LWA 7000 Lightwave Analyzer
LWA 7000 Series

Lightwave Component Analyzer

The LWA 7601-C Lightwave Component Analyzer is a fast and simple-to-use tool for testing modern optical components and modules, including Photonics Integrated Circuits (PICs). The LWA 7601-C measures and analyzes the Insertion Loss (IL) and Return Loss (RL) distribution, frequency response, as well as length.  Optical components are scanned in either reflection or transmission mode.

Product Description

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.
