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. Thus, understanding the full lifecycle of fiber optic cables is essential not only for. I typically aim for ~8-10 years. Mileage may vary depending on: Vendor support after EOL (many continue after end of sale and beyond. I get it in writing!) Supply chain constraints (some enterprise gear is still 300+ days out if ordered today!) From a hardware failure viewpoint and the “bath tube. When selecting fiber optic patch cables, consider factors such as fiber mode (single-mode vs. multi-mode), connector types (e., LC, SC, MTP/MPO), jacket material, and the environment. If installed and protected correctly against technical and environmental conditions, they can last: 25–50 years.
