When it comes to selecting network cables for Power over Ethernet (PoE) applications？

When it comes to selecting network cables for Power over Ethernet (PoE) applications
generally speaking
any type of twisted pair cable
can be used directly with PoE devices
However, it is more advisable to use
oxygen-free copper (OFC) network cables for connecting power sourcing equipment (PSE) and powered devices (PD)
Taking a 100-meter length as an example
the internal resistance of copper-clad aluminum (CCA) cables is approximately 28Ω
making them suitable only for short-distance PoE power supply
Moreover, CCA cables have poor oxidation resistance and a shorter service life
In contrast, the internal resistance of oxygen-free copper cables over the same distance is about 10Ω
representing a 40% reduction in resistance
This allows for longer signal transmission distances and lower packet loss rates
Therefore, it is crucial to choose reliable brands
to ensure that the cable materials meet industry standards
