  • Extends Ethernet runs by joining two cables

  • Nickel-plated contacts and snap-in clip give secure, corrosion-free links
  • Shielded housing resists electrical interference

Female-to-Female RJ45 Coupler

This BUCIER coupler joins two Ethernet cables with RJ45 plugs to create a longer run. It is built for installers and home users who need to bridge a gap without crimping a new cable. The pack contains two units so a spare is on hand for the next job. No drivers or configuration are required; the connection is purely passive.

Plug-and-Play In-Line Extension

The adapter sits inline between two patch cords and needs no external power or keystone mounting. It frees the builder from pulling a single long cable through walls or conduit by letting shorter, pre-terminated leads be linked on site. Nickel-plated contacts and a corrosion-resistant housing preserve signal quality in typical indoor environments. The snap-in retaining clips keep each plug locked in place during handling.

Cat7-to-Cat5e Compatible Headroom

The coupler is rated for Cat7, Cat6, Cat5e and Cat5 cables, so it supports gigabit and multi-gigabit links up to the cable’s own specification. It cannot be used with RJ11 telephone plugs or inserted into a keystone jack, limiting it to direct cable-to-cable joins. Buyers needing PoE power negotiation, shielded keystone integration or outdoor-rated sealing will need a different product.

Questions about this item

Will the plastic housing or contacts degrade first when the coupler is left in place for months?

The housing is described as corrosion-resistant and the contacts are nickel-plated, so neither is expected to degrade quickly under normal indoor use.

Does the coupler get warm or draw any power when data passes through continuously?

It is a passive component with no electronics, so it generates no measurable heat and consumes no power during operation.

What type of Ethernet cables must I already have to use this coupler?

You need two standard RJ45-terminated cables rated Cat5, Cat5e, Cat6 or Cat7; RJ11 phone cables and keystone jacks will not work.
