Ten black RJ45 female couplers in a row

BFKK

BFKK RJ45 Coupler Cat8/7/6/5 Female Black 10 Pack

SKU CH-60MQ-K048Z

Extends Ethernet links by joining two cables with ten shielded RJ45 couplers rated for 1000 Mbps and Cat6 performance

  • Extend network reach by joining two cables
  • Nickel-plated contacts resist corrosion for lasting signal
  • Cat 6 certified to TIA/EIA 568-C.2 standard
  • Supports 1000 Mbps across Cat5 to Cat8 cables
  • Ten couplers in one pack for multiple runs

BFKK RJ45 Coupler 10 Pack

This ten-piece pack of BFKK RJ45 couplers lets you join two shorter Ethernet cables into one longer run without crimping tools. Each female-to-female inline adapter accepts standard RJ45 plugs from Cat8, Cat7, Cat6, Cat5e or Cat5 cables. Nickel-plated contacts and a snap-in retaining clip provide a secure, corrosion-resistant connection. The couplers are rated for gigabit speeds up to 1000 Mbps and meet Category 6 performance per TIA/EIA 568-C.2 with RoHS compliance.

Indoor Network Extensions Only

These couplers suit home or office users who need a quick, tool-free way to extend an existing copper Ethernet link inside a dry environment. They are not waterproof, so installers running cables outdoors, through damp walls or in industrial wash-down areas should look for a sealed, weather-rated alternative. Buyers who require shielded connectors for high-EMI environments or PoE power delivery beyond the standard specification will also need a different product.

Category 6 Certified Gigabit Performance

The decisive specification is the Category 6 performance rating under TIA/EIA 568-C.2, which guarantees 1000 Mbps throughput across the mated pair. If your installation demands certified Cat6a, Cat7 or Cat8 channel performance with alien-crosstalk margins, this coupler will not meet that requirement.

Questions about this item

Should I buy a single coupler or the 10 pack?

The product is only sold as a 10 pack, giving you ten female-to-female RJ45 couplers for multiple cable extensions or spare units.

Will this coupler actually deliver 1000 Mbps on my Cat6 cable?

The coupler meets Category 6 performance and TIA/EIA 568-C.2, so it supports gigabit speeds when used with solid Cat5e or Cat6 cabling.

Does the RJ45 interface limit me to a specific Ethernet standard?

The RJ45 jack is backwards compatible with Cat8, Cat7, Cat6, Cat5e and Cat5 cables, capping at the lowest category cable you connect.
