alexander3133For 4 wire LAN cable, is this good enough to transmit power when connected POE ports/adapter?
Or needs 8 wire LAN cable?
Honestly I do not know if 4 wires LAN cable will work for POE, best is to get the 8 wires LAN cable.
If you have cost concern, just get the normal 8 wires Cat5 LAN cable, it will work with POE.
According to Wikipedia, POE is achievable using 4 wires LAN cable, but only on 10/100 mode A.
Again I don't know what your POE port/adapter uses which mode, to be on the safe side, just get the 8 wires LAN cable.
The 10 wires cable picture you posted is actually 8 wires normal LAN cable + 2 wires power line, merged into a "single" cable. Normally you would use this if your setup or device does not support POE, hence you have to use normal power lines to power up your device.
