ESTONE

ESTONE RJ45 Coupler Female to Female 2 Pack

SKU CH-31GA-KEMZK

Female-to-female RJ45 coupler joins two Ethernet cables, supports up to 10 Gbit/s with Cat7 or Cat6, and meets TIA/EIA 568-C.2 Category 6 performance

  • Option2 pack

Option 2 pack

  • Extends Ethernet links by joining two cables together
  • Supports up to 10 Gbps over Cat7 or Cat6 wiring
  • Nickel-plated contacts with snap-in clip resist corrosion
  • Works with Cat7, Cat6, Cat5e and Cat5 networks
  • Meets TIA/EIA 568-C.2 Category 6 performance and RoHS compliance

Extending Ethernet Connections

This coupler joins two RJ45 cables to create a longer run without rewiring. It suits installers and home users who need to bridge a gap between existing Cat5e, Cat6 or Cat7 patch leads. The 8P8C female-to-female design accepts standard connectors on both sides for a straight-through link.

Sustained Signal Integrity

Nickel-plated contacts resist corrosion so the connection stays reliable over extended use. The housing uses fire-retardant plastic rated for continuous operation. Performance meets Category 6 requirements under the TIA/EIA 568-C.2 standard, supporting data rates up to 10 gigabite across the full link.

Category 6 Practical Limits

The coupler complies with the 568 standard for Cat6 performance, but total channel length still governs maximum throughput. Shielding and cable quality determine whether 10 gigabite speeds hold over the complete run. It will not compensate for runs that exceed the standard's distance allowance or for cables rated below Cat6.

Questions about this item

Does the coupler generate any heat or draw power when used continuously?

The coupler is a passive component with no power requirement and produces no measurable heat during extended use.

What cables or connectors must I already have to use this coupler?

You need two Ethernet cables with standard RJ45 plugs — Cat5, Cat5e, Cat6 or Cat7 — to join through the female ports.

Will this coupler work reliably with older Cat5 cable I still have installed?

Yes, the coupler is compatible with Cat5, Cat5e, Cat6 and Cat7 cables and meets Category 6 performance per TIA/EIA 568-C.2.
