10-piece RJ45 coupler pack

This pack contains ten straight-through RJ45 couplers that join two Ethernet cables together. Each unit accepts Category 5, 5e, 6 and 6a patch leads so existing runs can be extended without re-termination. The couplers are passive components requiring no power or configuration. They suit installers and home users who need quick cable extensions.

Plastic housing and bulk quantity

The moulded plastic shells protect the internal contacts while keeping each coupler light at roughly 50 grams for the full set. With ten pieces supplied, multiple junctions can be created across a site or several spares kept in a tool bag. No software, drivers or additional hardware are included or required for operation.

Compact straight-through design

Each coupler measures 3.2 by 2 by 1.5 centimetres, allowing it to sit inline behind desks or inside trunking without adding bulk. The straight-through pinout preserves the original cable wiring standard for reliable data transmission. Builders needing angled connectors, shielded housings or PoE power injection should look for specialised alternatives.

Questions about this item

Will the plastic housing or RJ45 contacts need replacement after repeated unplugging?

The coupler uses a plastic shell and standard RJ45 ports rated for typical mating cycles; no user-serviceable parts are inside.

What signal limit appears first when joining two CAT 6a cables with this coupler?

Each coupler adds insertion loss and return loss, so the combined run reaches the channel attenuation budget before the individual cable rating.

Does the coupler generate any heat or noise when left connected continuously?

It is a passive plastic connector with no electronics, so it produces zero heat and no audible noise during all-day operation.
