Overview

The Luna OCDR-1000 is an optical coherence domain reflectometer designed to obtain space-resolved reflection information inside a fiber optic component, such as a Photonic Integrated Circuit (PIC), in order to diagnose quality or design issues.

The instrument is based on a polarization-optimized white light interferometer and was positioned as a lower-cost alternative to OFDR technology. Its high dynamic range prevents small reflection peaks from being masked by the large reflections typical of the input surface of an optical device.

A set of length-matching delay modules is available to match the pigtail lengths of the devices under test and place the 600 mm measurement span in the region of interest. With a reflection dynamic range of over 70 dB and fine spatial resolution, the OCDR-1000 lets engineers and researchers locate defects inside an optical device.

The OCDR-1000 has been discontinued by the manufacturer. Luna lists the Lightwave Component Analyzer (Luna 6400 Series) as its replacement.
