If you don’t know, you could be experiencing channel or network errors and not understand why. The problem may be that you’re exceeding the optical loss budgets of your hardware.
An optical loss budget is the minimum amount of light loss allowable between two connected transceivers. This amount is determined by the standards bodies as well as the manufacturers of the electronics. Optical loss is measured in decibels (dB).
There are a number of important factors about fiber optic cables and light loss to keep in mind. It is important to understand the basics of optical loss budgets and how the cabling you purchase can affect the hardware that it is plugging into.
Many times a hardware speed upgrade leads to errors from cabling that had worked previously, but cannot meet the loss budget of the new hardware.
This is useless information for a budget as the assembly may not be “typical” and have higher loss amounts.
Many fiber assemblies have high dB loss. They may look just like any other assembly, but not perform as well as you need them to.
