EFM (Bonded Copper)

EFM, or ‘Ethernet in the First Mile’ is an access technology based on bonding traditional copper pairs together to provide a reliable, fast, low-latency ethernet service. EFM provides a lower cost alternative to fibre by providing connectivity between 5Mb/s and 20Mb/s, depending on the number of copper pairs used and the distance you are from the telephone exchange. The use of two or more pairs provides a level of redundancy to the EFM service so that if one pair experiences a temporary issue, the other pair will ensure the connection remains reliable.

Because most businesses will already have sufficient copper pairs on site to provide an EFM service, the lead times for providing EFM connectivity tend to be shorter than those of a managed fibre connection (typically within 30 days).
