Ethernet First Mile



EFM is an efficient use of existing, proven infrastructure. It uses multiple bonded copper pairs to deliver an Ethernet type service direct to our customer’s premises. Using either 2 or 4 copper pairs to provide Ethernet transport, up to 20Mbps can be achieved and there are no charges for bandwidth usage.

EFM is the most cost effective way of obtaining an uncontended bandwidth over existing copper cables linked to the nearest exchange, although the data speeds will supersede any speed provided by traditional broadband services, the rate provided by EFM is still adaptive and bandwidth speeds can vary due to a number of different variants.

It is important to note that the quality of the copper wire pair and the length of the copper wire between the exchange and the premises will affect the speeds. Depending on the length of copper and the number of pairs used, EFM can provide upload speeds as fast as 18Mbps, this in comparison to standard ADSL speed of 0.7Mbps (on uploads) is a significant difference. Below is a graph which shows the indicative speeds expected, depending on the distance from the exchange.
