The Noyes OPM 4 OLS 1 OLS 2D is a series of light sources, optical power meters, and related test kits designed for fiber optic testing and inspection. This user's guide provides detailed information on the function, usage, and maintenance of these devices.
Function Description
The OPM (Optical Power Meter) series, including OPM4 and OPM5 models, are used to measure optical power in fiber optic networks. They can display measurements in dBm, dB, or µW. The OPMs are capable of storing measurement data and can be used to set reference levels for loss measurements. They support various wavelengths and can identify wavelengths from ID'd sources.
The OLS (Optical Light Source) series, including OLS1, OLS2, OLS4, OLS7-3, and OLS7-FTTH models, are used to generate stable light signals at specific wavelengths for testing fiber optic links. These light sources are essential for performing insertion loss measurements when paired with an OPM. Some OLS models feature multiple wavelengths and tone generation capabilities.
The overall system, comprising OPMs and OLSs, facilitates the measurement of optical power and insertion loss in both multimode and single-mode fiber optic links. This is crucial for verifying the performance and integrity of fiber optic installations.

Usage Features
- Intuitive Interface: Both OPM and OLS devices feature clear displays and dedicated buttons for easy operation, including power on/off, wavelength selection, mode selection (CW/Tone), and reference setting.
- Wavelength Selection: Users can manually select the desired test wavelength or utilize the OPM's automatic wavelength identification feature when paired with a compatible OLS.
- Reference Setting (One Jumper Method): This method is used to establish a 0 dB reference for insertion loss measurements. It involves connecting the OLS to the OPM via a single test jumper, wrapping the jumper around a mandrel (for multimode), and then setting the reference on the OPM.
- Test Jumper Verification: Before measuring link loss, the integrity of the test jumpers themselves can be verified by connecting them in series and checking the displayed power level. This ensures that the jumpers do not introduce excessive loss into the measurement.
- Insertion Loss Measurement: After setting the reference and verifying jumpers, the OLS and OPM are connected to the fiber link under test (via a patch panel), and the OPM displays the insertion loss in dB.
- Data Storage (OPM5): The OPM5 allows users to save measurements to internal memory, which can then be retrieved, viewed, or cleared.
- File Management (OPM5): The OPM5 offers file management features to select, create, and manage files for storing measurement data, facilitating organized record-keeping.
- Display Readings: Both OPMs and OLSs provide clear display readings of current measurements, battery status, and selected settings. OPMs can display splash screens for software version and detector type.
- Output Adjust (Laser Sources): OLS2, OLS7-3, and OLS7-FTTH models allow users to adjust the optical output power, providing flexibility for various testing scenarios.
- Tone Generation (Laser Sources): OLS2, OLS7-3, OLS7-FTTH, and OLS4 (for laser output) can generate modulated light signals at specific frequencies (tones), which can be useful for fiber identification or troubleshooting.
