With the development of FTTH PON network, a lot of optical ports are not used and wasted. Carriers need to check the idle optical ports to reduce the waste and fully use the idle optical ports in the future. However, by manual checking is complicated and inefficient and will bring trouble to users.

Engineers don’t need to enter into the user’s house and only in the corridor connect fibers in Optical Distribution Box with MAY57 PON Network State Tester to check the resources of idle optical ports and analyze the status of OLT and ONT in PON network intelligently. In this way, it will help carriers manage network resources efficiently.

MAY57 PON Network State Tester integrates PON Network State funtion, PON Power Meter, VFL, RJ45 Cable Sequene, Length and Tracker in one tester.


  • Check idle optical ports in PON network
  • It can carry out synchronous measurementof voice, data and video signal in BPON/EPON/GPON.
  • Providing simultaneous measurement for all three wavelengths inthe fiber (1310nm, 1490nm, and 1550nm)
  • Used in burst mode measurement of 1310nm upstream.
  • Pass/Fail thresholds for 1310/1490/1550nm can be set seperately
  • User calibration for 1310/1490/1550nm respectively
  • High definition TFT true color screen
  • Auto-off function (close, 10min, 30min and 1 hour) and backlight (25%, 50%, 75% and 100%) can be set
  • 1,000 measurement items can be saved in PON power meter for data review.
