In optics (particularly in fiber optics) a loss that takes place at discontinuities of refractive index, especially at an air-glass interface such as a fiber endface. At those interfaces, a fraction of the optical signal is reflected back toward the source. This reflection phenomenon is also called "Fresnel reflection loss," or simply "Fresnel loss." Fiber optic transmission systems use lasers to transmit signals over optical fiber, and a high opti… WebOptical Return Loss -An Important Test. When talking about fiber, Optical Return Loss (ORL) is one of the number one things that is tested. This is the ratio of light that is reflected back to the source of the light over the entire fiber link. This is always measured in dB (decibels) and will typically be a negative number.
