Ethernet keystone jacks and RJ45 keystone couplers are designed to fit seamlessly into wall plates, surface mount boxes, or patch panels. If you're setting up a network in your home or office, you might find yourself wondering whether to choose Ethernet keystone jacks or RJ45 keystone couplers for your installation. This post will help clarify your options.
What is an RJ45 Keystone Coupler?
An RJ45 keystone coupler, also known as an inline coupler, serves primarily to connect two patch cables, effectively extending the length of your Ethernet cable. Various types of RJ45 couplers are available, and you can explore more in "What is An Ethernet Coupler?" These couplers come in different categories and colors to suit various applications.
What is an Ethernet Keystone Jack?
An Ethernet keystone jack is among the most common types of keystone jacks. One end is used to terminate an Ethernet cable, while the other connects to an RJ45 connector. They are designed to securely fit in place with flexible tabs.
Which Should I Choose: Keystone Coupler or Ethernet Keystone Jack?
Keystone couplers and Ethernet keystone jacks typically fit into Ethernet wall plates, mount boxes, and patch panels. Unshielded versions of both are usually categorized into types like Cat5e and Cat6, while Cat6a and Cat8 options are often shielded for improved data transmission.
Both devices facilitate the connection of two Ethernet cables, but understanding how to choose between them is essential, as they each have unique advantages and disadvantages.
Keystone Couplers
Keystone couplers are generally smaller than Ethernet keystone jacks and don’t require any special tools for installation, making them a great choice for quick setups.
Cat 6 keystone couplers (shielded/unshielded)
Pros:
- Ease of Use: Designed for simplicity, these couplers are user-friendly and ideal for beginners. Just plug in two Ethernet cables, and you have an extended connection.
- Space Optimization: Their compact size allows for efficient cable management, making them perfect for small spaces and blank patch panels in server rooms or data centers.
- Efficiency and Flexibility: Offering a fast way to connect Ethernet cables, they come in various colors for organized cable management. They’re also handy for temporary connections.
- No Special Tools Needed: Installation is straightforward, requiring no additional tools or equipment.
Cons:
- Signal Quality: Using more than three keystone couplers can lead to signal loss.
- Interference: Prolonged use of an Ethernet coupler may make the connection susceptible to external interference.
Ethernet Keystone Jacks
Ethernet keystone jacks are often preferred by professionals for their reliable Ethernet connections and are commonly found in data centers.
Cat6 ethernet keystone jacks (shielded/unshielded)
Pros:
- Professional Installation: As part of a structured cabling system, these jacks provide excellent cable organization and a polished appearance, making them suitable for permanent setups.
- Future-Proofing: They allow for easy upgrades as networking technology evolves, ensuring your system remains current.
- Stable Signal: Generally less prone to interference, keystone jacks offer a more reliable signal compared to keystone couplers.
Cons:
- Special Tools Required: Installing keystone jacks necessitates a punch-down tool and stand, which can be cumbersome for some users.
- Technical Skill Needed: The installation process can be more complex, especially for novices, increasing the likelihood of errors during termination.
How to Choose for Your Network Installation
Your choice depends on your specific requirements. If you need a quick and flexible solution for temporary setups, or wish to avoid the complexities of punching down, keystone couplers are a great option. However, for a permanent and robust Ethernet connection that ensures stable performance, Ethernet keystone jacks are the better choice.
In summary, both keystone couplers and jacks can serve your home or office network needs, but keystone jacks are particularly well-suited for structured cabling systems in environments like data centers or server rooms.
Note: Removing Keystone Couplers or Jacks
Some users have noted that tightly inserted keystone couplers and jacks can be challenging to remove. Using the right tool, such as a flat blade screwdriver, can make this task easier. Simply place the wall plate on a flat surface, press down the clip with the screwdriver, and the coupler or jack should come out with ease.
Conclusion
Ethernet couplers and keystone jacks are effective solutions for connecting Ethernet cables. Your choice will ultimately depend on your project needs and your preference for ease of installation versus long-term performance and reliability.
