Service life of flexible optical cable
The industry standard says Fiber Optic Cable Lifespan should last 25 years. But ask any veteran network engineer, and they will tell you a different story. Optical cables are the backbone of modern communication networks, delivering high-speed data across vast distances. Ensuring their longevity and reliability is crucial for maintaining uninterrupted service. Wireless, DOCSIS, and DSL technologies have required continuous outdoor infrastructure upgrades to increase speeds and capacity, and carriers have recognized the value of fiber as these incremental approaches typically include more optical fiber deeper into the network toward the subscriber.
