  • Highly accurate and long-term stable thanks to the usage of an external reference optical channel

  • Simultaneously measures optical power levels in each optical channel (dBm) and attenuation change (dB), and calculates the fiber attenuation coefficient change (dB/km)

  • IIT-nOT operating control, representing, storing and data processing are provided by the PC 

  • Records measurement results on schedule or manually

  • Simultaneously measures up to 16 fibers

  • High long-term stability

  • Can store data in the Excel format

  • The modules can be in different places when measuring the optical fiber
