What is Ethernet First Mile?

You’ve probably come across the term Ethernet First Mile, but what exactly is it?

Ethernet First Mile (EFM) is a popular and affordable way for businesses to get easy, dedicated connectivity that delivers fibre-like connectivity using copper cables already in place and can enable speeds up to 30Mbps – dependent on the length of copper cable needed and how many pairs are used.

With committed bandwidth and symmetrical upload and download speeds, businesses can take advantage of important business tools such as Office365 and other cloud solutions as well as perform large data transfers without worrying about capacity and speed on the network dropping.

The biggest advantages of EFM are:

  • Reduced costs as there’s no need for a leased line to the premises
  • Speed of connectivity – nearly twice as quick compared to bringing fibre in to the building
  • Widely available across the UK

Often most importantly, an EFM connection is not shared, ensuring security and benefits from greater resilience – if one copper wire pair fails the service is automatically re-routed as a fail-safe.

However, despite the pros, the technology is slowly dying as it’s based on bonded pairs of copper and increasingly Fibre-To-The-Cabinet (FTTC) and Fibre-To-The-Premises (FTTP) is more commonly used as an alternative for lower bandwidth needs.
