WebReturn loss modules. Return loss modules use two power sensors and fiber couplers to provide a direct measurement of the optical return loss. One sensor measures the optical power reflected back to the instrument while the other monitors the optical power output from the instrument. The ratio provides the 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).
