  • Product colorBlack
  • Product weight0.45 oz
  • Extend network reach by joining two short cables
  • Gigabit speeds up to 1 Gbps with zero signal loss
  • Works with Cat5 through Cat8 Ethernet cables
  • Nickel-plated contacts and snap-in clip prevent corrosion
  • 100 couplers in one pack for large installations

100-Pack Gigabit RJ45 Coupler

This pack supplies one hundred female-to-female couplers for joining two shorter Ethernet cables into a single longer run. The adapters are aimed at installers, IT teams and home users who need a quick, tool-free way to extend Cat5 through Cat8 links without rewiring walls or buying custom-length patch leads.

Thermals Noise and Power Draw

As passive inline connectors the couplers draw no power, generate no heat and produce no audible noise during operation. Signal integrity is maintained up to 1 Gbps across the mated pair, so normal data traffic passes through without added latency or degradation.

Build Quality and Daily Use

Each unit uses a thickened PCB with metallic shielding, gold-plated copper contacts and a snap-in retaining clip for a secure, corrosion-resistant fit. The black PVC housing resists impact and temperature extremes. Note that the couplers cannot be used with keystone jacks and are not compatible with RJ11 telephone cables.

Questions about this item

How do I install the Vszerda RJ45 coupler to extend my Cat6 cables, and what step is commonly missed?

Snap each cable into the female ports until the retaining clips click; the step often missed is verifying both clips are fully latched to prevent intermittent signal loss.

What maintenance will these 100 black couplers need over time?

No routine maintenance is required; the nickel-plated contacts resist corrosion, so simply inspect the snap-in clips for wear if cables are frequently reconnected.

What limit appears first when running sustained 1 Gbps traffic through the Category 6 rated inline jack?

The TIA/EIA 568-C.2 Category 6 performance ceiling caps throughput at 1 Gbps, so sustained loads cannot exceed that bandwidth.
