SKU CH-Z6SK-A7MHF

Ten couplers join two Ethernet cables for runs up to 10 Gbps across Cat7, Cat6 and Cat5e

  • Variant10 Pack
  • Extend Ethernet runs by joining two short cables together
  • Supports speeds up to 10 gigabit on Cat7 and Cat6 links
  • Nickel-plated contacts with snap-in clip give secure, corrosion-free connections
  • Works with Cat7, Cat6, Cat5e and Cat5 network cables
  • Meets Category 6 performance per TIA/EIA 568-C.2 and is RoHS compliant

10-Pack RJ45 Coupler Set

This 10-pack of RJ45 female-to-female couplers joins two shorter Ethernet cables into a single longer run. Each coupler uses nickel-plated contacts and a snap-in retaining clip to hold the connection firmly. The black housing is made from high-impact, fire-retardant plastic. The set is intended for installers or home users who need to extend existing patch cables quickly.

Suited to Cat5e through Cat7 patch cables

The couplers accept standard 8P8C plugs from Cat5e, Cat6, Cat6a and Cat7 cables, so they work with most installed wiring. They are not designed for outdoor burial, industrial vibration zones or shielded-conduit systems that require grounded metal backshells. Buyers who need PoE++ current handling above the connector rating or IP-rated ingress protection should look at purpose-built industrial connectors instead.

Meets TIA/EIA 568-C.2 Category 6 performance

Compliance with the 568 standard confirms the coupler passes the crosstalk and return-loss limits required for Category 6 links. This single specification determines whether the adapter will maintain the speed and reliability of the cable run it extends.

Questions about this item

Do the couplers generate any heat or draw power when used continuously?

The couplers are passive components with no power draw and produce no heat during continuous operation.

What cables must I already have to use these couplers?

You need two Ethernet cables with RJ45 plugs — Cat5e, Cat6 or Cat7 — to join together with each coupler.

Will these couplers work with the Cat5e patch cables I already own?

Yes, the couplers are backward compatible with Cat5e, Cat6 and Cat7 cables and meet Category 6 performance per TIA/EIA 568-C.2.
