UGREEN RJ45 Coupler Review: Keeps 10Gbps Speed and Supports PoE++

⚡ At a Glance

• • Transmission Speed: Maintains up to 10Gbps over compatible Cat5e–Cat7 cables
• • Best for: Network installers and homeowners who need quick cable joins
• • Not ideal for: Environments that require active surge protection or inline electronics

Shielded female-to-female joiner compatible with Cat5e, Cat6, Cat6a and Cat7 cables. Engineered for 10 Gigabit transmission and PoE++ with optimised pin and PCB layouts for stable data and power transfer.

Stable High-Speed Links – Thanks to 10 Gigabit transmission support

Up to 10Gbps compatibility works with Cat5e through Cat7 cable types, while the Z-shaped PCB layout shortens the signal path to reduce loss. The arched pin design separates insertion, contact and transmission points to improve electrical reliability.

Maintains full cable bandwidth for demanding tasks such as large-file transfers and high-definition streaming, reducing bottlenecks when two cable runs must be joined.

Simplified Powered Installations – With PoE++ support

PoE++ capability allows power to pass over the Ethernet link without an additional power supply when used with compatible PoE sources and powered devices. Power and data contact points are engineered to remain stable under load.

Makes fitting PoE cameras or access points quicker and neater by avoiding separate power cabling, especially useful where a powered endpoint is hard to reach.

Robust Construction for Longevity – With PA6+30GF core and 304 stainless steel shell

PA6+30GF core material increases mechanical strength and resists high temperatures and corrosion, while the 304 stainless steel shielding adds corrosion resistance and effective screening against interference. The component meets a V2 flame-retardant rating for improved safety.

Built to withstand repeated installations and hostile environments, reducing the likelihood of premature failure and the need for replacements.

✨ The 4 Key Reasons for UGREEN RJ45 Coupler

1. PoE++ support – Powers cameras and access points without separate power supplies.
2. Arched pin design – Ensures stable contact for both data and power transmission.
3. Z-shaped PCB layout – Shortens signal path to preserve high-speed throughput for demanding network tasks.
4. Durable PA6+30GF core and 304 shell – Resists heat, corrosion and reduces replacement frequency in busy installations.
