Dual-wavelength optical power meters can display two wavelengths simultaneously, allowing faster and more accurate fiber testing.
Dual-wavelength meters use either optical splitting or electronic separation to measure two wavelengths at the same time. One common method uses a wavelength-division multiplexer (WDM) or thin-film filters to direct light at 1310 nm and 1550 nm to separate detectors, each with its own calibration. Another approach uses a single broadband detector with modulated light sources at different frequencies (e.g., 270 Hz for 1310 nm, 330 Hz for 1550 nm), allowing the meter to electronically separate and display both readings simultaneously. This setup saves time during acceptance testing and ensures accurate detection of wavelength-dependent losses and bend sensitivity in fibers .
AFL OPM5 and OPM4: These meters support Wave ID, detecting two or more wavelengths simultaneously. They are rugged, field-ready, and compatible with AFL dual-wavelength light sources. The OPM5 stores optical references for each wavelength and allows USB transfer to PC software for reporting and analysis .
