Fiber optic cables can be used for both residential and commercial purposes, but there are some differences in the installation process. Residential fiber optic installations tend to be less complex than commercial ones, as they typically require fewer connections and have shorter distances between endpoints. In contrast, commercial installations may require more sophisticated equipment and expertise due to their larger scale and longer distances. However, the basic principles of fiber optic cable installation remain the same for both types of use: a professional installer will need to determine the optimal placement for cables, ensure that connections are secure and properly terminated, and test the system thoroughly before it is put into service.
