Ethernet First Mile (EFM) provides high capacity connectivity based on bonding multiple copper pairs to deliver higher bandwidths.
EFM is an attractive option when sites need better connectivity than standard ADSL or SDSL broadband, but cannot justify the investment required for a Fibre Ethernet Service. EFM bridges the gap between ADSL and Fibre Ethernet, and is often suited to medium traffic sites that still require high availability and high quality. One of the major advantages with EFM is that if a fault occurs on a single pair, the connection will continue to be available, albeit at a lower speed.
There are two primary scenarios where customers choose EFM:
- As access for a national network - use of 2 & 4 pair EFM to backhaul data onto our MPLS network. Updata offers symmetrical bandwidths up to 16mb with a maximum distance of 4km between serving exchange and customer site. Our network enhancement roadmap includes up to 8 pairs, which will increase both the distance and support symmetrical bandwidths up to 30mb.
- As an access for a closed regional network deployment - Updata currently supports up to 8 pair EFM, however this will soon be extended to 12 pairs, allowing us both to support distances beyond 7km and speeds in excess of 40mb.
Key Features
- Symmetrical bandwidths up to 40mb depending on deployment scenario
- Improved availability due to “elegant degradation” on failure of individual copper pairs
- Plug and play RJ45 Ethernet
- Short lead times SLA options tailored to suit both your business and financial requirements
