Network cables and power cables are two different types of cables that are often used for different purposes. Network cables (also known as Ethernet cables or network cables) are mainly used to transmit data and enable computers, routers, switches and other network devices to communicate with each other. The power cord is used to provide power to the device.
If you mean to ask if there is a cable that can carry both data and power, then the answer is yes. This type of cable is useful in certain applications, especially where there is a need to reduce cable clutter or where it is difficult to route separate power supplies. The following are some related technologies and application scenarios:
PoE (Power over Ethernet): PoE technology allows network cables (such as Cat5e, Cat6 and other Ethernet cables) to transmit data while also powering devices. This technology is widely used in wireless access points (APs), IP cameras, VoIP and other devices because it simplifies installation and reduces costs, especially in locations without convenient power access.
Working principle of PoE: PoE equipment is divided into two categories, PSE (Power Sourcing Equipment) and PD (Powered Device). The PSE device is responsible for providing power (such as a PoE switch), while the PD device is the device that receives power (such as an IP camera). Standard PoE can provide up to 15.4 watts of power, while PoE+ (802.3at) can provide up to 30 watts of power, which is enough for most devices that need to be powered through the network cable.
Precautions for selection and use:
Compatibility: Make sure your device supports PoE and check that the required power level matches your PSE device.
Cable quality: Use high-quality, standards-compliant network cables to ensure reliable power and data transmission.
