To be able to judge whether a fiber optic cable plant is good, one does a insertion loss test with a light source and power meter and compares that to an estimate of what is a reasonable loss for that cable plant. The estimate, called a "loss budget" is calculated using typical component losses for. This article will teach you how to calculate the loss in the fiber optic link and how to judge the performance of the fiber optic link. Types of Fiber Optic Loss Fiber optic loss, also known as optical attenuation, refers to the light loss between the transmitter and receiver. Factors causing fiber loss are various, such as intrinsic material absorption, bending, connector loss, etc. With loss budgets for 40 and 100 gig applications about half of what they were for 10 gig, every 0.
