We initially explored a point-to-point wireless connection between the two sites but ruled out this approach due to geographic and infrastructure constraints.
On balance, we also felt that utilising a wired approach would provide a more permanent solution (e.g. wireless connections over such a long distance might suffer from future construction on the site) as well as providing significant advantages in terms of the speed of data transmission when necessary.
We outlined the approach to the Metalube team and, with their agreement, provided an armoured fibre optic cable solution joining the two points directly. Armoured fibre optics consists of a cable surrounded by a steel or aluminium jacket which is then covered with a polyethylene jacket to protect it from moisture and abrasion.
