The LWA 7601-C LightWave component Analyzer is a fast and simple-to-use tool for testing passive optical components and modules. The LWA 7601-C measures and analyzes the Insertion Loss (IL) and Return Loss (RL) distribution, as well as length, scanning optical components in either reflection or transmission mode.

The LWA 7601-C instrument utilizes optical frequency domain reflectometry (OFDR) technology to measure backscattered or transmitted light as a function of distance/time (or wavelength). The extremely high sensitivity and sampling resolution (20 μm) make an ideal analyzer for photonic integrated circuits (PICs) and silicon photonics. When combined with the extended measurement range, up to 500 m measurement range is achieved, making the testing of fiber networks an easy task. The LWA 7601-C reduces the cost and complexity of test while increasing throughput by measuring RL, IL and length in reflection or transmission with a single instrument.
