Re: More speed!
I have been considering upgrading to a 10gb lan (I have cat6 cables)
IEEE 802 back in 2014 finally agreed to take Plastic Optical Fibre (POF) seriously. POF has been around since the late 1980's, but was focused on the 'traditional' fibre infrastructure; POF was equivalent to quartz fibre over sub 1km distances. However, it seems that someone finally woke up and realised that it could be used as an alternative to RJ45.
Whilst current implementations are sub 150Mbps, the focus is getting agreement on a 1Gbps standard, after which I would presume people will want to push it...
So whilst not an off-the-shelf solution today, worth watching "this space".
