ABSTRACT:
The present invention relates to an optical fiber unit for air blown installation, which includes at least one optical fiber; a buffer layer surrounding the optical fiber and made of radiation curing acrylate; an outer layer surrounding the buffer layer and made of radiation curing acrylate; and a group of solid particles attached to a surface of the outer layer and having an average diameter of 80 to 140 μm and a specific weight of 2 to 3 g/cc. Thus, there is provided a structurally stable optical fiber unit, which allows easy control of particles while the optical fiber unit is produced, and also has improved installation properties.
