Much controversy around FibreLAN solutions Vs copper solutions makes it difficult to reach any sort of middle ground between the two.

This free guide from AFC Group discusses the benefits of adopting GPON (Gigabit Passive Optical Network) for mining, and the comparisons between FibreLAN solutions over traditional copper solutions.
