Two white RJ45 female couplers with surge protection

Vszerda

Vszerda Ethernet Surge Protector RJ45 Coupler 2-Pack

SKU CH-3C11-SQ09D

A two-pack of RJ45 female-to-female couplers that extend cable runs and shield equipment from surges with eight TVS diodes at 100 Mbps

  • Protects routers and outdoor PoE antennas from lightning surges
  • Extends network runs by joining two cables into one longer link
  • Built-in 8 TVS diodes clamp abnormal voltage before it reaches equipment
  • Shielded RJ45 housing blocks EMI and RFI for cleaner signals
  • PC flame-retardant shell rated 100 V0 resists fire

Vszerda Ethernet Surge Protector 2-Pack

This two-pack provides inline surge protection for Ethernet connections. It is suited for home or small-business users who run cables outdoors or between buildings and want to shield routers, switches or PoE devices from transient voltage spikes.

Capacity and headroom

Rated for 100 Mbps data throughput, the couplers handle standard Fast Ethernet links without bottleneck. They will not pass Gigabit or higher speeds, so networks requiring 1 Gbps or 10 Gbps should use alternative protection.

What the bundled pair changes

Having two units lets you protect both ends of a single outdoor run or secure two separate cable paths at once. The female-to-female design also joins two shorter patch cables into one longer run while maintaining surge suppression across the joint.

Questions about this item

Will this surge protector slow down my existing 100 Mbps network cables?

No, the coupler supports data transmission rates up to 100 Mbps, matching the speed of your current cables without reducing throughput.

How can I confirm the surge protector is actively shielding my outdoor PoE antenna after installation?

The built-in 8 TVS anti-detonator components operate passively; normal network connectivity and the absence of surge-related equipment damage indicate the protection is functioning as intended.

Does the 2-pack include the Ethernet cables needed to connect my router and antenna, or only the couplers?

Only the two RJ45 female-to-female couplers are included; you must supply the Ethernet cables to complete each connection.
