Terminology

Often the market describes Modular Jack connectors as 'RJ45', it has become a common term, the below section provides clarification:

  • Common versions:
  • RJ-9 or an RJ-22—both incorrect, there is no valid Registered Jack number for 4P4C.
  • RJ11: 6 positions 2 centre positions loaded.
  • RJ12: 6 positions, 6 loaded.
  • RJ13 : 6 positions, 4 centre positions loaded.
  • RJ45: 8 positions, 8 loaded. Not correct, often called 'RJ45' just resembles true RJ45, 8/8 is actually officially RJ49, 61 or others. RJ 45 is truly 8/2. Although the market knows 8/8 as RJ45.
  • RJ50: 10 positions, 10 loaded (unofficial).
