MBR5 Multi-Output Backreflection Meter


The MBR5 Multi-Output Backreflection Meter is an instrument developed with extremely stable optics for precise measurement of backreflection, insertion loss and power. Available with 4, 12, 24, 48 or 72 (MM) output channels, the MBR5 is a practical choice for both single fiber and ribbon fiber testing.

The MBR5 Multi-Output Backreflection Meter features up to four built-in laser sources at wavelengths of 850, 1310, 1490, 1550, 1625 and 1650 nm (depending on fiber type), and can be configured for single-mode or multimode measurement.

An intuitive display and keypad simplifies the collection and management of measurement data allowing quick access to the test results from various channels. The MBR5 achieves ultra-stable backreflection measurements at very low values. Accuracy is typically ±0.4 dB and measurement sensitivity is to -80 dB. Insertion loss relative accuracy is ±0.05 dB.
