26 AWG (26 American Wire Gauge) and 28 AWG (American Wire Gauge refers to the difference in wire gauge (thickness) of the conductors in Ethernet cables. Please see below for a comparison of 26 AWG and 28 AWG.
1. Thickness (Gauge)
• 26 AWG: Thicker conductor wires (~0.4 mm in diameter).
• 28 AWG: Thinner conductor wires (~0.32 mm in diameter).
2. Electrical Resistance
• 26 AWG: Lower resistance due to the larger diameter. This allows for better signal transmission and lower power loss over long distances.
• 28 AWG: Higher resistance, making it less efficient for longer runs.
3. Cable Size and Flexibility
• 26 AWG: Cables are slightly thicker and less flexible. Suitable for environments where durability is required (e.g., structured cabling).
• 28 AWG: Cables are thinner and more flexible, ideal for high-density installations (e.g., in data centers) where space and cable management are priorities.
4. Cable Length Limitations
• 26 AWG: Can handle standard Ethernet cable lengths (up to 100 meters for Cat5e/Cat6).
• 28 AWG: Often limited to shorter distances (typically around 15–20 meters), as thinner wires increase signal degradation.
5. Heat Dissipation
• 26 AWG: Better heat dissipation due to thicker wires, making it more suitable for applications like PoE (Power over Ethernet).
• 28 AWG: Generates more heat under higher power loads, which can be a concern for PoE usage.
6. Weight and Space
• 26 AWG: Heavier and takes up more space.
• 28 AWG: Lighter and ideal for minimizing cable bulk.
Use Cases
• 26 AWG: Best for general-purpose Ethernet cabling, long runs, and PoE applications.
• 28 AWG: Best for short-distance, high-density setups where flexibility and space savings are critical.
In conclusion, you can choose 26 AWG for longer runs, higher power requirements, or more demanding installations. You can use 28 AWG when space-saving and flexibility are more important, such as in patch panels or crowded racks.
