Countries race to develop terabit per second optical fiber networks for 5G, fiber-to-the-home (FTTH) and data center interconnect (DCI) cloud services.

Fiberoptictechnology

One of the biggest challenges for 5G and last mile 10 Gig deployments is not raw data speeds, but middle mile and core networks.  Currently, top speeds for core networks are between 200 Gbps and 400 Gbps, depending on the…...
