BR5 Series
Single Output Backreflection Meter
The BR5 Backreflection Meter is a user-friendly instrument developed with extremely stable
optics for precise measurement of backreflection, insertion loss and power. The BR5 features
up to four built-in laser sources at wavelengths of 850, 1310, 1490, 1550 and 1625 nm
(depending on fiber type).
An intuitive display and keypad, with one-button access to BR and IL modes, simplifies the
collection and management of measurement data. Available in single-mode and multimode,
the BR5 is ideal for measurements of connectors, components and systems.
The BR5 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.
MBR5 Series
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, or 48 output channels, the MBR5 is a practical choice for both single fiber and
ribbon fiber testing. The MBR5 features up to four built-in laser sources at wavelengths of 850,
1310, 1490, 1550 and 1625 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. In
addition, the 10 mm Ge detector option is particularly useful for ribbon connectors with large
fiber counts.
Backreflection Range 0 to -60 dB Multimode / 0 to -80 dB Single Mode
