FTTC is near as makes no difference the same price as traditional ADSL2+ broadband but can deliver speeds of up to 150MBs and 80MBs uplink with the right supplier and package choice. Essentially FTTC is the same as traditional broadband except for the fact that the POP (the telephone exchange or similar) is connected to a box on your street by a fibre cable which can then serve the whole street with VDSL which is a higher speed version of ADSL2+ allowing greater signal strength owing to the shorter distance being traversed on the traditional copper lines.
Although the service is not truly symmetrical in bandwidth each way which means it does boast far better ratios of bandwidth for upload and download. As a result remote workers dialling into your offices will not experience the standstill levels of performance when trying to use office applications and can work fairly easily and without too much pain. FTTC is also effective when using cloud-based document repositories and applications such as SalesForce or Office365 - an upload speed of 10 or 20MB is more than acceptable for an SME office of up to 30 users.
Because you are receiving ethernet over copper rather than installing a bespoke fibre cable connection there is no cost of installation that needs to be settled upfront or spread over the duration of the contract. This saves cost in installation as well as surveying and planning..
As there is no surveying or planning to be made when installing the cabling - it is there already - then the amount of lead-time for installation is substantially less. A dedicated fibre connection is usually scheduled for 90 days in the UK but EFM can be rolled out within 21 days as the system only has to be configured or installed at the exchange or ISP POP, not every inch of the way between you and them.
Due to the lightweight nature of the arrangements that need to be made in order for EFM to be installed there is a far smaller risk to be incurred on the part of the provider. As a result the term of contract is usually much shorter and more open to renegotiation or change.
