Vszerda 3 Pack RJ45 Ethernet Coupler Female to Female Cat7 Cat6 Cat5e Cat5

Extending Ethernet Connections

The Vszerda three-pack provides female-to-female RJ45 couplers that join two shorter network cables into a single longer run. Each unit is gold-plated and shielded to maintain signal quality across the link. They are aimed at home and office users who need a quick, tool-free way to bridge a gap without buying a new pre-made cable.

Capacity and Headroom

Rated for up to 1 Gbps throughput, the couplers remain backwards compatible with 100 Mbps and 10 Mbps networks. The supplier states that a joined run can reach 328 ft without speed reduction, so typical room-to-room or desk-to-router distances are well within comfortable headroom. Very long runs approaching the stated limit may still be affected by cable quality and environmental interference.

RJ45 Coupler Practical Limits

Because the device is a passive mechanical junction, it cannot amplify or regenerate a weakened signal. Performance depends entirely on the category and condition of the cables plugged into it; using Cat5 cable will cap the link at 100 Mbps even though the coupler supports gigabit speeds. Buyers who need powered signal extension or fibre conversion will need active networking hardware instead.
