QuestionQ6

SAN concepts

A company has a Fibre Channel environment and wants to connect a new host in a remote data center with 50/125um OM2 multi-mode fiber cable, while supporting 2 Gb speeds. What is the maximum supported cable-run distance in this scenario?

  • A 50/125um OM2 multi-mode fiber cable supports up to 500 meters at 2 Gb.
  • B 50/125um OM2 multi-mode fiber cable supports up to 10000 meters at 2 Gb.
  • C 50/125um OM2 multi-mode fiber cable supports up to 150 meters at 2 Gb.
  • D 50/125um OM2 multi-mode fiber cable supports up to 300 meters at 2 Gb.
Explanation

At 2.125 Gbps Fibre Channel, shortwave optics support 50/125-µm OM2 multimode fiber for up to 500 meters. Cisco’s Fibre Channel SFP specifications list 500 m for OM2 at that speed.
