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 Passive Optical LANs Cut Building Network Costs","slug":"how-passive-optical-lans-cut-building-network-costs","published_at":"2026-06-19T09:32:20+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-passive-optical-lans-cut-building-network-costs","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-0060.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0060.mp3","summary":"Episode 60 of Networking Tech with Fexingo dives into Passive Optical LAN (POL) — a fiber-to-the-desk architecture that replaces traditional copper Ethernet in large buildings. Lucas explains how a single fiber strand from an Optical Line Terminal (OLT) can serve up to 128 endpoints via passive splitters, slashing cabling and power costs. He cites a real case: a 500,000-square-foot hospital that saved over 40 percent on installation and 60 percent on energy by switching from Cat6 to a GPON-based POL. Luna raises the elephant in the room — active Ethernet equipment is cheap now, so why switch? Lucas walks through the total-cost-of-ownership math, including reduced cooling, maintenance, and switch-replacement cycles. They also touch on the signal-loss budget, split ratios, and how POL handles Power over Ethernet (PoE) for security cameras and Wi-Fi access points. The verdict: POL is overkill for small offices but a no-brainer for campuses, hospitals, hotels, and multi-tenant buildings.
