To solve a problem of deterioration in workability/efficiency and need for longer working time, in directly mounting a protective tube 20 on an optical connector at the site of connection, whereas conventional protective tubes are formed cylindrical, causing difficulty in the size and shape for the mounting, and forcing use of an adhesive, a caulking method, or the like.
The coated optical fiber protective tube is provided with an outer shape that is rectangular in cross section, comprising a long and a short side comparable to a drop optical cable and an indoor optical cable, and is provided with an inserting hole formed longitudinally, having the inside diameter larger than the outside diameter of a coated optical fiber to be inserted therein. Consequently, it makes direct mounting of a coated optical fiber possible on an optical connector that is attachable to these optical cables. Through a simple operation of inserting the protective tube onto the rear part of the optical connector, for example, the coated optical fiber can be surely protected from the end of the optical connector.
