The portable OBR 4200 optical backscatter reflectometer from Luna Technologies offers inspection and diagnostic capabilities to manufacturers and installers of fiber-optic assemblies and short networks. According to Luna, the OBR 4200 delivers a resolution that is 1000 times that of an OTDR.
The OBR 4200 allows you to "see" any event in a fiber assembly or network out to 500 m with no dead zone. Luna says it provides a spatial resolution of less than 3 mm, Rayleigh-level sensitivity down to –120 dB over the entire measurement range, and insertion loss resolution of 0.1 dB with the ability to identify nonreflective failures. In addition, the OBR 4200 has an operational wavelength of 1540 nm and offers both single-mode output (standard) and multimode output (optional).
You can use the OBR 4200 to verify the quality of optical-fiber cable assemblies, connectors, and short-run networks; troubleshoot and distinguish between macro-bends, splices, connectors, and breaks; locate insertion loss points; and verify return loss of multiple points in a fiber assembly or harness simultaneously.
