How to calculate the natural loss during optical cable laying
Fiber optic loss calculation formula: Total link loss (LL) = Cable attenuation + Connector attenuation + Fusion attenuation [Note: If there are other components (such as attenuators), their attenuation values can be added]. To ensure a fiber optic link operates correctly, you need to calculate its loss, power budget, and power margin. The calculation methods are as follows. First, you should be aware of the fiber loss formula: The Total Link Loss = Cable. 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.
