There is a duct under the fiber optic cable
Fiber optic cable is usually (but not always) installed in an innerduct that provides mechanical protection for the fiber optic cable. Generally, the duct is available in plastic, concrete, steel, iron and so on. This piece examines fiber optic ducts, their varieties, installation methods, and the technological progress influencing their development. In this article, we will discuss the importance, advantages and various areas of use of fiber optic cable ducts. Underground cables are pulled in conduit that is buried underground, usually 1-1.
