Lumen’s Fiber Path Forward

Lumen is taking a different path forward than the other big telephone companies. The company announced a major upgrade to its long-haul fiber routes that cross the country. The company’s main fiber strategy is to beef up the intercity network with plans to add six million miles of fiber to existing fiber routes by 2026. The existing Lumen long-haul fiber network came to the company in two acquisitions. The original network came when CenturyLink bought US West, which had earlier merged with Qwest, a major builder of long-haul networks. The network was strengthened when CenturyLink purchased Level 3 Communications. The original Quest fiber is getting dated in terms of capacity and performance. Much of this fiber was built thirty and forty years ago. Lumen will be using two low-loss types of fiber from Corning. This newer fiber is far clearer than older fiber and will increase the distance between repeater points while also allowing for using the fastest 400-gigabit electronics today and faster electronics later. Lumen is also pursuing a last-mile fiber expansion. Unlike the other telcos, Lumen hasn’t been talking much about the upcoming rural grant funding. This doesn’t mean the company might not pursue those opportunities since rural fiber expansion creates monopolies. But major residential expansion does not seem to be a key part of the Lumen plan, at least compared to plans for companies like Frontier, which says it plans to pass 12 million homes with fiber.
