Shielded Cabling & PoE?
While we’ve been through the EMI and mechanical strength that the various braided and shielding options bring, we have neglected to mention PoE.
PoE has become a buzzword for the industry.
Hugely gaining traction, Power over Ethernet (PoE) allows you to power remote devices such as IP Phones, CCTV Cameras and Lighting with the same cable that provides the network connection.
I’m sure you’re wondering what that has to do with shielding…
Well along with larger conductor sizes, shielding being present aids the installed cable is keeping cool.
Through laboratory testing, it’s been established that the presence of a metallic braid or foil helps to dissipate the heat.
Therefore, while it’s not the only thing you should consider when implementing a PoE ready network, a shielded system should be high on your list of considerations.
