A Guide to Choosing FS Indoor and Outdoor Ethernet Cables for Seamless Connectivity

Posted on Jun 6, 2024 by

Ethernet cables, as the backbone of many network systems, play a crucial role in connecting devices and ensuring seamless communication. FS, a leading provider of networking equipment, offers a comprehensive range of high-quality indoor Ethernet cables and outdoor Ethernet cables designed to cater to diverse environments and requirements. This article explains the differences between indoor and outdoor Ethernet cables, how to choose between them based on application scenarios, and why, as a consumer, you are recommended to purchase FS bulk Ethernet cables.

Understanding Indoor and Outdoor Ethernet Cables

Before we can determine the differences between indoor and outdoor Ethernet cables, we must first have a basic understanding of both.

What Is an Indoor Ethernet Cable?

An indoor Ethernet cable connects devices within a building to a network and is intended for safe indoor environments. Commonly used in homes, offices, and schools, these cables are typically run through ducts to link PCs to the LAN network in server rooms.

What Is an Outdoor Ethernet Cable?

An outdoor Ethernet cable is designed to endure harsh conditions, with features to resist UV rays, moisture, and extreme temperatures. These cables are ideal for outdoor installations, such as connecting buildings and outdoor security cameras, where the cable is exposed to challenging environments.

What Makes Outdoor Ethernet Cable Suited for Outdoor Environment?

As their name suggests, indoor network cables are used indoors, while outdoor network cables are used outdoors. However, have you ever wondered why indoor network cables are suitable for indoor environments and outdoor network cables can be used outdoors?

The only difference between indoor and outdoor-rated cables of the same category is their outer cable jacket. It is the outer jacket that determines whether your network cable can be used in an outdoor environment.

Cable Jackets

Following are the 3 reasons why outdoor Ethernet cables are suited for outside applications:

Outdoor Ethernet Cable Is Less Likely to Crack When Exposed to Sunlight

A significant difference between indoor and outdoor Ethernet cables is their resistance to sunlight. Outdoor network cables feature UV-resistant jackets made of polyethylene (PE) or polyvinyl chloride (PVC). This UV protection prevents the cables from degrading and cracking over time due to exposure to direct sunlight, which allows you to run Ethernet cables outside. In contrast, indoor cables do not have UV protection and can deteriorate if used outdoors.

Outdoor Ethernet Cable Can Resist Moisture

Another critical difference is moisture resistance. Exterior Ethernet cables are designed to be waterproof, thanks to their low water absorption PE or PVC jackets. This feature ensures the cables can withstand rain, humidity, and submersion.

Outdoor Ethernet Cable Meets the Need for Direct Burial or Aerial Laying

Outdoor Ethernet cables are versatile and can be installed in various challenging environments. There are two specific types: direct burial cables and aerial cables.

Direct burial cables are designed to be installed underground. They are filled with a gel that blocks moisture seepage, protecting the cable's core. Aerial cables are used between poles and feature a messenger wire for added strength and stability. These cables have a low-density polyethene (LDPE) jacket that protects them from water and extreme temperatures. Indoor cables, however, are only suitable for limited types of installations.

Harsh Environments

Outdoor Ethernet Cable Is More Tolerant to Extreme Temperatures

Outdoor network cables are designed to withstand harsh weather conditions and have superior capabilities in enduring extreme temperatures compared to indoor cables. Outdoor cables are equipped to handle such situations, with operating and installation temperature ranges of -40 to 75°C (-40 to 167°F) and -20 to 60°C (-4 to 140°F) respectively. These specifications meet market standards and ensure the cables can effectively manage extreme temperature fluctuations, safeguarding your equipment to operate normally even in adverse conditions.

   Operating Temperature  Installation Temperature
 Indoor Bulk Ethernet Cable  -20 to 75°C (-4 to 167°F)  -10 to 50°C (-14 to 122°F)
 Outdoor Bulk Ethernet Cable  -40 to 75°C (-40 to 167°F)
-20 to 60°C (-4 to 140°F)

Using Tips for Indoor and Outdoor Ethernet Cables

Even if the cable is installed in conduit, you should always use an outdoor-rated version of bulk cable whenever it will be exposed to one or more of the following:

  • Sunlight

  • Humidity

  • Moisture

  • Risk of Lightning

  • Unregulated temperatures

Outdoor Cable Can Resist Harsh Environment

This is the simplest and most effective method to determine whether to use indoor or outdoor cables. Although in most cases, indoor environments typically use indoor cables and outdoor environments use outdoor cables, there are always exceptions.

For example, if the cable is protected from rain and wind but has to withstand high humidity levels or temperature fluctuations, does this situation require an indoor or outdoor cable? Opt for outdoor cables. The fact that the location is shielded from wind and moisture doesn't guarantee that the cable can withstand high humidity or significant temperature changes. Knowing this trick can help you determine when to choose indoor cables and when to choose outdoor cables.
