Understanding Optical Loss in Fiber Networks
Insertion loss and return loss can impact fiber network performance - this post explains what they are and gives five tips to reduce their impact.

Fiber optic cable acceptable loss refers to the maximum amount of signal attenuation that can occur in a fiber optic communication system while still maintaining effective performance. 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. Contractors often install, terminate, and certify cabling without knowing the client's specific requirements.
