2-Way Ethernet Splitters Sell for as low as One Dollar

Ethernet Splitter

When I need to connect more than one device over Ethernet I usually think Ethernet hub or Ethernet switch. I think the former is harder to find these days but was convenient to capture Ethernet packets with Wireshark. I had however never heard about Ethernet splitters until I saw a pair sold on  Gearbest for $7.99, but soon found one on Aliexpress for just one dollar plus shipping. At first sight, it does not seem particularly useful especially when looking at the connection diagrams that show it used as some kind of Ethernet extender where you need to connect two Ethernet cables to the router, and again two cables to the targets since the same signal could be transmitted over a single cable with a $10 Ethernet switch at the other side. There’s a method to this (apparent) madness, as Cat 5E or grater cables come with 4 twisted pairs of wires, and while all 8 wires are used with …
