Optical reflectometer Yokogawa AQ1200

Optical reflectometer Yokogawa AQ1200 is the latest model of optical reflectometers Yokogawa, even more compact and lightweight.

Like the other models of Yokogawa reflectometers it provides high measuring speed and accuracy due to intelligent software optimized for measurement of networks of different architectures, and outstanding technical characteristics of the device. Small size and light weight make it ideal for measurements in the field conditions.

There are also many auxiliary features and functions (in the form of factory-set options), which greatly extend the reflectometer capacities.

Application features:

AQ1200A (1310 nm/1550 nm) is a model with standard operating wavelengths for provision of telecommunication services. Used at construction and operation of optical lines.

AQ1200B (1625 nm), AQ1200C (1650 nm) are models with operating wavelengths (1625 nm and 1650 nm) for servicing of optical lines. Application of the wavelengths different from the operating wavelengths of communication services, ensures minimum effect on those services when operating without service interruption. Special optical filter built into the reflectometer weakens influence of communication signals on the reflectometer measurement accuracy.

Key features:

  • Compact size and light weight (size - A5 sheet, weight about 1 kg);
  • Event dead zone <0.8 m;
  • Optimized to make reflectograms in PON networks (models AQ1200A/PN and AQ1200B, C);
  • Measurement of optical power and loss in a fiber by means of an integrated source and meter (optional);
  • Auto detection of wavelength at measurement of loss in the fiber;
  • Automated measurement of attenuation of multi-fiber cable, and saving of results in tabular form;
  • Function of PON-meter (optional);
  • Source of visible laser light (optional);
  • Digital microscope to visualize the connector surface (optional);
  • Determination of damage at optical line (Fault Locator);
  • Remote control of reflectometer via Ethernet (optional) or via USB port;
  • Test of network connection (Ping-Test);
  • Interface and controls are similar with optical reflectometer Yokogawa AQ7275;
  • Russified.
