Hi Team






We have just had a Gel Filled Cat 6 cable (outdoor Rated) put in going from the room downstairs up into the soffit and into the ceiling up stairs.


My question is do I need any sort of lighting protection I did read that Outdoor Rated Ethernet cable has shielding/ESD and lighting protection.


Should I be all good or would I be better off disconnecting the feed if there's lighting/investing in some kit to protect from lighting... Attach it somehow to the nearby ground rod from our power meter.

In general you are fine, however if going between two separate buildings then yes you should use lightning protection. 


You can purchase lightning protection devices for ethernet cables - they are about $80 and have a third connection that goes to earth. 


The unit is installed on the outside wall of the building as close as possible to where the cable enters the building through the wall. 


Ideally that would be ~30cm above the ground so the earth connection is as short as possible. 




use keywords "ethernet lightning" or "ethernet surge arrestor"
