Application:
Using this set of POE power supply cables can solve the problem of power supply for indoor and outdoor equipment that is inconvenient to pull the power supply, and it is very convenient to install and control the power supply of the equipment indoors! It can also be used for WLAN, wireless routers, switches, Internet phones, gateways, access control, security monitoring, etc.
The principle of POE power supply through the cable: The standard Category 5 network cable has four pairs of twisted pairs, but only two of them are used in l0M BASE-T and 100M BASE-T. IEEE80 2.3af allows two usages. When using idle pins for power supply, pins 4 and 5 are connected as positive poles, and pins 7 and 8 are connected as negative poles.
When using the data pin to supply power, add the DC power to the midpoint of the transmission transfer, which will not affect the data transmission. In this way, pairs 1, and 2, and pairs 3, and 6 can be of any polarity.
The standard does not allow both cases to be applied at the same time. The power supply equipment PSE can only provide 1 usage, but the power application equipment PD must be able to adapt to both situations at the same time
