Why is the Poe switch the cheapest and most convenient choice for the village network solution?

POE (power over Ethernet) refers to providing data transmission signals for switches, routes, and APS in the existing Ethernet structure without changing the structure, it can also provide DC power supply technology for such devices.

Poe has always been an expensive option, but this problem has recently changed with the emergence of simple Poe switches.

The following describes how to analyze the cost of three power supply solutions for broadband rental by configuring 16 completely new switches with a network of M nodes:

A. Power supply from the landlord where the switch is located. An electric meter must be installed, and an open-air switch or an electrical outlet must be installed.

1. electric meter (25 yuan, 15 yuan electric meter is not available at all, you use 10 degrees of electricity, he runs 30 degrees directly, use this electric meter to lose more)

2. Air Switch (5a, 8 RMB)

3. socket (3 RMB)

4. Plug (2 RMB)

5. Wire (20 yuan, with 1.0 copper wire, 1 yuan/meter)

6. 150 RMB for 16 new Switches

Total Solution amount: 58 + 150 = 208 yuan

B. cables and power cables are used together. The main devices are wires and sockets, and there are plugs.

1. socket (3 RMB)

2. Plug (2 RMB)

3. Wire (100 meters, with 1.0 copper wires, 1 RMB/meter)

4. 150 yuan for 16 new Switches

Total Solution amount: 105 + 150 = 205 yuan

C. Power Supply for the Poe solution. The main device is the Poe switch.

1. 16 new Poe switches (180 RMB)

Wires go through the network, without the need for sockets, plugs, electric meters, wires, and open air. There is almost no cost.

Total Solution amount: 180 yuan

It is not difficult to see from the data above:

Poe is the best solution to win the Village Network with the advantages of lowest cost, convenient maintenance and high security. From now on, you do not need to take power again. When the network cable is connected, there will be power wherever it is. This will not only save costs, but also save time for power extraction, the most important thing is that you do not need to take V to run on the street, making it safer.
