I realise it goes against best practice when it comes to network cabling (to run it parallel alongside power cabling) due to AC coupling, however I've come across a situation at home where I can either:
i. Run it alongside 20 amp (240v) AC power cables for a distance of no more than 2 metres (power and ethernet within their own separate plastic conduits) and have the installation look neat and tidy, or,
ii. Run the ethernet cabling via an indirect route, avoiding power cabling, but have the installation look untidy and messy.
The cable I'm using is Clipsal unshielded solid core Cat 6. The entire cable run (from device to switch) would be no longer than 25 metres (with only 1-2 metres actually running alongside power cabling). Signalling rate will be 100Mbps and the data is non-critical so a few re-transmitted frames every so often won't cause problems. I'm also using proper enterprise-grade Cisco switches.
In reality, will this cause any issues in this circumstance? Will the error rate still be low enough not to worry about?
