BR5 | 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, 1300, 1310, 1490, 1550, 1625 or 1650 nm (depending on fiber type).

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.

JGR's well known BR5 meter is capable of ultra-stable Insertion Loss and Backreflection measurements. With a Backreflection measurement accuracy of ±0.4 dB and an Insertion Loss accuracy of ± 0.05dB, the BR5 is the perfect tool for reliable & accurate measurements. The BR5 can be used with our free easy to use GMS software to help automate test configurations, data logging, and report generation for both short and long term testing needs. The multimode version of the BR5 complies with the encircled flux launch conditions outlined in IEC 61280-4-1 and TIA/EIA 526-14-B.
