(calculate to preview)

Typical α (attenuation): OS2 0.35 dB/km @1310, 0.22 @1550; OM3 3.5 @850, 1.5 @1300; OM4 3.0 @850, 1.5 @1300. Loss = α·L + (conn × loss) + (splice × loss) + (splitter × loss) + cleanliness + margin. Advisory only; confirm with vendor specs and test results (OTDR/OLTS).

Preliminary Estimate Only: Validate against transceiver datasheets. Clean and inspect connectors; test with OLTS/OTDR. Include patching path losses if intermediate panels are used.
