Description
The LM-3 Series Optical Multimeter is a high-performance, rugged testing instrument that integrates an Optical Light Source (OLS), Optical Power Meter (OPM), and Visual Fault Locator (VFL) into a single, portable unit. Designed for installation, maintenance, and troubleshooting of fiber optic networks, it offers technicians a complete solution for measuring optical power, loss, continuity, and pinpointing faults.
With auto-wavelength recognition, modulation frequency detection, and the ability to store up to 1000 test results, the LM-3 series streamlines workflow and improves efficiency. Its LCD display with backlight ensures clear visibility in all lighting conditions, and the USB port allows seamless data transfer for reporting and analysis.
The integrated laser source provides stable output across multiple wavelengths, including 1310/1490/1550 nm, while the built-in 10 mW Visual Fault Locator enables quick location of breaks or defects in fiber. Interchangeable connectors and a wide operating temperature range make it adaptable to various field conditions.
Compact, durable, and equipped with advanced measurement accuracy of ±0.2 dB, the LM-3 Series Optical Multimeter is the ideal all-in-one tool for both field and laboratory applications in fiber optic testing.
