I've read a lot of things about shielding in twisted pairs cables and I feel like it's a controversial topic. I want to know the correct method to connect two devices using a F/UTP cable.
Assume a PC and a Switch, both with shielded RJ45 housing and both connected to AC power grid with 3 wires (line, neutral and ground). Keep assuming, for semplicity, that a long F/UTP cable is the only thing between these two devices (no patch panel, wall jacks, patch cords). This cable has foil and drain wire making contact with the metal shield on the RJ45 plug:
- are PC and Switch properly connected with a shielded link betweend each other, effectively reducing EMI interference?
- is a connection like this secure?
- should had I connect the drain wire not to the metallic shield of the RJ45 plug but to the ground wire of my power grid (the yellow/green wire) even if the two devices are themself grounded?
Hope someone can iron out my doubts about shielding TPs cables. Thank you
