Test and Inspection OPM5 and OPM4 Optical Power Meters 1 AFL is a trusted supplier of optical testing equipment with more than 30 years of experience and tens of thousands of units in use in the field. AFL’s full range of power meters are used for testing single-mode and/or multimode fiber networks. Power meters with wave ID can detect two or more wavelengths simultaneously – decreasing test time and reducing user errors when paired with AFL wave ID light sources. Designed for the real world: AFL’s power meters are designed to meet the demands of the outside plant environment. They withstand the one-meter drop test and have splash resistant controls that are easy to use, even with gloves on. Flexible and efficient: A range of field-swappable output adapters enables access for cleaning optical ports and supports multiple connector styles. The efficient design provides long test time from globally available AA batteries. Equipped with five-minute auto-off feature to save power. Reduce test time and errors: Wave ID (Dual or Single) decreases test time while reducing technician errors. Stores test results: AFL’s OPM5 stores optical reference at each calibrated wavelength. This enables technicians to organize test results into multiple files and transfer stored results via USB to the included PC-based TRM ® 3.0 software for analyzing, generating reports, and printing. Users can generate network Pass/Fail results demonstrating compliance to industry standards and illustrate headroom. Fully N.I.S.T. traceable.

Full-featured, handheld optical power meter
NOYES OPM4 is designed for measuring optical power in all network types and performing insertion loss measurements on multimode or single-mode fibre optic links. The OPM4 is fully N.I.S.T. traceable.
Automatic Wavelength Identification Significantly Increases Efficiency
The standard Wave ID feature automatically detects and sets the receive wavelength(s), preventing setup and measurement errors (when used with NOYES OLS series light sources). It significantly increases efficiency and reduces technician errors—and saves testing time—by eliminating the need to test each wavelength individually.
Optical References Storage
The OPM4 stores optical references for each calibrated wavelength and offers multiple test tone detection for fibre identification.
