Spectrum Enterprise, a unit of Charter Communications focuses on the large business services segment, said it will invest more than $1 billion in 2018 to increase the density of its national fiber network.  

Charter said this will be the second straight year in which the company has invested in excess of $1 billion exclusively in Spectrum Enterprise, which will be looking to expand on a network of nearly 200,000 fiber-lit buildings.  

Spectrum Enterprise will absorb the bulk of the upfront costs of fiber construction for most new enterprise clients in its footprint for solutions such as Fiber Internet Access, Ethernet and voice trunks (SIP/PRI).  

The investment will also come to add fiber density as wired networks become a significant backhaul channel for a coming wave of 5G-based services and other bandwidth-intensive offerings.
