Ethernet couplers don’t lower speed. They can cause more defective packets if the cable length is around 100 meters. An increase in defective packets reduces throughput because of packet re-transmission, but speed remains the same. Can you run two devices off one Ethernet? You don’t need to buy heavy cableRead More →

A cable splitter WILL result in a degradation of the signal, even if the other ports are unused. One thing you can do is to add terminator caps to each unused port. They are supposed to reduce the degradation. Note that cheaper cable splitters will actually have a different amountRead More →
