Vszerda RJ45 Coupler Female to Female Cat7 Cat6 Cat5e Blue 5 Pack

SKU CH-NG3N-31VDH

Pack of five blue RJ45 female-to-female couplers extends Ethernet cables up to 10 Gbps for Cat7, Cat6 and Cat5e networks

  • Product colorBlue
  • Key features, , , ,
  • Extends Ethernet runs by joining two short cables
  • Supports Cat5 through Cat7 at up to 10 Gbps
  • Nickel-plated contacts resist corrosion for reliable links
  • Meets TIA/EIA 568-C.2 Category 6 performance
  • Five blue couplers included for multiple connections

RJ45 female-to-female coupler five-pack

The Vszerda pack contains five blue RJ45 inline couplers that join two Ethernet patch cords into a single longer run. Each unit accepts standard 8P8C plugs and is rated for Cat5 through Cat7 cables. The nickel-plated contacts and snap-in retaining clip give a secure, corrosion-free connection for home or office networks.

Shielded PCB and gold-plated conductors

Thickened shielded circuit boards and eight-core gold-plated copper conductors maintain signal integrity up to 10 Gbps. The couplers meet Category 6 performance under the TIA/EIA 568-C.2 standard and are RoHS compliant. Fire-retardant plastic housings add durability for repeated plugging and unplugging.

Not for keystone jacks or telephone wiring

These couplers cannot be mounted in keystone wall plates and will not work with RJ11 phone cables. They only accept RJ45 Ethernet plugs, so builders needing in-wall terminations or voice-grade connections must use different hardware.

Questions about this item

Will the nickel-plated contacts on these Cat7-compatible couplers need periodic cleaning or replacement?

The nickel-plated contacts are designed for corrosion-free operation and do not require scheduled cleaning or replacement under normal indoor use.

What is the maximum sustained data rate before the TIA/EIA 568-C.2 Category 6 limit is reached?

The coupler meets Category 6 performance up to 10 Gbps, so the 10 Gbps ceiling of the Cat6/Cat7 link is the first limit encountered.

Do the shielded housings and gold-plated conductors generate noticeable heat when passing 10 Gbps continuously?

The passive metallic shielding and gold-plated copper conductors add no active heat; the couplers remain at ambient temperature during all-day 10 Gbps traffic.
