RJ45 Shielded Coupler 30 Pack
This 30 pack of RJ45 shielded female-to-female couplers connects two male Ethernet cables to extend a run. Each 8P8C jack is compatible with Cat7, Cat6, Cat5e and Cat5 network cables. The metallic shielding prevents electrical interference for a stable connection. They meet Category 6 performance and are verified to TIA/EIA 568-C.2.
Inline Extender for Existing Cables
The couplers plug directly into terminated cables without tools or configuration. They free you from pulling new long runs when a cable falls short at home or in the office. Each unit uses full metal shielding and gold-plated contacts inside an ABS housing. The compact size makes them easy to carry in a tool bag for on-site wiring jobs.
Passive Component Thermals
As a passive component the coupler draws no power and generates no heat or noise during operation. The shielded metal body dissipates any minimal signal loss without active cooling. Network speed supports up to 10 Gbps through the 8P8C interface. RoHS compliance confirms restricted substances are absent from the materials.

Questions about this item
Does the coupler maintain 10 Gbps speed when two cables are joined for a long run?
The coupler meets Category 6 performance and TIA/EIA 568-C.2 verification, supporting up to 10 Gbps across the connection.
Will the metal shielding get hot or add noise when the link runs continuously?
The full metal shield is passive and grounded through the cable screens, so it adds no heat or audible noise during all-day operation.
What cable types must I already have for these couplers to work?
You need two male-terminated Ethernet cables — Cat7, Cat6, Cat5e or Cat5 — each with an 8P8C RJ45 plug.
