How Fiber Optic Attenuation Is Tested During Production — And Why It Matters

Attenuation (signal loss) is one of the most important performance indicators of a fiber optic cable.
Whether the cable is used for FTTH, outdoor backbone, ADSS, OPGW, or data center projects, stable attenuation ensures stable network performance.

Today’s article explains how attenuation is tested during production and why every cable must pass 100% testing before shipment.
