Optical reflectometer Yokogawa AQ7270

Description:

New OTDR-reflectometer Yokogawa AQ7270 proves than perfection has no boundaries! It has practically all the advantages of the previous model (Yokogawa AQ7260), but even more compact, lightweight and quick in use. AQ7270 is characterized by a record-breaking small dead zone of detection as of today – 0.8 meter. Within a few seconds the reflectometer is switched on and operation can be started, and the inline function of high-speed automatic testing enables the first simplified test to be carried out by pushing just one button. OTDR-reflectometer Yokogawa AQ7270 is designed to facilitate work under conditions of lack of time and free space, when density of information system and price for idle time are very high.

 

Advantages of the model

  • The shortest in the world today dead zone of detection - 0.8 m!
  • Ability to "download" and be ready for the first measurement within less than 10 seconds
  • Built-in function of high-speed automatic testing, high speed of all measurements
  • High precision of distance measurements and readout resolution (up to 1 cm)
  • Dynamic range up to 40 dB, length of the measured routes up to 400 km
  • Large screen which can be comfortable viewed from any angle
  • Universal Interface USB (types A and B) and Ethernet port, which allow connection of your computer, external storage devices, printer, etc.
  • Optional built-in printer for fast printing of reflectograms
  • Mode of the stabilized radiation source
  • Built-in auxiliary fiber bundle for testing of short lines
  • NiMH battery, designed for continuous operation of the device during 6 hours, with recharge time of less than 5 hours
  • Portable design: size of about 287 mm x 197 mm x 85 mm (WxHxD), weight only 2.8 kg
  • Ability to work at temperatures from 0 to 45 °C and relative humidity to 95%
