Two black RJ45 female-to-female couplers, rectangular plastic bodies with nickel-plated contacts

BUCIER

BUCIER RJ45 Coupler Ethernet Cable Extender Adapter Cat7 Cat6 Cat5e Black 2 Pack

SKU CH-RP5J-NGZXT

Female-to-female RJ45 coupler joins two Ethernet cables up to 10 Gbit/s, meets TIA/EIA 568-C.2 Category 6 performance, nickel-plated contacts, black two-pack

Model 2 pack

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

Two-Pack RJ45 Coupler

This two-pack of RJ45 female-to-female couplers joins two shorter Ethernet cables into a single longer run. Each unit is built from high-impact, fire-retardant plastic with nickel-plated contacts and a snap-in retaining clip. The couplers accept Cat7, Cat6, Cat5e and Cat5 patch cables. They are RoHS compliant and meet TIA/EIA 568-C.2 Category 6 performance requirements.

Sustained 10 Gbit/s Throughput

The adapter supports data rates up to 10 Gbit/s when used with Cat7 or Cat6 cabling, maintaining that speed across the mated connection without signal degradation. Nickel-plated contacts resist corrosion so the link stays reliable during continuous high-bandwidth transfers. The inline design adds no active circuitry, so latency and error rates remain identical to an unbroken cable of the same total length.

Category 6 Compliance Decides Fit

If your installation must meet Category 6 performance per TIA/EIA 568-C.2, these couplers satisfy that requirement; if the project demands Category 6A or higher certification, this part does not qualify. Buyers needing shielded couplers for noisy environments should look elsewhere, as the housing is unshielded plastic. The two-pack format suits a single extension point; larger deployments will require additional packs.

Questions about this item

Does the coupler add any heat or power draw when it sits in a 10 Gbps link all day?

It is a passive component with no electronics, so it draws no power and generates no heat regardless of how long the link runs.

What cables and connectors must I already have to use this female-to-female 8P8C coupler?

You need two Ethernet patch cables terminated with standard RJ45 plugs — Cat5, Cat5e, Cat6 or Cat7 all work.

Will this Category 6 compliant coupler slow down a legacy Cat5e run that I want to extend?

It meets TIA/EIA 568-C.2 Category 6 performance, so a Cat5e link will run at its normal 1 Gbps rate without degradation.
