Leased lines are a means of connecting to the internet via a dedicated fibre optic cable.
Unlike broadband, a leased line is fibre optic cable from the exchange all the way into the premises. Therefore as no copper cable is involved there is no electrical resistance which can slow the speed down over distance.
Typical speeds are from 30Mb to 100Mb, via a dedicated cable that is for your exclusive use and not shared with anyone else. For larger businesses, connections of 1Gb or 10Gb can also be provided. Lines come with a guaranteed uptime and service level agreement, making them the most reliable and guaranteed method of connecting businesses to the internet.
