CVI Offers Polarizers and Waveplates for DWDM.Business Editors/High-Tech Writers ALBUQUERQUE, N.M.--(BUSINESS WIRE)--Nov. 13, 2000 CVI CVI C (Language) Virtual Instrument CVI Clinical and Vaccine Immunology (journal) CVI Chronic Venous Insufficiency CVI Coastal Vulnerability Index CVI Canaan Valley Institute Laser Corp.'s Polarizing Beamsplitter Cubes and First Order Waveplates offer extreme 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 versatility to the expanding market of fiber optics fiber optics, transmission of digitized messages or information by light pulses along hair-thin glass fibers. Each fiber is surrounded by a cladding having a high index of refractance so that the light is internally reflected and travels the length of the fiber . Using proprietary CVI thin film technology, Polarizing Beamsplitter Cubes provide 30dB C-band extinction ratio and less than -0.2dB insertion loss. Ranging from 1529nm to 1565nm in wavelength, they are especially effective as C-band, L-band, 1300nm band, EDFA (Erbium-Doped Fiber Amplifier) A device that boosts the signal in an optical fiber. Introduced in the late 1980s, the EDFA was the first successful optical amplifier. variable attenuators, and optical isolators when combined with First Order Waveplates. They can also be used in many other DWDM applications, including beam combining, beamsplitting, and EDF (algorithm) EDF - earliest deadline first. optical amplifier pumping. CVI's First Order Waveplates are a half of a wavelength or a quarter of a wavelength polarization retarders used in DWDM systems, isolators, and variable attenuators. An epoxy free, ultra thin design provides a C-band retardation tolerance of one hundredth of a wavelength -- the lowest temperature sensitivity available. L band, 1300nm band, and EDFA wavelengths are also available. Polarizing Beamsplitter Cubes as well as low insertion loss First Order and Zero Order configurations are available in a variety of dimensions from 1mm to 50mm to meet your DWDM system requirements. |
