Five black RJ45 female-to-female inline couplers in a row

ESTONE

ESTONE RJ45 Coupler Female to Female 5 Pack

SKU CH-5Z8V-EFH9P

Pack of five shielded RJ45 female-to-female couplers that join two Ethernet cables for runs up to 10 Gbps

  • Option5 pack

Option 5 pack

  • Extends cable runs by joining two short Ethernet cables
  • Supports up to 10 Gbps with Cat6 and Cat7 cables
  • Nickel-plated contacts and snap-in clip give secure corrosion-free links
  • Meets Category 6 performance per TIA/EIA 568-C.2 standard
  • RoHS compliant and built from fire-retardant plastic

Five-Pack RJ45 Coupler Kit

This pack contains five RJ45 female-to-female couplers designed to join two Ethernet patch cables into a single longer run. Each unit uses 8P8C contacts with nickel plating and a snap-in retaining clip for a secure, corrosion-resistant connection. The moulded housing is high-impact, fire-retardant plastic. The couplers are compliant with the TIA/EIA 568-C.2 Category 6 standard and RoHS compliant. They suit installers and home users needing quick cable extension without re-termination.

Category 6 Performance Ceiling

The couplers are verified to the TIA/EIA 568-C.2 Category 6 specification, so the link will only perform to Category 6 limits even when Cat7 or Cat6a cables are used. Maximum supported throughput is 10 Gbps, but only over the shorter distances that Category 6 cabling allows. The adapter adds an extra connection point, which increases insertion loss and near-end crosstalk on the channel. Installers must account for this extra loss in their total link budget to keep certification valid.

Not For Permanent Structured Cabling

These in-line couplers are not a substitute for a proper keystone jack and patch-panel termination in permanent building wiring. They introduce a mated connector pair that cannot be tested or certified like a single continuous cable run. Buyers who need a permanent, standards-compliant horizontal link should use solid-core cable terminated at both ends instead. The product is intended for temporary extensions, lab setups or patching between two pre-made patch cords.

Questions about this item

Should I choose the 5 pack or is there a single coupler option?

Only the 5 pack is listed; each pack contains five identical female-to-female RJ45 couplers.

What does the 10 Gbps figure mean when I use this coupler with Cat6 cable?

The coupler is rated for up to 10 Gbps and meets Category 6 performance per TIA/EIA 568-C.2, so it will not bottleneck a Cat6 link running at that speed.

Which Ethernet standard does the RJ45 interface follow, and what does it cap in practice?

It follows the TIA/EIA 568-C.2 standard for Category 6, limiting the connection to Category 6 performance levels.
