Ethernet extenders, also known as media converters, are a popular choice among budget-conscious networking teams who seek to strike the perfect balance between technical requirements, budgetary constraints, and spatial limitations. These versatile devices are available in a broad range of sizes and offer functionalities for numerous applications.

In this comprehensive guide to Ethernet extenders, we aim to assist network designers and integrators, like yourself, in identifying the most suitable Ethernet extender for your unique network requirements. This article offers a detailed exploration of Ethernet extenders, encompassing their overview, diverse applications, guidance on selecting the right extender for your network, and access to high-performance equipment and expert design support.

Dive into the multitude of benefits and wide-ranging applications of Ethernet extenders while uncovering the process of choosing the perfect model to meet your specific needs. Continue reading to enhance your understanding of Ethernet extenders and make well-informed decisions for your network infrastructure.

Understanding the Basics and Advantages of Ethernet Extenders

Ethernet extenders, often referred to as Ethernet repeaters live up to both names. They prolong your Ethernet network's reach by amplifying or repeating the signal, allowing it to travel beyond the standard 100 m limit for Ethernet transmission over coax and UTP.

Network designers frequently opt to use multiple Ethernet extenders consecutively to connect devices. Ethernet extenders are also commonly integrated into a larger multi-port Ethernet switch node.

Ethernet extenders enable you to use basic coax cable or copper UTP instead of fiber optic cable to connect devices, even if the distance exceeds 100 m. With the appropriate device, Ethernet limits can be extended up to 3000 ft (914 m) at 10 Mbps or 2000 (610) ft at 1000 Mbps over UTP. Coaxial cable allows for even greater distances — up to 5000 ft (1524 m) at speeds of 10 Mbps.

The ability to transmit data over longer distances using coax and UTP is a significant advantage for networking teams, and it's the primary reason why Ethernet extenders are such well-liked network devices.

Applications of Ethernet Extenders

Ethernet extenders are utilized in a wide range of applications. Some of the most common include: 

  • IP video
  • High-speed computer links 
  • CCTV systems in airports, schools, offices, casinos, and other locations 
  • Ethernet speeds of 10/100 Mbps 
  • Factory automation enablement (UTP) 
  • Network retrofits to connect existing analog devices to Ethernet-based systems 
  • Security cameras and surveillance systems 
  • VDSL retrofits 
  • Transportation systems 
  • Metering systems 
  • Outdoor Wi-Fi access points

How to Choose the Ideal Ethernet Extender for Your Network

  1. Once you've determined that you need an Ethernet extender, the next step is selecting the right one for your network. This list of considerations and questions will help narrow down your search and ensure you choose a device that meets your needs.
  2. What is your bandwidth requirement? Ethernet extenders are excellent for speeds of 10 - 100 Mbps, but your bandwidth determines how far you can extend your Ethernet signal. The higher the bandwidth, the shorter the distance you can extend your network.
  3. What type of cable will you be using between extenders? You can use Ethernet extenders to transmit Ethernet over coaxial cable or UTP. Most devices are designed for one or the other, but not both. Ensure the device you select is compatible with your cabling.
  4. What’s the path length between devices? This may seem obvious, but overlooking simple aspects can lead to costly mistakes. Avoid this by understanding the distance you need to cover and choosing an Ethernet extender that can handle your requirements.
  5. What are your power requirements? Some Ethernet extenders offer pass-through power over Ethernet (POE), while others may require a separate power source. If you need POE capability, ensure it's included in the specifications for the device you choose.
  6. What kind of switch functionality do you need? Ethernet extenders are often used with Ethernet switches to ensure Ethernet traffic reaches its destination at full strength. If you're buying an extender/switch combination, consider whether you need an unmanaged switch, a self-managed switch, or one with advanced uplink management functionality.
  7. How many devices are you connecting and how many ports do you need? This will determine the size of the Ethernet extender you choose. It's crucial not to purchase one that doesn’t have enough ports for your needs.
  8. What are your operating conditions? Temperature, vibration level, humidity condensation, high-line voltage, low-line voltage, mechanical shock risk — all these factors matter and determine whether you need a standard Ethernet extender or one that’s specially hardened for tough conditions.
  9. Does your system use Unicast or Multicast transmission? How about jumbo frames? Ethernet extenders are often designed to support different transmission modes. It’s important to ensure the extender you choose supports the mode you use, especially if you use jumbo frames.
  10. Don't forget about signal protection, compatibility & installation requirements. High-quality Ethernet extenders are designed for ease of installation, compatibility with a wide range of equipment, and signal protection from power surges and other voltage transient events. It's worth taking the time to ensure you're purchasing a reliable device rather than a low-quality model.
