MBR1 | Multi-Channel Backreflection Meter

The MBR1 Multi-Channel Backreflection Meter is an instrument developed with extremely stable optics for precise measurement of backreflection, insertion loss, and power. Available with 4, 12, 16, 24, 32, 48 or 72 output channels, the MBR1 is a practical choice for both single fiber and multifiber testing.

The MBR1 features up to four built-in laser sources at wavelengths of 450, 650, 780, 850, 1060 1300, 1310, 1490, 1550, 1625 or 1650 nm (depending on fiber type). Custom configurations available per request.

The MBR1 achieves ultra-stable backreflection measurements at very low values with accuracy typically at ±0.4 dB and measurement sensitivity is to –80dB. In addition, the cavity option is particularly useful for multi-fiber connectors with large fiber counts. The MBR1 can be used with our GMS software to help automate short and long term testing. All our MBR1 meters come standard with our GMS Software at no additional cost. The multimode option of the MBR1 meets IEC 61280-4-1 Encircled Flux standard.
