The Luna OBR 6225 will bring significantly enhanced diagnostic capabilities to the installation and maintenance of commercial and military avionics, data center networks and industrial manufacturing applications. The Luna OBR 6225 is a portable and rugged ultra-high resolution reflectometer with backscatter-level sensitivity for testing short networks deployed in aerospace, naval, data center and industrial applications. Troubleshoot fiber assemblies in the field to easily locate optical loss events with sub-millimeter resolution. The OBR 6200 Series utilizes optical frequency domain reflectometry (OFDR) technology to measure distributed return loss (RL) and insertion loss (IL) with high precision and dynamic range. The OBR 6200 Series easily locates optical loss events with sub-millimeter resolution.
