Ethernet in the First Mile (EFM)

What is EFM?

Ethernet in the First Mile (EFM) is a technology that provides high-speed and reliable internet connectivity for businesses. It involves using Ethernet technology for the local loop, which is the connection between the customer premises and the service provider’s central office. Unlike traditional broadband technologies, EFM uses Ethernet over copper pairs, making it well-suited for businesses in various locations.

Business benefits of Ethernet in the First Mile (EFM) 

High Speeds

EFM offers high-speed internet access, making it suitable for businesses with demanding data requirements, such as large file transfers, video conferencing, and data-intensive applications.


EFM is known for its reliability and stability, providing a consistent and dedicated internet connection. This is crucial for businesses that depend on a continuous and stable internet connection for their daily operations.

Symmetrical Upload and Download Speeds

Unlike some asymmetric broadband technologies, EFM typically provides symmetrical upload and download speeds. This is beneficial for businesses that require equal performance in both directions, such as those engaged in video conferencing or uploading large files to the cloud.


EFM is scalable to accommodate the growing bandwidth needs of businesses. As a business expands, it can easily upgrade its EFM connection to higher speeds without significant infrastructure changes.

Dedicated Connection

EFM provides a dedicated connection to the business premises, ensuring that the available bandwidth is not shared with other users in the same way that cable or fibre broadband might be.


EFM can be a cost-effective solution for businesses that need a reliable and high-speed internet connection but may not require the extremely high speeds provided by some fibre solutions.


EFM is versatile and can be deployed in various environments, including both urban and rural areas. Its use of existing copper infrastructure makes it a practical choice for businesses in diverse locations.

Service Level Agreements (SLAs)

Many EFM providers offer service level agreements that guarantee specific performance levels, uptime, and response times. This adds an extra layer of assurance for businesses relying on EFM for critical operations.

Ethernet in the First Mile (EFM) is a robust and versatile solution for businesses seeking high-speed, reliable, and scalable internet connectivity with symmetrical performance and dedicated connections.
