LWA 7000 Series Lightwave Component Analyser

The Luna LWA 7601-C Lightwave Component Analyser is an advanced, fast, and user-friendly tool designed for testing passive optical components and modules with remarkable efficiency. This sophisticated instrument measures and analyses critical parameters such as Insertion Loss (IL) and Return Loss (RL) distribution, as well as determining the length of optical components. It offers the flexibility to scan these components in either reflection mode or transmission mode, depending on the testing requirements.

This specialised instrument uses cutting-edge optical frequency domain reflectometry (OFDR) technology, allowing it to measure backscattered or transmitted light based on distance/time (or wavelength). With extremely high sensitivity and an impressive sampling resolution of 20 μm, the LWA 7601-C is ideal for analysing photonic integrated circuits (PICs) and silicon photonics applications. Its extended measurement range, reaching up to 500 meters, simplifies testing procedures for fibre networks, making it a valuable asset in the field.

Additionally, the LWA 7601-C reduces costs and complexity associated with optical testing while enhancing throughput by measuring RL, IL, and length in both reflection and transmission modes—all with a single, versatile instrument. This combination of features makes the Luna LWA 7601-C an indispensable tool for professionals working with optical components and systems, ensuring accurate and efficient testing across various applications.

Measuring in reflection mode, the LWA 7601-C measures return loss versus length. The bottom plot shows the spectral content of the identified reflection event (filter).
