You are shooting an OTDR trace on a short 100m patch cord but cannot see the connector at the far end clearly due to the initial pulse width. What setting should you adjust?
Answers
AChange the wavelength from 1310nm to 1550nm
BIncrease the pulse width to push more power into the fiber
CDecrease the pulse width to improve spatial resolution
DIncrease the averaging time to 3 minutes
Correct answer: C — Decrease the pulse width to improve spatial resolution
A shorter pulse width provides better spatial resolution, allowing the OTDR to distinguish closely spaced events, which is essential for short links.
