The Anritsu MW9076 series is a small and lightweight optical time domain reflectometer (mini-OTDR) for measuring loss and locating faults in optical fiber cables at fiber installation and maintenance. It has excellent basic performance specifications including a dynamic range of 45 dB and a world-beating backscatter dead zone of just 8 m. For the best price performance, the series includes four types of main frame, two types of optical channel selector unit and two types of display unit.

 

Features

  • 8 m short dead zone
  • Simple measurement of chromatic dispersion from one end of optical fiber
  • Measurement in 10 s (Full-Auto mode), 0.15 s real-time sweep

Performance and Functions

  • High dynamic range
    When using a wavelength of 1.55 µm, a point about 190 km distant can be measured.
  • Short dead zone
    Clearly measure up to near end by 8 m dead zone (back-scatter, SM unit)
  • Chromatic dispersion measurement
    The MW9076D has a built-in function for measuring chromatic dispersion even outdoors. The chromatic dispersion can be measured automatically over a wide range from 1300 to 1660 nm from one end of the fiber. The dispersion reproducibility is ±0.05 ps/(nm · km)* and the dynamic range is 30 dB. The MW9076D can be operated from an external PC using remote commands to measure the chromatic dispersion. For detail of the chromatic dispersion measurement, refer to the document of “product introduction MW9076 series Optical Time Domain Reflectometer”.
    *: Measured with 25 km of 1.3 µm zero-dispersion fiber (ITU-T G.652) at 1550 nm.
  • Fresnel reflection
    The far-end Fresnel reflection can be measured for four wavelengths (1310/1450/1550/1625 nm).
  • Group delay characteristics
    The fitting formula supports cubic or quintic Sellmeier, and polynomials can be applied to various types of fibers.
  • Chromatic dispersion characteristics
    The zero and total dispersion can be displayed along with the delay, dispersion and dispersion slope at 0.1 nm steps.
  • High-speed measurement
    It takes only 10 seconds to measure and display the waveform and connection loss on one screen. Just one press of the Start key is all that is needed to make measurement.
  • Full automatic mode
    Measurement results are displayed by simply pressing the Start key. All complicated settings of distance range, pulse width, attenuator, and maker can be automatically executed. Measurement speed in this mode was significantly increased. When the wavelengths are set to ALL, wavelengths are automatically changed.
  • Repeated measurement
    A series of operations, such as measurement, wavelength switching, data saving, optical channel switching, and next optical fiber measurement, can be executed automatically under preset measurement conditions. This mode is ideal for measuring a multi-core optical fiber.
  • Waveform comparison function
    Measured and saved data can be compared on the same screen. In addition, differences can be displayed as a waveform for simple observation of distance and level differences. This is useful for checking aging changes or comparing several fibers.
  • Warning level setup function
    In automatic measurement mode, an event warning value can also be set in addition to a detection threshold value. For example, the threshold value can be set to the acceptance level, and warning value to a pass/rejection decision level. In this case, all events will be detected, and those exceeding the warning value are displayed in another color, therefore, enabling the operator to easily identify possible “borderline” events.
  • Communication light check function
    When measuring a fiber in service, there is a possibility of mis-measurement by an OTDR. To guard against the risk of mis-measurement, this check function checks for the presence of light other than the OTDR optical measurement pulse.
  • Visible LD
    A 635 nm visible LD option is available for the detection of breaks and loss points along the fiber to be measured.
  • VGA output terminal
    The VGA connector outputs the screen interface to a CRT monitor, which is very useful for production-line applications.
  • Large internal memory
    About 18 MB internal memory is provided as standard. The following table shows the number of waveforms which can be saved in each media.
