Which type of fiber optic cable is designed specifically for indoor use with a simple structure?

The fiber optic cable designed specifically for indoor use with a simple structure is the patch cord. Patch cords are typically used for short distances, connecting devices like switches, routers, or optical distribution frames (ODFs) within a building. Their simple design allows for easy installation and portability, making them ideal for indoor applications. The construction usually involves a single fiber core within a protective jacket, which simplifies handling and management.

While breakout cable and loose tube cable serve specific uses in fiber optic networks, they are generally more complex in structure and designed for varying environments, including outdoor applications. Simplex cable, although it also has a straightforward design by containing a single fiber, is less commonly used specifically in patching configurations compared to patch cords. Understanding these distinctions helps clarify why patch cords are acknowledged for their intended indoor use and simplicity in structure.
