XGSPON-VO-503 Optical Power Meter is a power meter for measuring the power of GP0N/EP0N and XGP0N/XG-SP0N network uplink and downlink signals, including 1270/1310nm uplink signals and 1490/1550/1577nm downlink signals. Integrating 5 functions, VFL, RJ45 LAN cable test,auto Wavelength recognitionand switching. Test stimualated downstream XGSPON and GPONand stimualated show it on screen, It can simultaneously test and evaluate the optical power value of voice, data and video signals. It can measure all P0N signals and measure each wavelength separately. With "Pass/Fail" threshold level authentication detection function by setting different thresholds corresponding to different wavelengths, ensuring that service providers can improve system performance by verifying network connectivity.
