Product Code: Radiation Resistant Fibre

Radiation Resistant Fibre

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.
