How to Select the Best External Network Cable for Outdoor Use

With the increasing popularity of outdoor networking, choosing the right external network cable is crucial for ensuring reliable and robust connectivity in harsh outdoor environments. This article will guide you through the key factors to consider when selecting the best external network cable for your specific needs.

Considerations for Outdoor Network Cables

Durability and Environmental Resistance

Outdoor network cables must withstand the elements, including extreme temperatures, moisture, UV radiation, and physical abuse. Cables with durable jackets, such as polyethylene (PE) or polyvinyl chloride (PVC), can protect the delicate copper conductors inside. Look for cables with IP ratings, which indicate their resistance to water and dust.

Water Resistance

Since outdoor cables are exposed to rain and snow, water resistance is paramount. Cables with a water-blocking gel or tape can prevent moisture from penetrating the inner conductors. Shielded cables also provide better protection against electromagnetic interference, which can degrade signal quality in wet conditions.

Temperature Range

Extreme temperatures can damage network cables. Choose cables rated for the temperature range of your environment. For cold climates, look for cables with low-temperature flexibility to prevent cracking. In hot climates, opt for cables with high-temperature resistance to avoid overheating and melting.

UV Resistance

Ultraviolet radiation from the sun can degrade cable jackets and insulation over time. UV-resistant cables have protective coatings that absorb and reflect UV rays, extending their lifespan in outdoor conditions.

Installation Method

Consider how the cable will be installed. For underground buried installations, select cables with a direct burial rating to withstand the weight of soil and moisture. For aerial installations, choose cables with messenger wires for support.

Cable Type

Outdoor network cables come in different types:

– Unshielded Twisted Pair (UTP): Economical and suitable for short distances and low-bandwidth applications.

– Shielded Twisted Pair (STP): Provides better electromagnetic interference protection and is recommended for longer distances and higher bandwidth applications.

– Fiber Optic Cables: Offers high bandwidth and low signal loss, making them ideal for high-speed data transmission over long distances.

Additional Factors to Consider

Cable Length

Determine the required cable length and allow for some slack to accommodate any bends or curves in the installation.


Ensure the cables have the correct connectors to match your network devices. Common connector types include RJ45 (Ethernet) and fiber optic connectors (SC, LC, etc.).


A manufacturer’s warranty provides peace of mind and assurance of product quality. Look for cables with extended warranties to protect your investment.

By carefully considering these factors, you can select the best external network cable for your outdoor application, ensuring reliable connectivity and long service life in demanding environmental conditions.
