What happens in case of fiber break?
Fiber breaks are very rare and typically any given span of 10 km of fiber will suffer an average of less than 5 minutes of outage due to breaks in a year. If there is a fiber break, the fiber provider will specify an average repair interval. The repair interval for aerial fiber is usually much shorter than buried fiber. A normal fiber break outage for aerial is 4 hours and 6 hours or longer for buried fiber. However these are average repair intervals. With buried fiber, in particular, where there may be water and mud the repair time can be considerably longer. The fiber provider will splice fibers tube by tube or ribbon by ribbon or fiber bundle by fiber bundle, rotating between tubes or ribbons operated by the separate users of the cable, including the customer, in accordance with a priority and rotation provided for in the maintenance contract. In general, priority among users of the fiber cable affected by a cut shall be determined on a rotating restoration-by-restoration and segmen
