50-Pack Gigabit RJ45 Couplers

This 50-piece pack of black inline couplers joins two Ethernet cables into a single longer run. Each female-to-female adapter supports up to 1 Gbps data rates and works with Cat5 through Cat8 cables. The bulk quantity suits installers, IT teams, or home labs that need many reliable extensions.

Check cable type and jack style first

These couplers accept only RJ45 plugs and will not fit RJ11 telephone connectors or keystone jacks. Verify that both cables you plan to join use standard RJ45 ends and that the combined length stays within Ethernet distance limits for your desired speed.

Shielded PCB with gold-plated contacts

A thickened shielded PCB and nickel-plated contacts resist corrosion and maintain signal integrity. The snap-in retaining clip locks each plug firmly, preventing accidental disconnects during moves or vibration. PVC housing adds impact and temperature resistance for daily handling.

Questions about this item

What is included in the 50-piece pack and do I need to buy any cables separately?

The pack contains 50 RJ45 couplers; you must supply your own Cat5, Cat5e, Cat6, Cat6a, Cat7 or Cat8 Ethernet cables to connect.

How do I choose between the supported cable categories for my installation?

All listed categories from Cat5 through Cat8 are compatible; pick the category that matches the cables you already own or plan to run.

What does the 1 Gbps headline speed mean when the coupler is installed in a live network?

The coupler meets Category 6 performance and TIA/EIA 568-C.2, so it will pass gigabit traffic without signal loss when used with compliant cables.
