The MBR5 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, 24, 48 or 72, output channels, the MBR5 is a practical choice for both single fiber and multi fiber testing.
The MBR5 features up to four built-in laser sources at wavelengths of 850, 1300, 1310, 1490, 1550, 1625 and 1650 nm (depending on fiber type), and can be configured for single-mode or multimode measurements.
An intuitive display and keypad simplifies the collection and management of measurement data allowing quick access to the test results from various channels. The meter may be controlled through remote interface (GPIB, RS232, or USB*) or locally via the user-friendly front panel keypad and display.
The MBR5 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 MBR5 can be used with our GMS software to help automate short and long term testing. All our MBR5 meters come standard with our GMS Software at no additional cost. The multimode option of the MBR5 meets IEC-61280-4-1 Encircled Flux Standard.
