Datasheet

Overview

The Luna 6415 is a lightwave component analyzer for testing passive optical components and fiber optic networks. It measures and analyzes the insertion loss (IL) and return loss (RL) distribution, as well as length, scanning the optical component in either reflection or transmission mode.

The instrument uses optical frequency domain reflectometry (OFDR) to measure backscattered or transmitted light as a function of distance. Its high sensitivity and sampling resolution of 20 μm make it suited to photonic integrated circuits (PICs), silicon photonics, passive components and fiber optic assemblies.

By measuring RL, IL and length or delay in reflection or transmission with a single instrument, the Luna 6415 reduces the cost and complexity of test while increasing throughput in production environments. In reflection, standard measurement length modes are 20 m and 50 m, with 100 m and 200 m available through the extended range option OPT06450.

The instrument is controlled from a workstation laptop running the application software and can be operated remotely through SCPI commands over TCP/IP.

The Luna 6415 has been discontinued by the manufacturer; the Lightwave Component Analyzer (LWA 7601-C) is the listed replacement.
