Fiberoptictechnology — huge bandwidth (nearly 50 terabits per second (Tbps), low signal attenuation(衰減) (as low as 0.2 dB/km), low signal distortion(扭曲), low power requirement, low material usage, small space requirement, and. low cost.

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

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 carrier and day of the week. Optical systems with advent the laser and optical fiber…
