For normal fiber broadband, the ideal range of light attenuation is -20dBm to -25dBm. With light attenuation at -27dBm, speeds are limited to a maximum of 100M, and with light attenuation at -28dBm, speeds are limited to a. Fiber loss, or attenuation, refers to the reduction in optical power as light travels through a fiber optic cable. While some loss is expected, excessive or unexpected loss can lead to poor performance, network downtime, and signal failure. Recognizing what constitutes too much loss is essential. 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. Attenuation refers to the loss of light as it travels down the fiber. This can be due to a variety of factors: scattering and absorption, intrinsic loss, extrinsic loss, bending losses and more.
