Abstract
This article discusses 3 methods for measuring of optic return loss (ORL) in fiber optic systems being used in modern measuring instruments: continuous wave method (CW), time domain reflectometry (OTDR) and frequency domain reflectometry (OFDR). The authors perform a comparative analysis of these methods, and consider the advantages and limitations of these methods.
