The reliability concerns and installation challenges associated with fiber optic cable are potential downsides to its use. While fiber optic cable is known for its high bandwidth and fast data transfer rates, it is also susceptible to damage from environmental factors such as extreme temperatures, moisture, and physical stress. In addition to these reliability concerns, the installation of fiber optic cables can be a complex process that requires specialized expertise and equipment. This can result in higher costs compared to traditional copper wire installations. However, despite these challenges, the benefits of using fiber optic cable for telecommunications make it a viable option for many companies looking to improve their network infrastructure.
