How far can you run cat6?

Wired internet connections offer faster and more reliable internet access compared to wireless networks. With a variety of Ethernet cables available on the market, it is easy to get confused about which is the most suitable for your needs. Let us look into the specifications of Cat6 cables and how far you can run Cat6.

Similar to Cat5 cables, Cat6 Ethernet LAN cables consist of four pairs of twisted and unshielded wires. With the development of the IT industry, Cat6 cables have become more prevalent in local area networks for businesses and homes. However, the distance between the hub, switch, or network router and the connected device drastically affects these cables’ network performance.

As a result, the Electronic Industries Alliance (EIA) and the Telecommunications Industry Association (TIA) have set up standard cable distance specifications to prevent the distortion of data and transmission errors. For instance, Cat6 cables have a maximum length limit of 100m. If you exceed the specified cable distance, you risk losing your signal. Likewise, you can use a switch or repeater to increase the range of your cables effectively without losing data.

What is the maximum length limit of Cat6 cables?

Both Cat5 and Cat6 cables have a maximum length limit of 328 feet (100 meters), with its reliable performance being between 90 meters, and lesser speed experienced as you reduce 5 meters of each end of the cable. It is advisable to use similar rated components or have the wires professionally installed or pre-built to enjoy its full performance. Likewise, in a 10GBASE-T, an unshielded Cat6 cable should not run over 55 meters.

Performance of a Cat6 cable

Cat 6 cables are quickly becoming the new standardized cable for Ethernet as it features backward compatibility with Cat3, Cat5, and Cat5e cable standards.  They also have more stringent crosstalk specifications with less system noise compared to Cat5 and Cat5e.

Furthermore, this cable standard has a bandwidth of up to 100 MHz as opposed to Cat5 and Cat5e’s 100MHz. It also features 8P8C modular connectors that use either T568B or T568A pin alignment. The overall performance of these cables depends on the identical termination of both of its ends.

How to extend the maximum length limit of a Cat6 cable

Sometimes, it is necessary to extend the length limit of Cat6 Ethernet cables, especially if your devices are more than 100 meters away from the network source. There are a variety of devices you can use to connect to your network for up to 10km. They include:

Method	Maximum distance	Pros
Ethernet extenders	8 kilometers	Safe and easy to use Cost-effective
Fiber media converters	60km for single-mode fiber 500 meters for multimode fiber	Safe Reasonable price Promotes optimum performance Highly immune to interferences and obstructions Easy to use
Wireless Ethernet extension	10km	Flexible and convenient for use Promotes long-range connectivity

Use of Ethernet extenders

These are devices that help network providers extend their Ethernet connections beyond the 100 meters mark. Also known as repeaters, they establish a high-speed and long-range data communication link between physically distant LAN devices. Such devices can connect multiple LAN wires for a maximum distance of 8km (5 miles).

Ethernet extenders do not function in the same way. Some of them allow connections to more than two cables, while others create a chain of wires by splicing them together on each end of the device. As a result, these products are ideal for connecting different workgroups in the same building but on different floors.  As a cost-effective alternative to complicated wiring choices, Ethernet extenders have a plug-and-play functionality, making them quite easy to install and use.

Fiber optic media converters

Compared to copper wires, fiber supports longer distances due to its ability to refract light while transmitting data, allowing data integrity and fast connection speeds void of any transmission errors. By pairing fiber media converters, you can extend your Ethernet connection by converting your Cat6 copper cable from copper to fiber and back to copper. You may also opt to use the media converters with switches that support fiber to extend your Ethernet cables.

Depending on the type of connectivity you are seeking to achieve, fiber comes in single-mode and multimode. Single-mode fiber consists of a small internal core of about 8 micrometers that enables light propagation through a single pathway. As a result, this type of fiber achieves a much faster speed than the multimode fiber for a maximum distance limit of 60km, making it ideal for cable and telephone companies.

On the other hand, multimode fiber has a 50-micrometer core that disperses light signals through multiple spatial pathways, which slows down its data transmission speeds. Nonetheless, this type of fiber offers speedy performance and is popularly used in small businesses and enterprises due to their pocket-friendly price. Multimode fibers extend Ethernet connections for an additional 500 meters.

Similarly, fiber cables are extensively immune to electromagnetic interference (EMI), ground loops, surges, and spikes, making it perfect for industrial environments. Different types of media converters are available on the market, depending on their use and configuration level. For instance, standard media converters offer a simple plug-and-play installation, while industrial media converters require professional installation and management.

Wireless Ethernet Extension

You can also use a wireless Ethernet extension by creating a wireless bridge from two wireless access points. By configuring these two access points by making one of them the source (SDS AP), and the other one the destination (SDS Client), you can extend your Cat6 cable safely.

Wireless Ethernet extenders offer wireless extension, which is convenient as it does not use any unsightly wires. Such an extension requires the networks to be unobstructed and in the line of sight to ascertain optimum performance. As a result, wireless Ethernet extension provides long-range connectivity for several miles long, making it ideal for home, industrial and enterprise environments. However, it is vital to know that wireless Ethernet extenders are quite susceptible to interference from infrastructure and adverse weather conditions.

Cellular wireless routers are another alternative to wireless Ethernet extensions. With mobile wireless routers, you can easily set up a network anywhere with cellular phone reception. As a result, you can extend your Ethernet cable using cellular networks in industrial environments, factories, traffic control, or gas/oil field drilling operations. Likewise, cellular routers get rid of any interference caused by physical obstructions or distance that you may experience when using wireless radio extensions.

Conclusion

Knowing the maximum distance limit of Cat6 cable aid in determining the performance of your network. If you want to go beyond the maximum cable distance, make sure you use the appropriate devices by connecting them correctly for optimum performance.
