The maximum transmission distance of a PoE cable is usually 100 meters. This limit helps ensure reliable and stable data transmission. It also prevents delays and packet loss.
Factors affecting the transmission distance of PoE cables
Network cable quality:
The impedance, material and specifications of the network cable will affect the transmission distance of PoE power supply. The lower the impedance and the better the network cable, the longer the transmission distance can be.
Equipment performance:
The performance of the PoE switch will also affect the transmission distance. If the switch's internal chip does not adapt well and the power chip is weak, it can cause problems. Even with good network cables, it may not support longer distances.
Temperature:
The increase in cable temperature will lead to a decrease in channel attenuation and insertion loss performance. In the laying of PoE cables, the impact of cable laying on heat dissipation should be considered.
Methods to extend the transmission distance of PoE cables
Reducing the data transmission rate can help extend the distance of PoE power supply in some cases.
Good cables can reduce signal loss and distortion. This helps to extend the transmission distance.
Use special equipment: There are also some advanced PoE switches on the market that can support longer transmission distances.
