Backreflection Meter

The OZ Optics Limited BM-100 and BM-200 Backreflection Meters measure the total accumulated optical return loss that is reflected back through a device or fiber under test. The measured reflections are caused by Rayleigh scattering, sudden changes in the refractive index within the device under test (DUT), or from connector ends. The Backreflection Meter is configured with an FC/APC connector on the output port, to minimize unwanted reflections. The meter has either one or two built-in laser diodes for return loss measurement at specific wavelengths. An optional detector can be added to the unit for insertion loss measurements. Reference patchcords for calibration are available. Adaptor patchcords are also available, to allow the meter to be used with devices having different connectors. The BM-100 and BM-200 Backreflection Meters can be operated remotely via the built-in USB interface. A universal AC/DC power supply is included with all units.
