How ROADM Technology Is Revolutionizing Optical Networks

from Networking Tech with Fexingo: Internet Infrastructure, Routing, and Network Engineering · host Fexingo

In this episode of Networking Tech with Fexingo, Lucas and Luna explore the technology behind Reconfigurable Optical Add-Drop Multiplexers (ROADMs) and how they are transforming long-haul fiber networks. They discuss how ROADMs enabled a single fiber pair to carry 400 gigabits per second across 3,000 kilometers without electronic regeneration, using a real-world deployment by a major US carrier earlier this year. The hosts explain the shift from fixed optical add-drop multiplexers to colorless, directionless, contentionless ROADMs, and how this technology underpins modern internet backbone scalability. They also touch on the role of wavelength-selective switches (WSS) and liquid crystal on silicon (LCoS) technology in making dynamic optical routing possible. Perfect for network engineers and anyone curious about the physical layer of the internet. #ROADM #OpticalNetworking #FiberOptic #WDM #DWDM #WavelengthSelectiveSwitch #LiquidCrystalOnSilicon #NetworkBackbone #CarrierNetwork #Vodafone #Corning #Lumentum #Ciena #Technology #NetworkingTech #FexingoBusiness #BusinessPodcast #Podcast Keep every episode free: buymeacoffee.com/fexingo
