A facilities are two office buildings 400 feet apart, each with its own LAN.

To connect the two networks, you plan to dig a trench and lay cable in conduit between the two buildings.

you want to use fiber-optic cable, but your budget-conscious facilities manager wants to use 100 Mbps Ethernet over twisted-pair. Which of the following reasons can you use to justify fiber-optic cable in this case, and why?

Twisted pair wont span a 400-foot distance.

Fiber-optic cable is cheaper and easier to work with than twisted pair

Twisted pair is a conductive cable and can, therefore, carry current based on the difference in ground potential between the two buildings.

Fiber-optic cable leaves more room for growth and future needs for increased bandwidth than twisted pair does
