This port uses a 10/100/1000 Ethernet connection with an RJ-45 interface. Connect the RJ-45, UTP cable to the MGMT ETH port on the switch. >>>Read More:What is the difference between SFP+ high speed cableSFP+ electrical port moduleSFP+ optical module Ethernet ports on switches already integrate Ethernet port modules internally, eliminating the need. Most gigabit switches are equipped with both RJ45 electrical ports and SFP optical ports. To configure a particular speed, mention the speed. An all-optical Ethernet switch is a network switch whose service ports are entirely optical, meaning every interface uses fiber rather than copper. This design enables end-to-end optical signal transmission, avoiding the conversion between electrical and optical signals at the switch port level. The cable is almost 20 meters long.
