  • How to measure optical cable return loss

    How to measure optical cable return loss

    Optical return loss is the amount of light that is reflected back to the source, this reflected light is measured at each connector and splice at each point over the entire fiber link. It is also called. Beginning with software release 1. Optical return loss for individual events, i. As shown in the figures above, the OCWR Testing setup for reflectance or return loss tests of connectors or passive fiber components per industry standards (TIA FOTP-107 or IEC 61300-3-6) using a light source. To ensure the proper performance of an optical transmission system, various parameters—such as attenuation and optical return loss (ORL)—must be within the acceptable tolerance levels of both the transmission and receiving equipment. VIAVI Time Domain IL/ORL Meter ORL is the ratio between the light launched into a device and the light reflected.
