摘要
Abstract
In order to take into account both optical fiber data communication and environment perception in a narrow space,a flexural three-core optical fiber is designed and prepared for the integrated system.The fiber has a triangular core arrangement and a deeply fluorine-doped refractive index channel structure with a standard outer diameter of 125 μm.The transmission char-acteristics of the O-band(1 260～1 360 nm)are optimized,and the Brillouin gain spectrum(BGS)distribution is similar to that of the G.657.A1 optical fiber.The test results show that the average loss of the core layer is 0.58 dB/km at 1 310 nm wavelength,and the average intercore crosstalk is lower than-50 dB/km.When the minimum bending radius R=10 mm and winding 50 times,the bending loss of the optical fiber is less than 0.1 dB.关键词
