Vszerda RJ45 Shielded Coupler Extender 10 Gigabit 8 Tube

SKU CH-RPEF-FVDKE

A shielded RJ45 coupler extends two Ethernet cables while eight protection tubes guard connected equipment against lightning surges up to 10 gigabit speeds

  • Extends Ethernet links with shielded RJ45 coupler
  • 8 lightning-protection tubes guard against surge damage
  • Supports 10 Gigabit speeds for future-proof networks
  • Gold-plated contacts resist corrosion for reliable connection
  • Compatible with Cat7, Cat6 and Cat5e cables

Shielded Coupler for 10-Gigabit Networks

This shielded RJ45 coupler joins two Ethernet patch cables and supports speeds up to 10 gigabit. It is built for Cat7, Cat6, Cat5e and Cat5 cabling. The gold-plated contacts and snap-in clip provide a secure, corrosion-free link. Eight lightning-protection tubes on the PCB help guard connected equipment from surge damage.

Sustained Load Behaviour

The coupler maintains Category 6 performance during continuous data transfer without active cooling. Shielding reduces alien crosstalk when cables run alongside power lines or other pairs. Gold plating resists oxidation that can degrade signal integrity over time. The inline design adds no active components that could throttle throughput under prolonged use.

Practical Interface Limits

The RJ45 interface caps throughput at the 10 gigabit rate supported by the connected cable category. Shielding effectiveness depends on both cables and the coupler being properly grounded at each end. Lightning tubes clamp transient voltage but do not replace whole-building surge protection. Maximum segment length remains governed by the cable standard in use.

Questions about this item

Will the 8 lightning protection tubes keep the coupler running cool during constant 10 Gbps traffic?

The 8 tubes are surge protection components, not heat sources. The passive coupler adds no active cooling load and draws no power, so it stays at ambient temperature.

Do I need shielded Cat6 or Cat7 patch cables on both sides for the shielding to work end-to-end?

Yes. The coupler’s metal housing and gold-plated contacts require shielded cables on both ports to maintain a continuous ground path and meet Category 6 performance.

Can I join a legacy Cat5e run to a new Cat6a drop without losing the 10 Gbps rating?

The coupler is rated for 10 Gbps with Cat6 or Cat7. Using Cat5e on either side will limit that link to its lower category speed.
