The lifetime of a passive telecommunications network is of the order of a human life. The term “network life” here refers to the so-called “operational” period, i.e. everything that happens after commissioning.
Indeed, throughout its lifespan, a fiber optic network will undergo changes related to its extensions, its evolutions as well as to its environment:
Connections of new customers having a more or less pronounced impact on the existing network
Extensions due to new geographical coverage needs (creation of a new residential area), an increase in the number of users at a specific point (creation of a building instead of a pavilion) or new uses.
Diversion of infrastructures (displacement of ducts during road widening, or passage from above ground to underground during landfill operations)
Replacement of components that have become obsolete due to aging or technological developments.
