The fiber optic patch cable plays a crucial role in connecting individual fibers to network devices, facilitating the transmission of signals. These cables are designed to provide a reliable and efficient pathway for light signals to travel between various components within a fiber optic network, such as switches, routers, and other connectivity devices.

When it comes to fiber optic communication, the integrity and performance of the signal transmission can greatly depend on the quality of these connections. The patch cable ensures that data can be transmitted at high speeds over long distances without significant loss or interference. This capability is vital for maintaining the efficiency of data networks in various applications, including telecommunications, internet connections, and data centers.

In contrast, other choices refer to different functions that do not align with the primary purpose of a fiber optic patch cable. For example, powering network devices is the function of power cables or power over Ethernet systems, while signal amplification is typically handled by specific amplifier units rather than patch cables themselves. Additionally, data storage is unrelated to the function of a patch cable, which is primarily concerned with signal transmission and connection. Hence, option B accurately reflects the correct role of the fiber optic patch cable within a network.
