OZ Optics backreflection meters feature a SLED source

Benchtop backreflection meters feature a broadband superluminescent light-emitting diode (SLED) source for greater stability and sensitivity, and an optional second photodetector for insertion loss measurement. It can cover telecommunication wavelengths as well as 1060, 830, and 650 nm wavelengths, and works with single-mode, polarization-maintaining, and multimode fibers.
