In the UV resin optical fiber unit according to the present invention, the Young's modulus of the UV curable resin coating of each of the plurality of optical fiber strands is greater than the Young's modulus of the UV curable resin for filling that integrally covers the optical fiber strands. Furthermore, since a mold release agent is provided at the interface between these UV-curable resin coatings and the UV-curable resin for filling, when measuring the transmission characteristics of UV resin-type optical fiber units, etc., the UV resin coating light is Since the fiber wire and the UV resin filled in the optical fiber unit can be easily separated, the workability of the above measurement can be greatly improved.

As a result, since the UV resin-coated optical fiber wire and the optical fiber unit-filled UV resin did not stick together at the end, they could be easily separated and drawn out. Although silicone oil was used as the mold release agent in this example, in addition to silicone resin containing silicone oil, fluorine resin powder can also be used as the mold release agent.

While applying silicone oil as a mold release agent to the UV-curable resin-coated fiber with an outer layer of Kg/ mm2 ,
Optical fiber units are made by twisting galvanized steel wires around each other and coating them with UV-curable resin with a Young's modulus of 10 kg/ mm2.At low temperatures, the UV resin-coated fibers do not directly receive the shrinkage strain of the resin filling the unit. Therefore, low-temperature properties are maintained particularly well. This is because the mold release agent made of silicone oil also functions as a buffer layer. Therefore, even if a resin with a high Young's modulus is used as the resin for the unit, it can be expected that low-temperature characteristics can be maintained favorably.
