The lifespan of fiber optic cables depends on many factors such as manufacturing quality, installation conditions, environmental conditions and maintenance methods. Typically, fiber optic cables have an average lifespan of 20 to 25 years, but some cables can last much longer.

However, it is important to note that the lifespan of a fiber optic cable is not only determined by the cable itself, but also by the components connected to the cable, such as transmitters and receivers. Electronic components have a shorter lifespan than fiber optic cables, so it is important to replace them periodically to ensure optimal performance.

To maximize the life of fiber optic cables, it is important to follow the manufacturer's instructions for installation, maintenance and cleaning. Fiber optic cables must be handled with care and protected from physical and environmental damage to ensure optimal performance throughout their service life.
