Research reveals that there were around 2.4 billion Internet users in 2014. By June 2019, that number doubled to 4.4 billion. That’s an 83% increase in the Internet user base in a span of just five years. For the media and telecommunications sector, this raises an all-important question: For the media and telecoms sector, how far can current underlying networks scale to accommodate the growing traffic on the Internet?

While the good news is that no one single network will need to support this burgeoning traffic, there remains some scepticism around existing networks and their ability to keep pace with the bandwidth demands of next-generation connected devices.

Businesses across various industries have already started upgrading to a networking speed of 10 gigabytes per second (GB/s). However, even 40-channel wavelength division multiplexing (WDM) systems operating on a 10 GB/s wavelength are fast reaching capacity across channels.
