What is the difference between a keystone jack and a keystone coupler?

The key difference between a keystone jack and a keystone coupler lies in their functionality and installation method:

Keystone Jack:

  • Purpose: Used to terminate Ethernet cables without the need for a punch-down or crimping tool.
  • Example Product: Cat6 Keystone Jack, 12-Pack or Cat6A Keystone Jack, 12-Pack.
  • Features:
    • Toolless termination.
    • Compatible with TIA-568A and 568B wiring standards.
    • Suggested cable gauge: 23–26 AWG.
    • Material: Polycarbonate (Cat6) or Zinc Alloy (Cat6A).

Keystone Coupler:

  • Purpose: Acts as a pass-through connector to join two pre-terminated Ethernet cables seamlessly.
  • Example Product: Cat6 Keystone Coupler, 12-Pack or Cat6A Keystone Coupler, 12-Pack.
  • Features:
    • No termination required; simply plug in pre-terminated cables.
    • Material: Polycarbonate (Cat6) or Stainless Steel (Cat6A).

Summary:

  • Keystone Jacks are for terminating raw Ethernet cables, while Keystone Couplers are for connecting pre-terminated cables.
