Covers the number of possibly primary failures occurring in the optical fibre cable in a specified installation to within values which are lower than or equal to the limit value, defined as the tolerable frequency of primary failures. Also gives the method for calculating the possible number of primary failures, choosing the feasible protective measures and indicating the tolerable frequency of primary failures.
