Doubling Ethernet Ports w/ 1 Cable

post #1 of 7
Thread Starter 
After looking at my 8 wire ethernet cable and each port running 4 pins for the link can two ports be put on one cable?

With the un used wires from port a being used as the live wires for port b.

Would really cut down the amount of cables i need to route round my house to port wall boxes.

Shows that only 4 wires are used for the transmit +/- & receive +/-?
Nevermind.

If it doesn't have all 8, it isn't going to work.

Switch on both ends, or just stick a switch on the end you want to plug more than one thing into.

You could theoretically hack up something if you were using 100 mbit as non-gigabit utilizes 4 wires, but it would be completely rigged and susceptible to sucking.

^ that.

100Mb doesn't use all strands but you'd have to chop and splice cables together and potentially have huge drop outs for the new -merged- cable due to the twisted pairs not being correct.

In short, the whole thing would suck hard.

I've done this before long ago. It's a bit ghetto rigged and you lose gigabit speed and oh the crosstalk. A switch is the obvious right path to take.
