The all-optical network, combined with optical reflectors, can automatically locate fiber breaks and fault points, with a fault location accuracy of within 10 meters.

• BFalse

• A

• B
  26% (11)

Explanation

Option A is correct because all-optical networks, when combined with Optical Time-Domain Reflectometry (OTDR) technology, can precisely detect fiber breaks and fault points by measuring the time it takes for reflected light pulses to return - achieving fault location accuracy within 10 meters or better. This technique works by sending short light pulses into the fiber and analyzing backscattered or reflected signals to pinpoint discontinuities. Since B claims this statement is false, it is incorrect - OTDR-based fault location in optical networks is a well-established, proven capability in telecommunications infrastructure.

Memory tip: Think of OTDR as "optical sonar" - just as sonar uses reflected sound waves to locate objects underwater with high precision, OTDR uses reflected light pulses to locate faults in fiber with meter-level accuracy. If you remember "light travels fast, but timing is precise," you'll recall why optical fault detection can be so accurate.
