EFM (Ethernet First Mile)

With the increased availability and reducing price of optic fibre, EFM (Ethernet First Mile) is less common than it was a few years ago. EFM runs over traditional copper cables but in effect bonds a number of lines together to provide a synchronous, uncontended service, typically up to around 30Mbps. It requires special equipment in the telephone exchange and at the client end so is only available in certain exchanges – mainly large cities. Cost wise it is cheaper than optic fibre, however, for short term needs a WISP/Wireless Point-to-Point Link may be a more cost-effective option.
