1,It features a pass/fail LED indicator; it lets you set your own thresholds for absolute or relative loss measurements.
2,In Auto-Switching mode,automatically toggles between available wavelengths. you can store results for all wavelengths at once.
3,it offers over 40 calibrated wavelengths, including all CWDM wavelengths.
4,Power fluctuations can be measured using its "Keep Min/Max Power" function.
5,Passive Optical Network (PON) can be tested at three wavelengths of 1310 nm, 1490 nm and 1550 nm recommended by ITU-T (G.983.3).
