What is the average attenuation for a mechanical splice?

When two fiber ends are joined with a mechanical splice, the signal loss comes from the imperfect alignment and any tiny gap between the fibers. A well-made mechanical splice typically introduces a modest amount of loss, but not as much as older, less precise methods. The common average insertion loss for a high-quality mechanical splice is about 0.10 dB, which sits between the very low losses of fusion splicing and the higher losses you can see in poorer alignments. Numbers like 0.01 dB would imply near-perfect alignment that isn’t achievable in practice, while 0.30 or 0.50 dB reflect worst-case or older equipment rather than the typical average. So, 0.10 dB best matches the typical average for a mechanical splice.
