  • Service life standard for stranded optical cables

    Service life standard for stranded optical cables

    Most Fiber cables don't Need to be Replaced. If installed and protected correctly against technical and environmental conditions, they can last: 25–50 years (outdoor plant infrastructure, long-haul wiring) 15–30 years (indoor building wiring systems) 10–20 years (FTTH plant drop. Most Fiber cables don't Need to be Replaced. From FTTH optics to industrial applications, backbone transmission, and cloud data centers, fiber cables can last for decades under appropriate installation and handling. But ask any veteran network engineer, and they will tell you a different story. Others, installed in the 1990s, are still running. The International Electrotechnical Commission (IEC) is the leading global organization that prepares and publishes International Standards for all electrical, electronic and related technologies. Please make sure. With proper installation, fibre optic cables have a service life of around 25 years, but in practice, can perform for far longer.
