Detailed explanation-1: -PoE technology sends 10/100/1000 Mbps of data and 15W, 30W, 60W, and up to 90W of power budget to devices over Cat5e, Cat6, Cat6a. Cat7 and Cat8 Ethernet cables for a maximum distance of 100m.
Detailed explanation-2: -Power over Ethernet is injected onto the cable at a voltage between 44 and 57 volts DC, and typically 48 volts is used.
Detailed explanation-3: -Ethernet-Sending One Packet Here’s an oversimplification that captures how it works: the ethernet cable contains two wires connecting the computers. The sending computer could read through the 12000 bits in order, and for each 1 bit, put 3 volts between the wires, and for each 0 bit, put 0 volts between the wires.
Detailed explanation-4: -UNIVERSAL VOLTAGE POWER PACK W/RJ45 CONNECTION 120/230/277 VOLTS.
Detailed explanation-5: -Ethernet transmits data packets in this data link layer by using an algorithm called CSMA/CD (Carrier Sense Multiple Access with Collision Detection). CSMA/CD is used as a standard for Ethernet to reduce data collisions and increase successful data transmission.
