## Summary description

Signal OPM-20T-V01 (ULTIMODE) is a handheld optical power meter for testing fiber-optic links. It provides calibrated optical power measurements for single-mode fibers, supports standard wavelengths used in telecom testing, and displays results for quick verification of link loss and signal levels. Suitable for field technicians and lab diagnostics.

## Long description

The Signal OPM-20T-V01 (ULTIMODE) is a handheld optical power meter designed for testing single-mode fiber-optic links. It provides calibrated optical power measurements at standard telecom wavelengths and displays results for quick verification of signal levels and link loss. The compact form factor and clear readout make it suitable for field technicians performing installation, maintenance, and diagnostics of fiber networks.
Advantages
The device offers calibrated measurement capability across commonly used wavelengths, delivering reliable and repeatable readings for verification and documentation of fiber links. Its handheld design and user-friendly interface enable fast on-site testing. The meter’s measurement stability and compatibility with single-mode fiber connectors streamline routine checks and troubleshooting tasks.
Suitable for
 On-site installation and acceptance testing of single-mode fiber links
 Maintenance and troubleshooting of telecom and data network fiber cabling
 Laboratory diagnostics where calibrated optical power readings are required
 Field technicians who need a portable tool for verifying link loss and signal levels
When it may not be suitable
This optical power meter is focused on single-mode fiber measurements and standard telecom wavelengths; it may not be suitable for testing multimode fibers or non-standard wavelength ranges. For applications requiring built-in light sources, automated reporting, or advanced OTDR functionality, a more feature-rich instrument would be more appropriate.
Key specifications
 Handheld form factor with portable weight and size suitable for field work
 Calibrated optical power measurement for single-mode fiber
 Support for standard telecom wavelengths commonly used in fiber testing
 Digital display for immediate readout of power levels and loss indications
 Battery-powered operation for on-site portability
How to use
Connect the optical fiber under test to the meter’s input following proper connector cleaning and handling procedures. Power on the unit and select the appropriate wavelength for the measurement. Allow the meter to stabilize, then read the displayed optical power or loss value. Record readings as needed for documentation. Turn off the instrument after use and store it in a protective case to prevent contamination or damage to connectors.
What to consider before purchase
 Ensure the meter’s supported wavelength range matches the wavelengths used in your network
 Confirm compatibility with the fiber type and connector interfaces you commonly use
 Consider required measurement accuracy and calibration needs for your applications
 Check battery life and whether spare batteries or rechargeable options are needed
Usage recommendations
For reliable measurements, always clean connectors before testing, allow the meter to warm up if specified by the manufacturer, and use a consistent reference method when comparing link loss or power levels across multiple tests.
