Radiation Resistant Single-mode Fibre (RRF)

Radiation Resistant Single-mode Fibre is comprehensively optimized at the operating wavelength. At the wavelength, low dispersion, low loss and superior radiation-resistant property could be achieved. With these features, Radiation Resistant Singlemode Fibre has excellent properties of optical transmission under radiation.YOFC fibre is manufactured through the high precision Plasma Chemical Vapor Deposition (PCVD) process which makes fibre with precise refractive index profile, material uniformity and dimension tolerance, and low attenuation. Dual-layer, UVcured Acrylate coating, which has superior ability to protect the optical fibre, is designed for tight buffering optical cable that is much more stringent. It can show excellent performance in tight buffering structure, which equips the fibre with low microbending induced loss. This coating is easy to be stripped without residues in different environment. In order to improve the adaptability to the harsh environment, nd is more superior and steady.
