Gigabit Uplink ports - used to connect server and client devices to network switches. In most cases, these ports have more bandwidth than PoE ports.
Their ranges are as follows:

• up to 20km - with fiber-optic connection
• up to 100m - when connected with a UTP cable

PoE+ ports - used to supply power and transmit data to IP cameras using one cable. The total power budget provided by the switch allows you to connect devices with a maximum power consumption from 30W to 38W (support for 802.3at / af protocols)
