Each episode opens with a recent network outage, a peering dispute, or a routing-table anomaly — then traces the engineering decisions and business incentives behind it. Lucas maps the technical architecture (BGP, MPLS, IXPs), while Luna pushes on the economics: who pays for undersea cables, why ISPs throttle certain traffic, and how network neutrality shapes startup access. They analyze real incidents — AWS’s Tokyo region failure, a Level 3 vs. Cogent peering war, or the latency impact of a new data-center route — and explain what network engineers actually debate in NANOG meetings. This is not a ‘how the internet works’ primer; it’s the layer-3 view for professionals who manage, build, or invest in network infrastructure. Expect granular discussions of dark fiber, CDN caching strategies, and the politics of IP address allocation. By the end, you’ll see the internet as a finite, fragile, and fiercely competitive topology — and understand why a single undersea cable cut can reset stock prices. #InternetInfrastructure #NetworkEngineering…","last_synced_at":"2026-07-18T22:19:10.157593+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928"},"episode":{"title":"How Optical Transport Networks Handle 400 Gigabit Internet Backbone","slug":"how-optical-transport-networks-handle-400-gigabit-internet-backbone","published_at":"2026-07-06T22:29:22+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-optical-transport-networks-handle-400-gigabit-internet-backbone","show_page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928","url":"https://audio.fexingo.com/business/networking-tech/episode-0095.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0095.mp3","summary":"Episode 95 of Networking Tech with Fexingo dives into the engineering behind 400 Gigabit optical transport networks. Lucas and Luna explain how coherent optics, advanced modulation formats like 64QAM, and wavelength division multiplexing push single-fiber capacities past 30 terabits per second. They trace the evolution from 10G to 400G, discuss the role of the OIF 400ZR standard in hyperscaler data center interconnects, and examine real-world deployment challenges like chromatic dispersion and amplifier noise. The episode also covers how network operators are future-proofing for 800G and 1.6T using silicon photonics and machine learning-based link optimization. Perfect for network engineers, telecom professionals, and anyone curious about the physical layer that powers the global internet. #OpticalTransport #400Gigabit #CoherentOptics #DWDM #400ZR #NetworkEngineering #InternetBackbone #SiliconPhotonics #FiberOptics #DataCenterInterconnect #OIF #ModulationFormats #NetworkInfrastructure #TechPodcast #FexingoBusiness #BusinessPodcast #NetworkingTech #FutureOfNetworking Keep every episode free: buymeacoffee.com/fexingo","meta_description":"Episode 95 of Networking Tech with Fexingo dives into the engineering behind 400 Gigabit optical transport networks.
