Ethernet in the first mile (EFM) refers to using one of the Ethernet family of computer network protocols between a telecommunications company and a customer's premise. From the customer's point of view it is their "first" mile, although from the access networks' point of view it is known as the "last mile". A working group of the Institute of Electrical and Electronics Engineers (IEEE) produced the standards known as IEEE 802.3ah-2004, which were later included in the overall standard IEEE 802.3-2008. Although it often is used for businesses, it can also be known as Ethernet to the Home (ETTH). One family of standards known as EPON uses a passive optical network.

Famous quotes containing the word mile:
“It was a tangled and perplexing thicket, through which we stumbled and threaded our way, and when we had finished a mile of it, our starting-point seemed far away. We were glad that we had not got to walk to Bangor along the banks of this river, which would be a journey of more than a hundred miles. Think of the denseness of the forest, the fallen trees and rocks, the windings of the river, the streams emptying in, and the frequent swamps to be crossed. It made you shudder.”
—Henry David Thoreau (1817–1862)
