During fiber optic cable installation, what are the two main purposes of innerduct?

The correct answer highlights the dual role of innerduct in fiber optic cable installation, which primarily focuses on expansion and protection.

Innerduct serves as a conduit within a larger cable pathway, allowing additional fiber optic cables to be installed without the need for extensive rework or new infrastructure. This means it accommodates future growth—hence the term "expansion." By using innerducts, technicians can easily insert or replace fiber cables, making the system more adaptable to changing needs.

Furthermore, innerducts provide a layer of protection for the cables they house. They safeguard the fiber optic cables from physical damage, environmental factors, and potential interference from external sources. By encasing the fiber in a protected sheath, the integrity and performance of the cables are preserved over time, which is crucial for maintaining the efficiency of data transmission.

This combination of facilitating future expansions while protecting sensitive cables underscores why innerduct is essential in fiber optic installations.
