A Correct answer
Explanation

Multi-mode fiber for ISLs (Inter-Switch Links) in Fibre Channel networks typically supports distances up to 500 meters. Multi-mode fiber uses multiple light paths and LED or laser sources, which causes modal dispersion that limits effective distance. For longer ISL distances, single-mode fiber must be used instead. The 500 meter distance is the standard limit for multi-mode in SAN environments.
