The BRM Backreflection Meter is an instrument developed with extremely stable optics for precise measurement of backreflection, insertion loss, and power.

Available with 1, 4, 12, 16, 24, 32, 48, or 72 output channels, the BRM is a practical choice for both single fiber and multifiber testing.

The BRM features up to four built-in sources at wavelengths of 450, 650, 780, 850, 1060, 1300, 1310, 1490, 1550, 1625 or 1650 nm. Custom configurations available upon request.

The BRM boasts the best backreflection accuracy in its class (± 0.4 dB) with a measurement sensitivity to -85 dB.

Choose the integrating sphere detector option for multifiber assemblies such as MPO or duplex LC. You can use the BRM with our free GMS software for automated testing.

The multimode BRM is internally conditioned to meet the IEC 61280-4-1 Encircled Flux standard.
