I’ve decide to try and relocate the control panel. After a bit of a faff, managed to get to the other side of the old control panel. So my intention is to extend the two existing erthernet or network cables to the new position.

Having never worked with the stuff, what is the best method and product to use to join them? I’ve seen some vids of just twisting the cores, but that seems a bit of a bodge.

I’ve also seen coupler boxes, which look just like telephone line boxes. Is just as simple as that?
 
The punch down type joint boxes are fine as far as I know, especially if it's not high speed data traffic.
Solder and heatshrink works well as you can maintain the twisted pairs through the joint.

Not really sure what this panel uses. Ex-Or say the control panel can be hot swapped, but I'm gonna wait for the commissioning bod to turn before doing so. Might need to shutdown the main panel, so want something quick & simple to use.
 
Just remember, when connecting the cable to any connection box, keep the cables twisted for as long as possible.
 
Too many connections for my liking

Thats how to do it correctly, .cant do hot works etc in datacentres etc... they are usually in a 1u panel full of them inside a cabinet, but essentially thats it. that way you dont damage the signals by using out of spec materials such as solder or the infamous BT jelly crimps.

That or run a new cable, which is ofcourse the preference.
 
The cheap 1 pound inline couplers seem to work fine. Plus you keep untwisted pairs as short as possible.
