The only reason to do this is if you really need two different physical connections and only have one cable. Note that these is no communication between the two NICs on the left side. This most likely will run your cable out of spec and the connection may be unreliable. If we want to do ugly things then we can try to use one 8-wire cable as two 4-wire cables. Splitters.īest guess on that these do, depending on splitters I have seen in the past:Įthernet cable has 8 wires. 4 specific ones with well defined twist rates in the cable. Ethernet cables usually have 8 wires in them and for 10 and 100mbit connections only 4 are used. Your theory is wrong, and what you REALLY need is a switch.Ī router or a switch connect to different devices. Used it, so I need confirmation that it work or not before I'll buy Signal, but send it to all clients (like a splitter would). In theory it should work like an Ethernet hub, which only amplifies well is a fairly dumb device that turns one cable into 'two'. A switch takes in data and switches packets only where they need to go (which is faster and more secure). It will absolutely not work for Gigabit (1000Base) Ethernet, as that requires all 8 strands.Ī hub and a switch are very different things.Ī hub takes in data and retransmits it to all the ports (and I've never seen a fast Ethernet hub, let alone gigabit). It will take up two ethernet ports on the far end. Practically this might drop down to 10BaseT speeds, and you need to use a splitter on both ends for it to work. It turns one 8-strand ethernet cable into a what would be, essentially, a pair of sub-standard 4-strand cables that in theory should do Fast Ethernet (100BaseT/TX). It's useful to understand what a splitter does. Start doing non-standard, non-compliant things, and you will end up getting non-standard, non-compliant, unexpected results. However, the Ethernet wire protocol has been designed to use twisted pairs in such a way that cross-talk is eliminated between the wires. There were other search results which mapped the two unused pairs (1
