MAY600 OTDR is a new generation of portable and intelligent measuring instrument for testing fiber optic communication system. It adopts 5.6 inch color touch screen, button/touch operation, internal integration of eight major functional modules, intelligent power-saving management, and 20 hours long standby, which help customers effectively solve the field testing and maintenance.

It is mainly used to measure the length, loss and connection quality of optical fibers and cables, and can be widely used in engineering construction, network maintenance and testing, emergency repair, and the development and production of optical fibers and cables.
The highest 45dB dynamic range can penetrate optical splitters easily for PON network testing.
The design concept of multi-functional integration, precision testing and convenient operation makes the field testing simple.


  • Integrated design, smart and rugged
  • Shockproof, outdoor enhancement

  • Automatic and manual test function
  • Visual Fault Locator (VFL) function
  • OTDR Viewer software for data analysis


  • FTTX testingwith PON networks
  • CATV network testing
  • Access network testing
  • LAN network testing
  • Metro network testing
  • Laband Factory testing
  • FTTA troubleshooting

2. Optical Power Meter (OPM)
3. Optical Light Source (OLS)
4. Visual Fault Locator (VFL)
    Visual Fault Locator uses red laser of 650nm to locate broken fiber point and test fiber continuity.
5. Fiber Optic Microscope (FIM)
    Fiber Optic Microscope is used to check fiber optic connector endface. The inspection probe is sold seperately.
6. Event Map
    Event Map is similar to EXFO’s iOLM function, which can display events in user-friendly icons.
7. IL Testing
    OPM and OLS can be opened at the same time to test insertion loss.
8. Report Print
    PC software helps print out OTDR test reports.
