MOT-940 Mini OTDR series

MOT-940 Mini OTDR series

The MOT-940 Mini optical reflectometer series comes in a compact metal housing with all functions as a full OTDR.

  • The reflectometer determines the distance to reflecting and non-reflecting events and measures insertion loss of optical line and attenuation loss.
  • In addition, the MOT-940 is fitted with an optical power meter and a visible light source.
  • The internal memory allows the storage more than 1000 traces, USB interface is designed for saving of data onto USB flash memory. 
  • Power supplying is ensured with inbuilt rechargeable Li-Ion battery, which provides long term working time. 
  • The MOT-940 is designed for testing single mode and multimode optical fiber parameters in the process of installation, operation and maintenance, respectively the fault location in field conditions.
