The reason for the fiber optic cable interruption in the repeater section is

A more common cause is poor field termination that results in air gaps and high insertion loss or scratches, defects and contamination on the end face of the connector. In fact, contamination remains the leading cause of fiber failures—dust, fingerprints and other oily substances cause excessive. Fiber optic cables are the backbone of modern communications, delivering high-speed data over long distances with minimal loss. However, in real-world installations, whether underground, aerial, or in harsh industrial environments, fiber cables can and do fail. The interruption of optical cables does not necessarily lead to service interruption. With their ability to transmit data at speeds up to 1.
