How does wireless 5G come into relation with Fiber?

In last several months, 5G is a hot topic wide-spreading between Carriers, equipment manufacturers, industrial analysts and so on. What is it and what is its relationship with our fiber optic solution providers? Today, I read some reports, articles, posts and conclude something for your reference.

Firstly, Let’s talk about 5G:

5G, which means 5th generation mobile networks or 5th generation wireless systems, is proposed as the next generation telecommunication standard beyond the current 4G. At present, 5G deployment is at an early stage, there is no standard for it, but its key characteristics are higher capacity and lower latency. What’s more, 5G aims to fulfill that:

  • Data rates of tens of megabits per second for tens of thousands of users
  • Data rates of 100 megabits per second for metropolitan areas
  • 1 Gb per second simultaneously to many workers on the same office floor
  • Several hundreds of thousands of simultaneous connections for wireless sensors
  • Spectral efficiency significantly enhanced compared to 4G
  • Latency reduced significantly compared to LTE
  • Coverage improved
  • Signaling efficiency enhanced
Then, 5G wireless systems still need fibers?

Definitely, Yes. Even though, access to 5G networks will be wireless, but much of the rest of the infrastructure will use fiber optics. Comparing to 4G, 5G requires higher bandwidth, higher data rates, more convergence and wider coverage. Thus, it’s said that there are a huge potential for fiber optic industry in 5G market, and some suppliers of fiber optic systems are already straining at the bit to design and sell their systems into the 5G infrastructure that is beginning to be built now. Even though there exist uncertainties for 5G as the standards are unsure, it’s still considered that WDM-PON architecture has the edge in the 5G wireless backhaul space (Refer to CIR report posted in June 2017 ).

Similar to how 10Gb/s multi-rate optical modules have become the standard for LTE fronthaul, 25G devices are expected to be used in high volumes in 5G deployments. In recent years, various equipment manufacturers launch their 25G switch, such as Cisco, Mellanox, Dell, Broadcom… As a result, 25G optical transceivers are naturally in increasing needs.
