An RJ45 Inline Coupler is a simple, compact device used to join two Ethernet cables. It features two female RJ45 jacks, effectively extending the length of a network connection without the need for a switch or a single, long cable. This passive coupler is ideal for home networks, offices, and data centers for quick and easy cable extensions, maintaining a reliable wired connection. For optimal performance, especially with high-speed networks like Gigabit Ethernet, it is recommended to use a high-quality, shielded coupler to minimize signal loss and crosstalk.
USAGE: FANGBE RJ45 Coupler extender is ideal for extending ethernet connection by connecting 2 short network cables together.
FAST SPEED To 10 GIGABITE: The RJ45 connector can speed up to 10 gigabite for connecting Cat7/Cat6 ethernet cable.
SAFE And SECURE: With nickel plated contacts and easy snap-in retaining clip, the coupler ensure a secure and corrosion free connection.
COMPATIBILITY: This 8P8C female to female Ethernet coupler jack is compatible with Cat7, Cat6 Cat5e, Cat5 network.
HIGH PERFORMANCE: RJ45 inline jack coupler meets Category 6 performance in compliance with the TIA/EIA 568-C.2 standard. It is RoHS compliant.
Designed for uncompromised network performance, this RJ45 female-to-female coupler ensures 100% signal integrity with no loss or lag—a critical feature for high-speed Ethernet connections.
Precision 8P8C Pin Alignment: Each of the 8 contacts on both sides is meticulously aligned and firmly secured, eliminating signal interference or dropouts. Whether you’re transmitting data, streaming 4K video, or running online meetings, the coupler maintains consistent speed (compatible with Cat5e, Cat6, Cat6a cables) for seamless performance.
Nickel-Plated Contacts for Durability: The gold-standard nickel plating on contacts resists corrosion, oxidation, and wear—even with frequent plugging/unplugging. This not only extends the coupler’s lifespan (up to 10,000+ insertion cycles) but also ensures a low-resistance connection, further enhancing signal stability.
Secure Snap-In Retaining Clip: The built-in snap-in clip locks the coupler tightly to RJ45 plugs, preventing accidental disconnections. No more sudden network cuts during important tasks—ideal for both fixed installations and temporary setups.
Measuring just a few inches (small enough to fit comfortably in your palm), this coupler’s space-saving design makes it a flexible solution for any networking need—no bulky equipment required.
Easy to Install Anywhere: Its compact size allows installation in tight spaces: behind routers, inside cable management boxes, under desks, or even in travel bags (perfect for remote workers on the go). No tools needed—simply plug and play.
Wide Application Range:
1. Home Networking: Extend Wi-Fi router range by connecting longer Ethernet cables, or split connections for smart TVs, gaming consoles, and security cameras.
2. Home Office & Business: Ideal for small offices, co-working spaces, or conference rooms—connect printers, projectors, or desktop PCs without rearranging existing cabling.
3. Audio & Video Systems: Maintain high-fidelity signal transmission for AV equipment like soundbars, streaming devices (Netflix, YouTube TV), or home theaters—no distortion for crisp audio and smooth video.
4. Travel & Temporary Use: Lightweight and portable, it’s a must-have for travelers who need to extend hotel Ethernet cables to their laptops or travel routers.
Reliable Quality: Made of high-grade ABS plastic housing (impact-resistant and flame-retardant) and premium conductive materials, meeting international safety standards for networking products.
Universal Compatibility: Works with all standard RJ45 Ethernet cables (Cat5, Cat5e, Cat6, Cat6a) and devices—laptops, routers, switches, modems, and more.
Cost-Effective Solution: Avoid the expense of replacing long Ethernet cables; simply extend your existing cables with this coupler, saving time and money.
RJ45 inline couplers provide seamless Ethernet cable extension in server rooms, eliminating the need for re-termination. They maintain signal integrity while connecting patch panels to network switches, facilitating quick reconfigurations and minimizing network downtime during infrastructure adjustments.
These couplers efficiently extend existing CAT5e/CAT6 cables to workstations in evolving office layouts. They enable cost-effective network scalability without replacing entire cable runs, supporting smooth transitions during departmental relocations or workspace reorganizations while preserving bandwidth performance.
In manufacturing environments, inline couplers connect machinery to control networks through protective conduits. Their rugged designs withstand vibration and temperature variations, ensuring reliable connectivity for PLCs, sensors, and HMI devices across factory floor installations.
Technicians use couplers for rapid restoration of damaged Ethernet segments without replacing entire cables. This temporary or permanent solution maintains network operation while avoiding costly rewiring, particularly in hard-to-access ceiling spaces or wall conduits.
Schools and universities deploy couplers to adapt classroom technology to changing needs. They facilitate connections between permanent wall jacks and temporary media carts, interactive whiteboards, or computer lab rearrangements, supporting flexible learning environments.
For residential AV systems, couplers join Ethernet cables behind entertainment centers where exact lengths are impractical. They ensure uninterrupted high-speed connections for streaming devices, gaming consoles, and smart TVs without compromising signal quality.
A: It's a device used to connect two Ethernet cables, extending length without splicing.
