Specification :

Features
Providing simultaneous measurement at all three wavelengths on the fiber ( 1490nm, 1550nm, 1310nm )
Used in Burst mode measurement of 1310nm upstream
1000 measurement items can be saved in PON power meter or computer for data review.
PON power meter offers up to 10 different threshold sets in total; Three status LEDs represents different optical signal conditions of Pass, Warn and Fail respectively.
User self-calibration can be performed and ? ? Default? ? mode can be retrieved in computer through the software.
PON SC standard connector, easy to test
