Why is attenuation necessary in optical fiber cables

Attenuation makes signals weaker in fiber optic cables. Check your optical transceiver's specs often. It's measured in decibels per kilometer (dB/km), and it determines how far a signal can travel before it becomes too weak to read. A standard single-mode fiber operating at 1550 nm loses. Optical Signal Attenuation is the single greatest factor limiting the distance and performance of your network. This can be due to a variety of factors: scattering and absorption, intrinsic loss, extrinsic loss, bending losses and more.
