RJ45 Inline Coupler Cat 8 to Cat 5

This RJ45 inline coupler joins two male Ethernet cables to extend a network run. It suits home owners, office installers or anyone linking a TV, router, PC, switch or console without pulling new cable. The five-pack covers multiple rooms or devices.

Extends reach without signal loss

Eight aligned contacts on each side pass data through without degrading integrity or adding lag. The adapter meets Category 6 performance under the TIA/EIA 568-C.2 standard and supports speeds up to 10 Gbps when used with Cat 7 or Cat 6 patch cords.

Compact 8P8C female adapter

The small coupler fits in the palm and connects Cat 8, Cat 7, Cat 6, Cat 5e or Cat 5 patch cords. Builders who need shielded Cat 8 performance or PoE power delivery should verify those requirements separately.

Questions about this item

Will the RJ45 contacts degrade after many insertions?

The gold-plated 8P8C contacts are rated for repeated mating cycles; keeping them clean and avoiding side-load insertion preserves signal integrity over time.

What throughput ceiling appears first during continuous 10 Gbps traffic?

The coupler meets Category 6 performance per TIA/EIA 568-C.2, so sustained 10 Gbps runs are limited by the Cat 6 specification rather than the coupler itself.

Does the coupler generate heat or noise when powered all day?

As a passive component with no active electronics, it produces no heat and makes no noise regardless of how long data flows through it.
