What is the role of a patch cord in a fiber optic system?

In a fiber optic system, a patch cord serves a crucial function by connecting devices to the fiber network. This component is typically a short length of fiber optic cable that features connectors on both ends, allowing for easy interconnection between network devices, such as switches, routers, or servers, and the fiber optic distribution. These connections facilitate the transmission of data in the form of light signals over long distances, ensuring that various network components can communicate efficiently.

While amplification of signals is important in certain contexts, patch cords themselves do not amplify signals; rather, they maintain the integrity of the signal as it travels from one device to another. The conversion of optical signals into electrical signals is performed by transceivers, not by patch cords. Additionally, while protecting fibers from external damage is a critical aspect of fiber optic installation, this is typically achieved through proper cable management and protective housings, rather than the patch cord itself. Thus, the primary role of a patch cord is to effectively connect devices within the fiber optic network, making option B the most accurate.
