitaxy. facility and wafer fab near Houston. The facility is ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. 9001:2000 registered to ensure the highest quality standards. Additional information is available at: www.ao-inc.com |
