Fiber Optic Switch Lifespan
Home / Fiber Optic Switch Lifespan
While routers, switches, and transceivers often have upgrade cycles of 3 to 5 years, properly installed and maintained fiber cabling systems can last 15 years or more — spanning multiple hardware generations. FAQs About Fiber Optic Product Lifecycle Management Q1: How long do fiber optic products typically last? With proper maintenance, fiber optic cables can last 20–30 years, though their performance may degrade over time due to environmental factors or wear (18). Contrary to what everyone in here is saying, I'm in the ISP business and we were always told that the expected lifespan of fiber is 30ish years. Fiber Broadband to each subscriber, by contrast, is the only communications technology that can support decades of speed and capacity increases with no upgrades to the outdoor infrastructure. The scalability of today's optical fiber to support higher speeds is virtually unlimited, to speeds 60,000.
