Dark fiber: concept, pros, cons, challenges and monitoring
There is a very interesting alternative in the market in terms of communications services; we refer to the possibility of leasing or buying dark fiber segments.
Since the 90s of the last century, many companies have been making large investments in laying fiber optic cabling, managing to cover large geographic areas. Continue reading “Let’s talk about dark fiber”
Have you ever heard about dark fiber? Traditionally, the term refers to a dark or unused network infrastructure. In fiber optic networks, when data is being transmitted, light is passed through the cables. If no data is being transported, there are no light waves traveling along the cable, therefore the fiber is dark. Simple, isn’t it?
In the beginning, many companies had the tendency to future-proof their fiber optic networks by installing more cabling than what was actually needed for their current requirements, just to be prepared in case they will face an exponential data growth. Because of this overestimation and some technological developments concerning the way data is being packed, many fiber optic networks are not used at their fullest capacities. Therefore, dark fibers were created to take advantage of this extra capacity.
