The tightly-packaged fiber is characterized in that a coating layer which is coated by ultraviolet-cured acrylic ester is adopted on the periphery of the fiber core; and a tightly-packaged outer layer formed by a tetrafluoroethylene copolymer is adopted on the periphery of the coating layer. According to a preparation process of the tightly-packaged fiber, an optical fiber core comprises a single mode and a multi-mode; the size of a single mode structure is 9/125 mu.m and the size of a multi-module structure is 50/125 mu.m or 62.5/125 mu.m; the coating layer is coated by adopting the ultraviolet-cured acrylic ester; the outside diameter of the coating layer is 250 mu.m; and the tightly-packaged layer is formed by adopting the high-temperature ethylene and ethylene-tetrafluoroethylene (ETFE) subjected to single-layer and double-layer thin wall extrusion by a high-temperature plastic extruding machine.
