What factors can affect the transmission distance of PoE power supply?
PoE can transmit data through a single network cable while supplying power to PoE terminal devices such as wireless APs, network cameras, IP phones, PADs, etc., with a transmission distance of up to 100 meters. Due to its simple installation and plug and play capabilities, the PoE power supply system is highly suitable for use in industries such as smart cities and security monitoring.
Twisted pair cables have an insurmountable transmission distance of 100 meters. Whether it is a Cat3 with a transmission rate of 10M, a Cat 5e with a transmission rate of 100M, or even a Cat6 with a transmission rate of 1000M, the farthest effective transmission distance is 100 meters.
Can’t the PoE transmission distance be further away?
What factors will affect its transmission distance?
What should I do when the network cable transmission distance exceeds 100 meters?
- Network cable quality
The transmission distance of a Cat 5e data signal is approximately 100 meters. Considering factors such as channel attenuation in engineering, to ensure construction quality, a distance of 80-90 meters is generally taken. The transmission distance here refers to the maximum speed, such as 100M. The power supply distance of PoE is closely related to the material of the network cable, and the lower the impedance of the network cable, the farther the transmission distance. The selected PoE switch or network cable has poor quality, which can seriously affect transmission distance and system stability.
- Cable laying and heat dissipation
The increase in cable temperature can lead to a decrease in channel attenuation and insertion loss performance. In PoE cable laying, the impact of cable laying on heat dissipation should be emphasized.
- PoE switch performance
