Joining two ethernet cables: strip and solder or buy an adapter?

CAT5e/6 junction boxes are available for splicing cables without needing to terminate, twist, or soldier.

Junction boxes are better for permanent cabling, as they're more secure than terminated ends paired with a coupler, or twisted/soldiered. Cables with these junction boxes won't be pulled apart at the splice point, unlike with other splice methods.

Examples:

  • Punch-down junction box
  • Punch-down 110 block
  • Punch-down shielded 110 block

Note: I've never actually purchased from any of these particular storefronts. I'm simply linking to them to show examples of junction boxes.
