The LB5500 is a high-performance bench-top loss test station specifically designed for optical passive components production testing and laboratory applications. It combines three essential functions — return loss meter, optical power and loss meter, and stable laser source — into a single, compact instrument, streamlining testing workflows for maximum efficiency.
This test station delivers high measurement accuracy with a wide dynamic range, ensuring reliable results even with weak optical signals. The integrated design of the Optical Power Meter (OPM) and Optical Light Source (OLS) modules reduces operation steps, while the removable optical connector set allows easy cleaning and maintenance. A backlight-adjustable display ensures optimal visibility in various lighting conditions, and the USB interface enables fast data transfer to a PC for analysis and reporting.
Compatible with both single-mode (SM) and multi-mode (MM) fiber testing, the LB5500 supports multiple calibrated wavelengths and interchangeable connector adaptors, making it highly versatile for different fiber optic systems. Its robust construction, compact footprint, and user-friendly software make it an indispensable tool for professional optical testing environments.
