JDS Uniphase RM3

The JDS Uniphase RM3 is a portable backreflection meter for direct measurement of optical component and system performance. It analyzes backreflection, insertion loss, and optical power across a wide wavelength range, supporting both single-mode and multimode fiber configurations. The instrument delivers -75 dB backreflection sensitivity and power measurement down to -80 dBm, making it essential for optical communications, research, and manufacturing environments where precise spectral characterization of connectors, components, and systems is required.
