LM series optical multimeter with integrated power meter, laser source, and optional VFL for fiber power, loss, continuity, and fault testing.
The LM Series Optical Multimeter is a versatile and compact solution that integrates an optical power meter, laser source, and optional visual fault locator into a single device. Designed for field technicians and lab engineers, it provides the essential tools to test optical power, measure loss, verify continuity, and detect faults in fiber optic systems.
Featuring auto-wavelength recognition and tone detection, the LM series simplifies operation by automatically identifying key wavelengths and modulation tones. Its backlit display and auto power-off function enhance usability in different environments, while its compact and lightweight design ensures easy portability for field work.
The optical power meter offers high accuracy with a measuring range tailored to various models, while the laser source delivers stable output at key telecom wavelengths (1310/1490/1550 nm) with selectable modulation frequencies. The optional built-in visual fault locator enables quick fault pinpointing without the need for additional equipment.
With robust construction, interchangeable connectors, and the ability to operate in a wide temperature range, the LM Series Optical Multimeter is the ideal all-in-one test instrument for installation, maintenance, and troubleshooting of fiber optic networks.
