The Noyes OPM5-4D from AFL Telecommunications is a full-featured, handheld optical power meter designed for measuring optical power in Premises, Telco, or Broadband networks and for performing insertion loss measurements on multimode or single-mode fiber optic links. The OPM5-4D features automatic wavelength identification and switching (Wave ID) when used with Noyes OLS series light sources, multiple test Tone detection for fiber identification, and stores optical references for each calibrated wavelength and up to 500 records per wavelength of power or insertion loss measurements. A large dual-wavelength LCD display with backlight shows measured power [dBm or µW] or insertion loss [dB], calibrated wavelengths [nm], tone signal [Hz], wavelength ID, and estimated remaining battery life. Specifications. Calibrated wavelengths: 850, 980, 1310, 1490, 1550, 1625 nm. Detector type: Filtered InGaAs. Measurement range: +26 to -50 dBm. Tone detect range: +6 to -30 dBm, +6 to -25 dBm for 850nm. Wavelength ID range: +6 to -30 dBm, +6 to -25 dBm for 850 nm. Accuracy: ± 0.25 dB. Resolution: 0.01 dB. Measurement units: dB, dBm, µW.
