Optical Coherence Domain Reflectometer
Discontinued OCDR-1000

Optical Coherence Domain Reflectometer


Replacement Product: Lightwave Component Analyzer

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

Product Description

The OCDR-1000 is based on a polarization optimized white light interferometer. It is a low cost alternative to OFDR technology. The high dynamic range avoids the masking of small reflection peaks 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 to be measured and place the 600mm measurement span in the region of interest. With a reflection dynamic range of over 70 dB and a spatial resolution down to 15 μm, this instrument helps engineers and researchers see the inside of an optical device to precisely identify defects and their locations.
