With the densification of data everywhere in the network (backbone, backhaul, middle-haul and fronthaul), using one fiber per service is not the best use of resources.
Multiplexing multiple services through the same fiber is more efficient in transporting data from point A to point B, while providing a sustainable and evolutive path moving forward.
Key takeaways:
Stay tuned for Part II which will cover WDM applications in 5G optical access networks.
