Novel optical fiber with intermittent water blocking factice filled in the core

The utility model relates to a novel optical cable which has a cable core filled with intermittent water-blocking balm. The optical cable is characterized in that the water-blocking balm filled in the cable core is intermittent. The optical cable has the advantages that not only the water permeability can reach the indicators in the product standard and the block-water performance can satisfy the operating requirements but also the use level of the water-blocking balm is reduced and the material cost of the optical cable is reduced.
