What is the Difference Between Cat6 cable 23AWG and Cat6 cable 24AWG

The choice of cables plays a pivotal role in ensuring seamless connectivity and optimal performance. Among the myriad options available, Cat6 cables stand out as a popular choice for their ability to handle high-speed data transfer. However, within the realm of Cat6 cables, there exists a subtle yet significant difference — the gauge. This article will delve into the intricacies of Cat6 cable 23AWG and Cat6 cable 24AWG, shedding light on the distinctions and helping you make an informed decision for your networking needs.

What is the importance of Cat6 cable gauge and how does it affect performance?

Cable Gauge

To understand the importance of gauge in the world, we must first understand what goes inside them. Not what components they are made of, but what they actually carry through them. In the industry, it is referred to as current flow (of electrons) that runs throughout the wire. Imagine a flow of water that runs through a pipe.  The wider the pipe is, the more water runs through it in shorter time.

How does that translate to cables? Resistance is how many electrons make it through the cable and do not evaporate. With a thinner cable, there is less flow and heat buildup, which causes the electrons to dissipate.  The wider the cable, the easier it is for the electrons to pass through it.

Cable’s gauge indicates the thickness of the conductor in which the electrons flow. A 23AWG is 0.57mm wide, while a 24AWG is 0.52mm wide. Notice the lower the gauge – the higher the thickness.

To reduce resistance and allow for a better flow of electrons the diameter of the cable’s conductor must be increased. By doing so, resistance is automatically reduced over it.

Cable Performance

Is the cable’s gauge the most important element in a cable? The answer is no. the twisting rate is as important to the cable’s performance. What may not be common knowledge is the importance of twisting rate for the performance of category cables.


24AWG with high quality copper and a very good twist rate may be able to provide the performance needed. But to assure performance and avoid taking chances, the EIA/TIA standards for Category 6 cables require 23AWG, NOT 24 AWG.

The AWG Factor

Before delving into the differences between Cat6 cable 23AWG and Cat6 cable 24AWG, it's crucial to understand the concept of American Wire Gauge (AWG). AWG is a standardized system used to denote the diameter of a wire conductor. In this system, a lower AWG number corresponds to a thicker wire. Both 23AWG and 24AWG Cat6 cables are constructed using copper wire conductors, where AWG plays a significant role in determining the cable's overall performance.

Conductor Diameter

The primary distinction between Cat6 cable 23AWG and Cat6 cable 24AWG lies in the diameter of their copper conductors. Cat6 cable 23AWG features thicker conductors compared to Cat6 cable 24AWG. This difference in conductor diameter can impact various aspects of cable performance, including signal attenuation, transmission distance, and power handling capabilities.

Signal Attenuation and Transmission Distance

Thicker conductors in Cat6 cable 23AWG result in lower signal attenuation over longer distances. This translates to better signal integrity and reduced loss of data packets during transmission. Cat6 cable 23AWG is better suited for applications where data needs to travel extended distances without compromising signal quality. On the other hand, Cat6 cable 24AWG may exhibit slightly higher signal attenuation over extended distances due to its relatively thinner conductors.

Power Handling

The conductor size also influences a cable's power handling capabilities. Thicker conductors in Cat6 23AWG enable it to handle higher power levels without significant voltage drops. This attribute makes it a suitable choice for Power over Ethernet (PoE) applications, where power is transmitted alongside data signals to power devices like IP cameras, wireless access points, and VoIP phones. While Cat6 cable 24AWG can still support PoE applications, its power handling capacity may be slightly lower compared to Cat6 cable 23AWG.

Applications and Advantages

Cat6  23AWG and Cat6 24AWG cater to different networking needs and scenarios, each with its own set of advantages.

Cat6 Cable 23AWG:

Long-Distance Installations: Cat6 cable 23AWG is ideal for networking setups that require data transmission over significant distances, such as large office spaces, industrial environments, or campus-wide networks.


PoE Applications: Its superior power handling capabilities make Cat6 23AWG a preferred choice for PoE installations, ensuring reliable power delivery to connected devices.


Future-Proofing: The enhanced signal integrity and performance of Cat6 cable 23AWG make it a future-proof solution for network upgrades and emerging technologies.

Cat6 Cable 24AWG:

Space Constraints: Cat6 cable 24AWG's slightly smaller diameter conductors make it more flexible and easier to install in tight spaces, making it suitable for residential installations or areas with limited cable routing options.


Short to Medium Distances: While still capable of supporting Gigabit Ethernet and other high-speed applications, Cat6 cable 24AWG is better suited for setups with shorter to medium transmission distances.


Cost-Effectiveness: Cat6 24AWG may offer a cost-effective solution for applications that do not require the extended distance or power handling capabilities of Cat6 23AWG.

Choosing the Right Cable

When deciding between Cat6 23AWG and Cat6 24AWG, several factors come into play. The choice depends on the specific requirements of the networking project, including distance, power needs, and available space. It's essential to carefully assess these factors and consult with professionals to ensure the selected cable type aligns with the intended application.

Performance and Efficiency

In the ever-evolving landscape of networking and data communication, the choice of cable can significantly impact the overall performance and efficiency of a system. Cat6 , known for their superior capabilities, offer two main variations: Cat6 cable 23AWG and Cat6 cable 24AWG. While both cable types adhere to the Cat6 standard, their differences in conductor diameter result in variations in signal attenuation, transmission distance, and power handling capabilities. Selecting the appropriate cable type, whether it's Cat6 cable 23AWG for long-distance and PoE applications or Cat6 24AWG for tighter spaces and shorter distances, is a crucial decision that can ultimately optimize network performance and reliability. As technology continues to advance, understanding the nuances between cable options ensures that networking solutions remain robust, adaptable, and future-ready.

So, when planning your next networking endeavor, remember the significance of the humble yet powerful cable, and make the informed choice that aligns perfectly with your connectivity needs. Whether it's Cat6 23AWG or Cat6 24AWG, the right cable can make all the difference in achieving seamless data transmission and unlocking the full potential of your network infrastructure.
