Which coating is described by '900pm coating' in the document?

A 900 μm coating describes a tight-buffered fiber. In tight-buffered cables, each individual fiber gets its own protective polymer coating with an outer diameter of about 0.9 mm, creating a sturdy, easy-to-terminate strand. This is different from loose-tube designs, where fibers sit inside larger buffer tubes and the overall diameter per fiber is not this thin, nor from gel-filled setups that use moisture-protection gel rather than focusing on the coating thickness. Armored cables add a protective armor layer around the jacket, not the 0.9 mm coating around the fiber itself.
