Standards for Fiber Loss

Telecommunications Industry Association (TIA)/Electronic Industries Alliance (EIA) develops TIA/EIA standards, which specify performance and transmission requirements for fiber optic cables, connectors, etc. and are widely accepted and used in the optical fiber industry. The maximum attenuation is actually the attenuation coefficient of fiber optic cable, which is expressed in dB/km units. It is one of the most important parameters for fiber loss measurement. According to TIA/EIA-568, the maximum attenuation for different types of fiber optic cables are shown in the following graph:
