Optical Return Loss Measurement
The magnitude of backscatter depends on fiber type, transmitted optical power level, and optical wavelength. The transmission distance will also afect the backscatter level: the longer the fiber
Where does optical return loss matter?
When an optical signal pulse hits an angled (APC) endface, the signal is reflected into the cladding of the fiber rather than back down the fiber core. This allows APC connectors to have low reflectance,
