While fiber optic lines might be,short-term upgrades to existing telecom infrastructure may be more cost-effective in limited use-cases. The more modern G.fast DSL standard, conceived in 2010 and presented to the market in 2014,is designed to enhance existing copper infrastructure. On distances less than 500 meters (1/3 of a mile), G.fast technology allows for end-users to experience gigabit speeds over a traditional copper line. This is a perfect solution for companies that are rolling out fiber optic lines between drops, but need a cost-effective solution to reduce the bottlenecking on “last mile” lines.The majority of MSO’s in the United States have installed fiber optic lines within their data infrastructure, relying on coaxial cable or copper lines for the last mile, or connectivity within neighborhoods. It makes sense. Fiber optic lines represent a significant investment If there’s a way to extend the serviceable life of current installations, the savings for a large operator would be in the millions of dollars. In developing markets, it makes sense to leverage lower-cost networks to reach more people.
