Optical loss is measured using an optical time-domain reflectometer (OTDR), which can provide a graphical representation of the fiber optic link's loss and length. Various measurement techniques are used in fiber optic deployments—one of them is the Optical Loss Test Set (OLTS). It calculates the optical signal loss between two points by comparing transmitted and received power levels. But what exactly is being measured, and why is this value so critical for. This is similar to the single-ended loss measurement of terminated cables, but uses the splice instead of connectors at the source end and a bare fiber adapter to connect the fiber to the power meter. Factors causing fiber loss are various, such as intrinsic material absorption, bending, connector loss, etc. Losses in the optical fiber can be categorified. Fiber optic loss, also known as optical attenuation, refers to the reduction of optical signal power as light propagates through an optical fiber link.
