You perform a Tier 1 certification (OLTS) on a multi-mode fiber link. The measured loss is 2.5 dB, but the calculated loss budget is 1.8 dB. What is the immediate result?
Answers
AThe link passes because 2.5 dB is less than 3.0 dB
BThe link fails certification and requires troubleshooting or re-termination
CThe link conditionally passes but requires an OTDR trace
DThe link passes because multi-mode allows up to 5 dB of loss
Correct answer: B — The link fails certification and requires troubleshooting or re-termination
If the measured insertion loss exceeds the calculated loss budget for that specific link (based on length, splices, and connectors), the link fails certification.
