The MW9076 mini-OTDR series can perform a measurement three to five times faster than the well received, conventional MW9070B. Three and four-wavelength OTDRs are included among the new product lineup. The four-wavelength OTDR can measure the chromatic dispersion characteristics from one end of an optical fiber. Two types of color displays with high resolution (5cm) and many sampling points (50000 points) are available for indoor and outdoor use. The MW9076 series shows superior basic performance that enables a wide dynamic range and a short dead zone. It supports the construction and maintenance of the optical fiber cables. Moreover, using this OTDR, it is possible not only to quickly charge a lithium-ion battery but also to indicate the remaining battery charge.

  • 45 dB high dynamic range
  • Short 8 m dead zone
  • Simple measurement of chromatic dispersion from one end of an optical fiber
  • Measurement in 10 s (Full-Auto mode), 0.15 s real-time sweep
  • 5 cm high resolution, 50,000 sampling points
  • 8.4 inch TFT-LCD color display

Explanation General purpose OTDR for mid-distance SM optical fiber installation and maintenance. Offering superior cost performance. High performance OTDR: Ideal for users requiring long-distance optical fiber installation and maintenance. High performance three wavelength OTDR for testing at both the two standard SM window, but also the 1625 nm window used for fiber monitoring. A four wavelength OTDR with superb wavelength accuracy that can be used for conventional OTDR applications and chromatic dispersion measurement of high speed / high capacity transmission links.
