What is the typical attenuation value for a fusion splice?

Fusion splicing welds the fiber ends into a seamless joint, so light passes with minimal disruption. In a well-executed fusion splice, the insertion loss is very small—typically around a few hundredths of a decibel. The value about 0.05 dB reflects that level of loss commonly observed for a good splice. Larger losses like 0.3 dB, 0.5 dB, or 1.0 dB would indicate a subpar splice or issues such as dirty end faces, poor alignment, or contamination, not what you’d expect from a properly performed fusion splice. In practice, many technicians aim for 0.1 dB or less per splice.
