How to Connect Two Ethernet Cables Together

If you need to connect two Ethernet cables together, you have a few options. Here’s how you can do it:

  1. Ethernet Coupler:
    • The simplest method is to use an Ethernet coupler.
    • Buy an RJ45 Ethernet coupler. This device has two female RJ45 sockets.
    • Plug each Ethernet cable into the coupler. Ensure the coupler supports the speed you need (e.g., Cat5e, Cat6, Cat6a).
    • The two cables will now act as one continuous cable.
  2. Ethernet Switch or Hub:
    • If you have an Ethernet switch or hub, you can plug both cables into it.
    • This method not only joins the two cables but also allows multiple devices to connect to the network.
  3. Patch Panel:
    • If you are working in a structured cabling environment, like an office building, a patch panel might be used.
    • Strip back the outer insulation of each Ethernet cable.
    • Punch down each cable to its respective slot on the patch panel.
    • Using a short Ethernet cable (patch cable), connect the two corresponding ports on the patch panel.
  4. Direct Splicing (not recommended):
    • This method is generally discouraged because it can degrade the signal quality and might not support high-speed connections, but it’s a possible last-resort option.
    • Strip back the outer insulation on both Ethernet cables.
    • Carefully untwist the pairs of wires. You should see four pairs (eight wires total).
    • Splice each wire to its corresponding color on the other cable. Use small wire connectors or electrical tape.
    • Make sure none of the wires are touching other pairs.
    • Shield the newly joined section with electrical tape or heat shrink tubing.
    • Remember, this method can be error-prone and may not be as reliable as using a coupler or other hardware.

Tip: When joining two Ethernet cables, ensure that the total length doesn’t exceed the Ethernet standard maximum length of 100 meters (328 feet) for optimal signal quality.

If you regularly need longer runs, consider investing in a longer single cable or using network equipment like repeaters or switches to ensure signal quality over long distances.
