Consideration on the use of OTDRs to measure return loss of single-mode optical fibre connectionsWhat is PD CLC TR 50682 Consideration on the use of OTDRs to measure return loss of single mode optical fibre connections about? PD CLC TR 50682 discusses consideration on the use of OTDRs. OTDR is a device that tests the integrity of a fiber cable and is used for the building, certifying, maintaining, and troubleshooting fiber optic systems.
