4 Ways to Extend Copper Ethernet Beyond 100m

by | Jul 22, 2025 | News

The standard Ethernet cable length limit is just 100 metres, which can be restrictive for many network installations. Fortunately, there are several proven ways to extend Ethernet beyond these limits, each suited to different scenarios, distances, and budgets.

1. Ethernet Repeaters (Copper)

Ethernet repeaters regenerate signals to extend copper cable runs beyond 100 m. They’re cost-effective for short to medium distances but have practical limitations, as each repeater adds latency.

Recommended Product:

  • Enable-IT 828: Supports 1 Gbps throughput, extending Ethernet up to 600 m (2,000 ft) over standard copper cables

2. Ethernet Extenders over Copper

Ethernet extenders use existing copper infrastructure (like telephone wires or coaxial cables) to significantly extend your network’s reach. They are convenient and cost-effective, avoiding costly new cable installations.

Recommended Products:

  • Enable-IT 865X PRO: Delivers 1.2 Gbps Ethernet connectivity up to 1 km (3,028 ft) using standard RJ-45 copper cables.
  • Enable-IT 865XC PRO: Provides 1.5 Gbps throughput over existing coaxial cable infrastructure up to 1 km (3,028 ft).

3. Power over Ethernet (PoE) Extenders

PoE extenders provide both data and power over long distances, perfect for IP cameras, wireless access points, and other remote PoE-powered devices. This eliminates separate power wiring.

Recommended Products:

  • Enable-IT 821P: Offers reliable 100Mbps PoE extension up to 1 km (3,028 ft) over standard copper pairs.
  • Enable-IT 865Q PRO: Ideal for demanding installations, supporting up to 1.2 Gbps with 150W PoE over 1 km.

4. Outdoor Ethernet and PoE Extenders

Specifically designed for harsh outdoor environments, these extenders are ruggedized for weather resistance, ensuring reliable connectivity in outdoor or industrial settings.

Recommended Products:

  • Enable-IT 821WP: Reliable outdoor-rated solution delivering 100Mbps PoE over copper to distances up to 1 km.
  • Enable-IT 865XW PRO: High-performance outdoor extender providing 1.2 Gbps over multiple pairs at extended distances.

Final Recommendations

Selecting the right Ethernet extension solution depends on your distance requirements, existing infrastructure, environment, and budget. For shorter to medium-length extensions, copper-based extenders like the Enable-IT 865X PRO offer excellent reliability and simplicity. For longer distances or challenging environments, fibre optic or ruggedized outdoor extenders like the Enable-IT 865XW PRO will deliver stable, high-speed performance.
