Tight-buffered fiber is the basic element of various indoor cables. Because of different buffer materials, the relevant indoor cables made out of tight-buffered fibers can meet different mechanical and environmental requirements, for example, large tensile (crush), high or low temperature, frequent bends, low smoke, no corrosive, environmental, field use, distribution cabinet (frame) and other generic use, etc.
