Radiation Resistant Fiber

Radiation resistant single-mode and multi mode optical fibers have been developed. In general, attenuation of silica-based optical fiber increases in high radiation environments. However new radiation resistant optical fibers have radiation resistant and attenuation recovery characteristics, which are far superior to conventional pure silica core fiber.
Figure 1 shows the attenuation of radiation resistant single-mode fiber as a function of accumulated radiation dose. It shows that attenuation of new fiber is excellent radiation resistant characteristics. Table 1 and table 2 show the specification of the fibers.
