BFKK

BFKK RJ45 Coupler Ethernet Extender Female to Female 30 PCS Black

SKU CH-F7FF-5896P

A pack of thirty inline RJ45 couplers that join two Ethernet cables for a shielded Cat6 connection up to 1 Gbps

  • Connect two cables to extend network reach
  • Plug-and-play setup delivers up to 1 Gbps speed
  • Nickel-plated contacts with snap-in clip prevent corrosion
  • Meets Category 6 performance per TIA/EIA 568-C.2
  • Full-metal shielding blocks electromagnetic interference

Ideal Network Extension

This pack provides thirty RJ45 female-to-female couplers designed to join two shorter Ethernet cables into a single longer run. The adapters suit home offices, small businesses or temporary setups where existing patch leads fall short of the required distance. Each unit works straight out of the box with no driver installation needed. The black finish keeps the installation looking tidy in visible locations.

Cat6-Rated Performance

Every coupler meets Category 6 performance and complies with the TIA/EIA 568-C.2 standard while maintaining backward compatibility with Cat8, Cat7, Cat5e and Cat5 cables. Nickel-plated contacts and a secure snap-in retaining clip deliver a corrosion-free connection that preserves signal integrity. Full-metal shielding surrounds the eight precisely aligned conductors to block external electromagnetic interference. The design supports data rates up to 1 Gbps without degradation.

Durable Passive Operation

High-quality ABS housing adds flame-retardant protection and mechanical stability during daily handling. Pure copper-plated contacts ensure strong signal transmission across the junction. Because the couplers are completely passive, they draw no power and generate no heat or audible noise. The compact form factor makes them easy to carry in a tool bag for on-site wiring tasks.

Questions about this item

What does the Category 6 rating mean for my network speed?

The coupler meets Category 6 performance and is compatible with the TIA/EIA 568-C.2 standard, supporting data rates up to 1 Gbps on Cat6, Cat5e, Cat5, Cat7 and Cat8 cables.

Does the TIA/EIA 568-C.2 standard limit the bandwidth I can use?

The standard defines the pin-out and performance requirements for Category 6 links, so the installed channel runs at up to 1 Gbps with the cables listed.

What physical space or mounting does this coupler need?

Each unit is a compact female-to-female inline jack with a snap-in retaining clip; it simply joins two RJ45 plugs and requires no extra mounting hardware.
