Optical return loss

WebOverview Optical Return Loss (ORL) is the ratio between the light launched into a device and the light reflected by a defined length or region. ORL can be measured using two measurement techniques: optical continuous wave reflectometry (OCWR) or optical time domain reflectometry (OTDR). Both techniques are described in IEC 61300-3-6. WebFeb 26, 2002 · The 12dB return loss for the transmitter is as Ron said a specification on the transmitter, not the cable plant.
