A technician needs to connect two buildings 800 meters apart with high bandwidth and immunity to electromagnetic interference. Which medium is best?
a.Cat 6 UTP
b.Coaxial cable
c.Cat 5e UTP
d.Single-mode fiber
解析
Single-mode fiber supports long distances well beyond copper's 100-meter limit and is immune to electromagnetic interference. Twisted-pair copper cannot reach 800 meters. Fiber is the standard choice for building-to-building backbone links.
