WebFeb 26, 2002 · The 12dB return loss for the transmitter is as Ron said a specification on the transmitter, not the cable plant. It is measured by injecting an optical signal into the Tx and measuring how much light is reflected back. It was included to keep Interferometric noise to a … 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.

WebMeasuring insertion loss (IL), optical return loss (ORL) and fiber length calls for an optical loss test set (OLTS). That’s a given, especially for high-count fiber-optic cables considering the greater speed and accuracy of the OLTS over the power meter and light source combo. However, even when using an OLTS the process of re-testing failing ...
