5G is the buzz. Everyone involved in the large telecommunications ecosystem is developing, trialing, promising and dreaming about 5G networks. While this technology comes with great promises and applications, we seldom hear about the underlying physical network that will have to transport the data to the 5G radios. That’s right, the optical fiber network that has been installed and optimized for other applications (e.g., FTTx, Remote PHY) will now need to reach deeper with possibly more stringent requirements. What does 5G really mean for the network’s fiber foundation? What are the challenges and pitfalls to avoid? How can you make sure your fiber foundation is ready for the next generation of wireless communications?
