Where to install aerial fiber optic cables
Aerial fiber installation places optical cable on poles or other supports rather than underground or in conduit. All-Dielectric Self Supporting (ADSS) cables can be erected in close proximity to power transmission lines. This of course, allows for pole sharing, which of course, reduces installation costs and speeds-up deployment. If we want to install the fiber optic cable on a path that already has support and don't have to worry about the span of the fiber optic cable. An aerial cable is an insulated cable usually containing all fibres required for a telecommunication line, which is suspended between utility poles or electricity pylons. -

Dispersion Dominance in Multimode Fibers
Abstract – Intersymbol interference (ISI) due to modal dispersion is the dominant limitation to the bit rate-distance product in multimode fiber-optic communication systems. If the light launched into the fiber excites only the desired principal modes, modal dispersion can be eliminated. We revise the formalism used by this method and quantify measurement errors due to receiver thermal noise. By selectively exciting 45 modes across 9 mode groups, we observed a maximum differential group delay (between mode group 9 and mode group 1) of 1.
