General Details

This FTTH series Optical Time Domain Reflectometer (OTDR) is an intelligent meter of a new generation for the detection of fiber communications systems. With the popularization of optical network construction in cities and countrysides, the measurement of optical network becomes short and disperse; Tarluz OTDR is specially designed for that kind of application. It’s economic, having outstanding performance.

This OTDR manufactured with patience and carefulness, following the national standards to combine the rich experience and modern technology, subject to stringent mechanical, electronic and optical testing and quality assurance; in the other way, the new design makes OT700 series more smart and compact and multi-purpose.

Whether you want to detect link layer in the construction and installation of optical network or proceed efficient maintenance and trouble shooting, OT700 Series can be your best assistant.

  1. Typical, backlight off, sweeping halted at 25℃, 12 hours typical continuous testing.
  2. Model S2 are integrated with optical filter, which allow them to test PON network online (by using 1625nm wavelength) and will not interrupt the fiber signal.
  3. Dynamic range is measured with maximum pulse width, averaging time is 3 minutes, SNR=1; the level difference between the RMS noise level and the level where near end back-scattering occurs.
  4. Event dead zone is measured with pulse width of 3ns; attenuation dead zone is measured with pulse width of 5ns.
  5. 1310/1550nm laser source uses OTDR1 port, and 1625nm or 850/1300nm uses OTDR2 port.
