Optical-fiber cabling continues to be deployed, and is operating reliably, in many utility-scale solar arrays all over the world. :: Martyn Easton is global marketing manager with Corning Cable Systems ().
Utilities build fiber optic networks in similar ways that others build them, aerial and underground, but they also mix aerial cables in their power distribution cables, sharing towers and poles. In order to do this, they use some very different types of cables.
Optical fiber is quickly replacing copper cable in substation automation. Fiber ofers several advantages:
With regard to fiber count, commonly 12 fibers are provisioned from the SCC to each of the PVCS sites. In the illustration, this would entail running a 48-fiber cable through the three PVCS sites, dropping 12 fibers at each and 12 fibers at the substation site. Six-fiber cables are typically run from PCS-to-PCS.
