The JDS Uniphase RM2050B is a dual-wavelength backreflection meter engineered for precise measurement of optical fiber component reflection characteristics in single-mode networks. Operating at 1310 nm and 1550 nm, the instrument quantifies backreflection across a 0 to -70 dB range while simultaneously providing optical power measurement capabilities from 0 to -70 dBm. This makes it essential for signal integrity verification and component validation in fiber optic systems.
Technical Specifications
• Operating Wavelengths: 1310 nm and 1550 nm
• Backreflection Measurement Range: 0 to -70 dB
• Optical Power Range: 0 to -70 dBm
• Fiber Type: Single-mode 9/125 µm

– Key Features
• Requires external light source for operation. An unterminated FC/APC output connector baseline of -65 dB reflection serves as measurement reference.
• Verified power meter accuracy within -0.15 dB relative to HP81525A optical head at 1550 nm (-2.73 dBm reference).
• Accommodates lower backreflection measurement with reduced accuracy; -60 dB to -75 dB readings require user calibration and application variance accounting.
• Compatible with 9 VDC external power supply.
• RS-232 interface enables remote control and automated data logging.
– Compatibility & Integration
Designed exclusively for single-mode 9/125 µm fiber. FC/PC source connector and FC/APC output connector configuration requires appropriate adapters for certain measurement scenarios—such as the JDS universal 2.5 mm AC116 for optical power testing—which are not supplied with the instrument. Serial communication via RS-232 allows integration into automated test systems and remote monitoring configurations.
