A technician is tasked with installing cabling for a new Gigabit Ethernet network that will support Power over Ethernet (PoE) in a small office environment. Which of the following types of unshielded twisted pair cable is most suitable for this application while keeping costs low?
Cat 5e cable is the correct choice because it supports Gigabit Ethernet speeds (1000 Mbps) and is capable of handling Power over Ethernet functionalities correctly. Cat 5 does not officially support Gigabit Ethernet and Cat 3 is designed for much lower speed networks (10 Mbps), so neither would the network performance requirement. Cat 6 goes beyond the necessary specifications for Gigabit Ethernet and PoE, but for a small office setup, the cost versus benefit ratio might not justify the increased expense and potential installation challenges with respect to its more rigid structure.
