Optical OFDM Error Floor Estimation by Means of OTDR Enhanced by Front-End Optical Preamplifier
Optical time-domain reflectometer (OTDR) enables simple identification and localization of a plethora of refractive and reflective events on a fiber link, including splices, connectors and breaks, and measuring insertion/return loss. Specifically, large enough OTDR dynamic range (DR) and thus high s...
