While planning to upgrade the infrastructure of an office network to support Power over Ethernet (PoE) alongside data transmission, a technician is considering reusing existing cabling to reduce costs. The PoE devices need to operate on Gigabit Ethernet and require up to 15.4W of power each. Which of the following characteristics should the technician confirm the existent cabling possesses to ensure a successful deployment?
The current cables have RJ11 connectors to ensure telephony-based PoE support on the network.
The installed cables are plenum-rated Cat 5 for optimal fire retardation when deploying the additional electrical power for PoE devices.
The existent Cat 6 cables are equipped with shielded twisted pair (STP) to enable the higher power output required for standardized PoE.
The existing cables are Cat 5e with no signs of physical damage or excessive length that would undermine their signal quality and PoE capabilities.
