Optical Fiber Ranger


Optical Fiber Ranger


Fiber Ranger is newly designed fiber optic tester, it aims at fiber fiber network installation, fiber network engineering acceptance and fiber network maintenance. It can detect fiber fault location more accurate and quick, and designed for field use. This fiber ranger is an economical tester instead of OTDR in the test and maintenance of fiber network.

Main Features

  • Easy to identify the faults location
  • Analysis reflection events and attenuation events automatically
  • Build-in visual fault locator function
  • Automatic Pulse Width Control design to ensure a convenient operation.
  • Up to 2500 measurement results can be stored in the unit.
