Vszerda 30 RJ45 Couplers Blue Cat8/7/6/5e/5

SKU CH-ZBPA-4NVMH

A pack of thirty blue RJ45 couplers that join two Ethernet cables into one longer run without signal loss

  • ColorBlue
  • Weight0.5 ounces
  • Extends network reach by joining two short cables
  • 30 couplers per pack for multiple installations
  • Gold-plated copper contacts deliver steady signal transmission
  • Shielded construction with thickened PCB resists interference
  • Snap-in retaining clip ensures secure corrosion-free connection

30-Pack RJ45 Inline Couplers

This 30-piece set of female-to-female RJ45 couplers joins two shorter Ethernet cables into a single longer run. The blue housings are made from impact-resistant PVC and accept Cat5 through Cat8 cords. Each coupler is plug-and-play with no drivers required and weighs 0.5 ounces total per unit.

Category 6 Performance Under Load

The couplers meet TIA/EIA 568-C.2 Category 6 performance, supporting data rates up to 1 Gbps across the extended link. Eight pure copper gold-plated contacts on a thickened, metallically shielded PCB maintain signal integrity during sustained transfers. Nickel-plated contacts and snap-in retaining clips resist corrosion and keep the connection secure over time.

Passive Thermals and Zero Power Draw

As completely passive components, the couplers add no active heat, fan noise or electrical draw to the network path. The shielded PCB and PVC housing dissipate any minimal contact warmth naturally. They are not compatible with RJ11 phone cables or keystone jacks, so buyers needing those interfaces must look elsewhere.

Questions about this item

Will these blue RJ45 couplers add heat or noise when running continuously?

No, the couplers are passive connectors with no electronics, so they generate no heat, noise or power draw.

What cables do I already need to use these 30 female-to-female couplers?

Two Ethernet cables with RJ45 plugs — Cat5, Cat5e, Cat6, Cat6a, Cat7 or Cat8 — are required for each coupler.

Can I join an old Cat5 patch cord to a new Cat6a run with these adapters?

Yes, each coupler accepts any mix of Cat5 through Cat8 RJ45 cables and meets Category 6 performance per TIA/EIA 568-C.2.
