Under a fiber microscope, you observe permanent pitting and scratches crossing the 9-micron core of a single-mode LC connector, even after multiple wet/dry cleanings. What is the impact on performance?
Answers
AIt will only affect transmission if using 1550nm
BIt will cause high insertion loss and poor reflectance (low ORL)
CIt has no effect as long as the cladding is intact
DIt will cause the fiber to melt when used with high power lasers
Correct answer: B — It will cause high insertion loss and poor reflectance (low ORL)
Scratches and pitting across the core permanently degrade the optical signal by scattering light, increasing insertion loss and causing high back-reflection.
