BR5 的特点是内置了若干个波长分别为 850，1310，1490，1550，1625 和1650nm（根据光纤类型有所不同）的激光源。直观的屏显和键盘以及 BR 和 IL 模式之间的一键切换，简化了测试数据的收集和管理。
BR5可在低损耗的前提下完成极其稳定的后向回波反。精度主要在 0.4dB，而测试灵敏度达到 -80dB 插入损耗的相对精度为 0.05dB.
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.
