Product Description


This OTDR is designed for user-friendliness and portability. It is equipped with a 3.5-inch (88.9 mm) color LCD touching screen. This instrument is mainly used in applications such as fiber testing and troubleshooting. It is also used in optical fiber cable attenuation. It provides the loss distribution curve of the optical fiber and cable as well as the loss of two points and the joint loss. This tool comes with an additional functionality of VFL (Vision Fault Locating).

  • Test the distance between two points and dynamically display the distance between two cursors
  • Test the loss between two points and the loss constant of the optical fiber and cable
  • Test the joint loss
  • Auto-optimization and quick response
  • Automatic search for the event points
  • Ability to store data into the disk, retrieve it and display it on the screen
