Why Splice Quality Matters
Every splice in the path is something the light has to pass through. A dirty or poorly aligned splice scatters and absorbs photons — that loss adds up across an entire link and shows up as low signal at the ONT or test set.

Attenuation
Each splice consumes part of your power budget. Three sloppy 0.3 dB splices = nearly 1 dB gone before the signal ever leaves the cabinet.
Reliability
Bad splices fail later — usually in winter, at 2 a.m., on someone else's truck. Clean splices stay clean for decades.
Truck Rolls
Every callback costs the company money and costs you time. The splice you take an extra minute on today is the splice you don't drive back to next month.
