Optical cable failure requires several days to be repaired

Optical cable failure means that the optical cable is broken. Operators have optical cable repair engineering teams. Generally, if the optical cable is broken, the break point needs to be found and repaired immediately. Just repairing an optical cable with dozens of cores will not take long. The key is that if the optical cable is broken, the breakpoint may not be found immediately, and the time required to find the breakpoint may not be long.

Normally, it can be repaired in half a day in a city, and it can be repaired in a day in the countryside.
