Yes, fiber optic cable can break under certain conditions. Although fiber optic cables are designed to be very durable, they can still be damaged by excessive bending, crushing, or stretching.
Fiber optic cables are made up of glass or plastic fibers that are very thin and fragile, so they must be handled with care. Excessive bending, crushing, or stretching can cause the fibers to break, which can result in signal loss or complete failure of the cable.
In addition to physical damage, fiber optic cables can also be damaged by environmental factors such as temperature extremes, moisture, and exposure to chemicals. These factors can cause the cable's protective coating to degrade, which can also lead to signal loss or cable failure.
To prevent fiber optic cable from breaking, it is important to handle it carefully and avoid excessive bending, crushing, or stretching. In addition, fiber optic cables should be installed in locations where they are protected from environmental factors that can cause damage. If you suspect that a fiber optic cable has been damaged, it should be inspected and repaired or replaced as soon as possible to avoid further damage and signal loss.
