Ethernet in the First Mile (EFM) refers to a situation when an operator has installed fibre optics to the cabinet (FTTC) and is able to offer an Ethernet based connection to the customer, either over fibre (EFM Fibre) or copper pairs (EFM Copper).
Whilst strictly speaking EFM Copper is not a Fibre Optic broadband service, it is referred to as such because, although the final (or first) mile of service is delivered over copper, the lion’s share of the network connectivity, either to the Internet or to other office LANs, will be over fibre optic Next Generation Networks. Consequently, many providers are marketing EFM Copper as a Fibre Optic Broadband service.
For EFM copper, there is a distance limitation of approx 3km between the user and the cabinet and the likelihood is that VDSL technologies, capable of 40mbps down and 10 mbps up, would be used to deliver service to the customer premises.
This service is very much a business service, but lower cost and quicker to install than having fibre optic cabling installed. That said, have a fibre based service and you have the ability to up to 100 mbps or even 1000 mbps, if you can afford it.
According the Metro Ethernet Forum (MEF), only 10-15% of businesses currently have access to optical fibre, so using existing copper phone lines to enable SME business customers to access the Internet at speeds of 40 mbps or, with VDSL2, 100mbps is going to be the way that business broadband is heading.
