What’s the Difference Between CAT5e, CAT6, and CAT6a?
You’ve probably heard of CAT cables, even if you're not exactly sure what they do. These network cables connect devices to the internet, and CAT simply means "category." Each category represents a standardized type of twisted-pair Ethernet cable, with its capabilities determined by the technical standards it meets. These standards affect bandwidth, speed, crosstalk resistance, and overall performance.
CAT5 vs. CAT6: What’s the Difference?
CAT5 is an older type of cable, and while CAT6 provides higher bandwidth and faster data speeds, that doesn’t mean CAT5 is useless. It remains a cost-effective option for simple or low-demand networks and is often easier to install.
Notably, CAT6 cables are fully backward-compatible with CAT5 networks.
What Is CAT5e?
Released in 2001, CAT5e (“enhanced”) is an improved version of CAT5. It supports Gigabit Ethernet speeds (up to 1000 Mbps) and offers a bandwidth of 350 MHz. While it looks identical to CAT5, the improvements lie in stricter manufacturing standards and tighter wire twisting, resulting in reduced crosstalk and better overall performance.
Are CAT5e or CAT6 Cables Faster?
Below is a direct comparison:
CAT6 cables deliver about twice the performance of CAT5e and are now commonly required in new installations due to their higher standard.
Is CAT6a Worth the Extra Cost?
CAT6a is a newer, more robust standard. Its tighter twisting and improved shielding make it suitable for dense or interference-heavy environments. CAT6a supports even higher speeds, longer performance distances, and much lower crosstalk-making it ideal for networks carrying large amounts of data or synchronized timing information.
Which Cable Should You Choose?
The ideal Ethernet cable depends on your specific application. Below is a breakdown for general networking and production-industry uses.
Basic Networking
For typical basic networking needs, CAT6 is typically more than sufficient, providing a good balance of speed and reliability.
Higher Bandwidth Networks
For higher use networks, the choice should be based on needed bandwidth and future upgrade plans. CAT6a is recommended when high performance or long-term reliability is required, especially in environments that will see increased data loads.
Which Cable Should You Use for Production / Lighting / Sound / Dante / AVB / sACN Networks?
Different production environments place different demands on network infrastructure. Here’s a quick guide on how each cable category is utilized in various production protocols:
Dante (Digital Audio Network Through Ethernet)
Dante networks are often used in live sound and broadcast applications due to their ability to handle large amounts of audio data with low latency. CAT6a is typically recommended for Dante applications, as it supports higher data rates and longer cable runs without interference, essential for maintaining audio quality across multiple channels.
AVB (Audio Video Bridging)
AVB is designed for time-sensitive audio and video data. Similar to Dante, CAT6 or CAT6a cables are preferred due to their ability to support the necessary bandwidth and low latency requirements. The choice between them will depend on the scale of the production.
2110 (AES67)
The AES67 standard for interoperability of high-performance audio over IP networks benefits from the higher bandwidth of CAT6a cables. This ensures that uncompressed audio can be transmitted across networks without degradation, making it suitable for professional broadcast environments.
Our LS Cables using the Belden 1303e Cable meets 2110 Standards.
NDI (Network Device Interface)
NDI is a protocol for video production that allows high-quality video over standard Ethernet networks. CAT6a is advisable here as well, especially in high-resolution applications, to ensure that the video quality remains intact even over longer distances.
sACN (Streaming Architecture for Control Networks)
sACN is used for lighting control networks, and while CAT5e or CAT6 may suffice for smaller setups, CAT6a is recommended for larger installations or environments where many fixtures are controlled simultaneously to prevent data loss and ensure reliable communication.

Art-Net
Art-Net is a protocol for transmitting lighting control data over IP networks. In smaller setups, CAT5e may be acceptable; however, CAT6 or CAT6a is advisable for larger installations or those requiring higher performance to ensure reliable signal transmission.
