Will 5G replace fiber-optic network?

  • 2020-04-16

At the beginning of April, I was shocked by a news that some people linked Covid-19 to 5G network, and destroyed the towers. One simply suggests that 5G networks cause Covid-19, or symptoms of the infection. Another more insidious one is that 5G networks emit radiation that weakens the immune system, making people more susceptible to infection.

Eventually it turns out that these theories are completely wrong, studies haven't found a link between radio frequency signals and disease. Radio waves can't create a virus or spread it.

The coronavirus is a type of virus that's spread from person-to-person contact. So please must protect yourselves well when going out, wear masks and keep a safe distance with other people!

Now let's talk about what is 5G Network and its connection with fiber-optic network.

5G is the fifth generation wireless networkthat is expected to enable a wave of technologies that will change the way that people live and work. It has faster speeds, higher bandwidth and lower lag time than 4G. The data rate could reach 10Gbps, even 20Gbps.

Fiber optic networks are a type of high-speed wireline network offering improved speed, security and bandwidth over copper systems. It has long been used in long-haul networks due to its high performance over long distances — fiber can travel as far as 40 miles without losing signal strength. And the current optical fiber transmission technology is very mature, its fastest speed can reach 73.7Tbps(1T=1000G).

In an ideal world, every phone, smart sensor and mobile device could be directly connected to the fiber backbone — but that would limit the mobility of the devices. That's where 5G wireless network technology comes in. 5G networks will essentially be designed to bridge the short distance between a mobile device (as in 5G mobile services) or business (as in 5G fixed broadband) and the fiber backbone.

So will 5G replace optical fiber, we don't need optical fiber anymore? Of course not.

1. 5G signals run over new radio frequencies, it is susceptible to interference, less stable than optical fiber;

2. 5G network data transmission still depends on the optical fiber network, because optical fiber transmission is the foundation of the 5G network.

Rather, 5G wireless networks and fiber optic networks complement each other, together offering a more cohesive internet experience across fixed and mobile applications than either could alone. It's still very important to build high speed optical fiber network.
