Optical Power Meter Ultimode OPM-20T-V01, model OPM-20T-V01

The Ultimode OPM-20T-V01 is a handheld optical power meter designed for measuring optical signal power in fiber networks. This portable instrument provides direct power readings to support testing and maintenance of fiber links and active equipment. Built for field use, the device is suitable for installers and technicians who need quick verification of signal levels, routine checks, and troubleshooting of fiber-optic systems.

Advantages

The meter offers straightforward, single-handed operation and a compact housing that fits into a service bag or toolbox. Its measurement range and responsive detector allow accurate readings of optical power across common fiber wavelengths. The device is battery-powered for field portability and provides stable readings suitable for rapid verification tasks. The design emphasizes durability and ease of use for repeated site visits and live network checks.

Suitable for

• Verification of signal levels on singlemode fiber links
• Routine maintenance and periodic fiber network checks
• Field troubleshooting and fault isolation in optical links
• Installation testing and acceptance checks for fiber equipment

Key specifications

• Form factor: handheld, portable
• Optical interface: industry-standard fiber connector adapter compatible with singlemode fibers
• Measurement type: absolute optical power readings
• Power measurement range: suitable for common field-level optical powers (device provides negative and positive dBm readings as required by application)
• Wavelength support: measures power at standard telecommunication wavelengths used in fiber networks
• Power source: battery operation for field use
• Display: clear numeric readout for quick interpretation of measured power

How to use

Power on the meter and allow the detector to stabilize if required. Select or confirm the operating wavelength appropriate for the fiber system under test, then connect the fiber under test to the instrument using the correct adapter to ensure physical and optical compatibility. Read the displayed optical power value and compare it to expected levels for the link or device being tested. When finished, power off the instrument and store it in a protective case or pouch to prevent contamination of the connector and damage to the detector.

Usage recommendations

Before measuring, clean fiber endfaces and adapters to avoid inaccurate readings. Use the correct connector adapter for the fiber type and wavelength, and allow the meter to warm up if the manufacturer specifies a stabilization time. Regularly check battery condition and replace batteries to ensure reliable field operation.
