) Complex Table 1 The coated optical fiber of the present invention may be manufactured by a conventionally known method for forming a resin coating of this type. For example, an optical fiber preform is sent to a drawing furnace, heated and melted to be drawn into an optical fiber (glass fiber), and then a reactive diluent, a polymerization initiator, and a sensitizer are added as described above using a coating device. After applying the energy ray curable resin, the coating layer is cured by irradiating the energy ray to form a coated fiber, which is then wound up while being taken off.

It was less than 10'. Assuming that the same amount of energy is irradiated, the larger the molar extinction coefficient, the more energy is absorbed and the larger the energy transfer to the photopolymerization initiator. That is, in the present invention, the molar extinction coefficient of the resin is larger than that of conventional products, and the amount of energy received by the photopolymerization initiator is increased. This allows more active species to be created with the same energy than with conventional resins.
