I need to set-up a home network. The flat we moved in recently has a media connection ability for each room, but not all rooms are equipped. This meant I had to fill the empty tubes and get the wiring done myself. Two problems:
- How long are the tubes … how long does the cable need to be?
- The tubes are narrow in diameter and have bends which made it impossible to pull through Ethernet cables with the plug.
Solution:
- Buy Ethernet cable
- Buy RJ45 plugs and the related tools
- Pull cable through
- Get plug on each end of the cable
- Job done
Sounds easy, but I wanted to be sure that I do the right thing – so I had the following questions:
- Which wires are necessary as a minimum to enable a 1000 Mbps network connection.
- What is the largest length allowed?
- What is the smallest cable quality?
- Which plugs need to be used?
- How should I connect the plugs?
Answers:
- Always a good starting point: Wikipedia with information for Gigabit Ethernet
- Max. 100m cable length, but the transfer quality of a patch cable is worse and therefore max. length is recommended to a max. of 70m.
- Cable quality: min. Cat-5 cable, better Cat-5e!
- Plugs: standard RJ45
- Very good private page: Manual Kanish hatte wohl das gleiche zu tun wie ich;-).
- Use Patch standard: 568B diagram
- Beware: Clip on button – contacts to the top … then orange cable – pin 1 is the first contact on the left.
