Product Description


GaoTek Optical Time Domain Reflectometer is equipped with Anti-seismic and Shock Proof feature which makes it suitable for field operations. It also examines out-of-band 1650 nm OTDR testing and detect problems with existing fiber. This OTDR can meet the requirement of FTTx online testing,malfunction elimination and building network testing, able to identify the splitter and the fibers end. It can store a wide range of more than 10000 curve information in its memory database.

Key Features:

  • Anti-seismic, shockproof and appropriate for field operation.
  • 1625 nm wavelength with belt filter, support FTTx online test.
  • Quick Start function in 3 seconds measuring immediately
  • 86 inches event blind zone, simple test of fiber patch cord.
  • The maximum measure distance is 99.41 miles.
  • Can store more than Can choose various test modes: automatic / manual / average / real time
  • The High Capacity SD card can store more than 10000 curve information.
  • Low-power design, optical lithium battery.
  • VFL (Visual Fault Location) functions.
  • Multiple light outputs, FC as standard ST/SC, optional and exchangeable.
  • OTDR Viewer software for data analysis,edit and printing.
  • Handheld design, compact and lightweight.

1. The technical data describe the guaranteed performance of the instrument in the measurements based on typical PC connectors. They are not based on the uncertainty due to the optical fiber index of refraction.
2. The dynamic range (SNR) of 1 is measured based on the maximum pulse width and a mean time of 3 minutes.
3. Dead zone measurement conditions: The reflection strength is smaller than -45dB; the pulse width is 10ns for event dead zone measuring, or 50ns for attenuation dead zone measuring.
4. The uncertainty due to the index of refraction is not considered.
