Paper Abstract

Most of irradiation resistant fibers are designed to contain pure quartz fiber core to ensure good irradiation resistant performance. However, multimode (MM) fiber containing pure quartz core owns lower bandwidth because of the step index (SI) distribution. Thereby the application of it will be limited though the irradiation resistance is fine attributing to pure quartz core. To combine better irradiation resistance and higher bandwidth, a novel irradiation resistant and high bandwidth MM fiber (RMM-fiber) being of special waveguide was designed and experimental investigated via testing attenuation, bandwidth and mechanical strength before and after 60Co radiation (up to 25 Mrad(Si), 10 Mrad(Si)/s). It is indicated that the RMM-fiber owns lower irradiation induced attenuation comparing with normal MM fiber, and the bandwidth after irradiation is 403.1 MHz km @1300 nm that is much higher than SI type MM fiber. The RMM-fiber shows no reduction but a little rising on mechanical strength. Additionally, it has outstanding environmental suitability in -100°C~+125°C temperature cycling test.
