  • Dense Wavelength Division Multiplexer (DWDM)
    Dense wavelength division multiplexers (DWDM) use an optical (analog) multiplexing technique to increase the carrying capacity of a fiber network beyond what can be achieved with time division multiplexing (TDM) techniques. Different wavelengths of light are used to transmit multiple streams
  • Semiconductor Optical Amplifier in Coarse Wavelength Division Multiplexed Systems
    the wavelengths. The wavelengths span from 1260 nm to 1610 nm as shown in Figure 1. Since the wavelengths are 20 nm apart, it allows for the use of lower cost components like cooler-less DFB lasers, dielectric filter based multiplexers/demultiplexers etc. This not only reduces the cost of the optical components
  • Case Study: Sixteen Eyes Can See Better Than Two
    AICON 3D Systems GmbH is one of the world leading providers of optical camera based 3D measurement systems. The company located in Braunschweig, Germany, develops and distributes systems for the business areas of inspection and testing as well as car safety and tube inspection. The majority
  • EETimes.com | Electronics Industry News for EEs & Engineering Managers
    Corvis demos optical equipment to quell critics Corvis Corp. made back-to-back demonstrations of its optical routing switch and optical add-drop multiplexer equipment at the recent National Fiber Optics Engineers Conference and NetWorld+Interop Fall, hoping to quell critics who say the company's
  • Automated Signal Switching Primer
    Routing electrical and even optical signals from one source to another requires an overall understanding of the application, signals being switched and finally an understanding of how to select a switching solution that helps maintain signal integrity at a reasonable cost. Some of the main Issues
  • Measuring the long haul
    . But where stainless tape is punched with a coded pattern and read by an optical sensor, the new method makes use of an extruded aluminum profile containing buried magnets. A special Hall-effect sensor detects the magnets and determines absolute position. These position multiplexer encoders, or Pomux
  • Fiber Optic Rotary Joints
    . Home | Company | LEED | News | Terms | Learning | Career | Contact. 609.895.9890 609.895.9552. TUTORIAL: Fiber optic rotary joints. The Fiberoptic Rotary Joint (FORJ) is the optical equivalent of the electrical slip ring. It allows uninterrupted transmission of an optical signal
  • Faraday Rotator Mirror and Michelson Interferometer
    the precursor of many important modern optic measurement techniques. The Michelson Interferometer, as it is called, is used to measure small optical path length changes. The classic Michelson Interferometer consists of two mirrors (one forming the reference arm and the other the probing arm
