A Greenfield fiber optic network design is created without the constraints of an existing network. On the other hand, a Brownfield fiber optic network design needs to work within the constraints of an existing network. There has been a sustained effort to design Greenfield networks and get fiber in the ground to light up the end user. However, those Greenfield networks are quickly turning brown and the design tools required to prune these networks are becoming more important than ever. And the need for these tools will extend far beyond the time when the last Greenfield plows have been stored away in a shed somewhere. This seminar will use real world data to demonstrate the problems experienced by network providers when attempting to find available fibers between locations that need to be connected. It will use this data to show how a GIS system combined with innovative software can display the fibers from each cable in the network in such a way that a designer can better visualize the connectivity of fibers, like an x-ray of the network. Using this insight, the designer will be able to allocate fibers faster and more efficiently while simultaneously creating the necessary splicing instructions. The problem with the current approach to assigning fibers, even for networks that are well documented, is that the underlying fiber data is difficult to visualize. Individual splice locations can be viewed, but what is missing is the ability to holistically see all fibers in a route simultaneously. This seminar will propose an approach to correct that.
