How Dark Fiber Is Reshaping Cloud Economics
In this episode of Networking Tech with Fexingo, Lucas and Luna explore the hidden economics of dark fiber — the unlit cables that form the backbone of modern cloud infrastructure. With data centers in Northern Virginia and Ashburn now competing for physical proximity, we look at how leasing dark fiber instead of buying lit services gives hyperscalers like Microsoft and Amazon a strategic edge in latency and cost control. We break down the specific financial mechanics: why a single strand of fiber costs less than you think, but the deployment complexity drives up real-world expenses. You will learn how the shift from carrier-owned middle-mile networks to direct private connections is changing the balance of power between internet service providers and cloud giants. This is not just about faster speeds; it is about who controls the physical path your data takes across the country.
