Optimal Design of Low Loss Lc Multi-core Optical Fiber Connector
Multi-core fiber with space division multiplexing is widely used in optical interconnection,and the performance of multi-core fiber connector will directly affect the application of multi-core fiber.In this paper,a new eight-core LC optical fiber connector was designed,and simulation analysis was conducted to investigate the influence of parameters such as fiber core spacing,groove width,and wavelength on the transmission performance of eight-core optical fibers.The feasibility of the designed eight-core optical fiber was verified through simulation results.Subsequently,the experimental preparation process was opti-mized,leading to the prepared eight-core optical fiber connector achieving rotational alignment accuracy within the range of±0.1°,with an average insertion loss of 0.13dB and a return loss of 56.08dB.After un-dergoing multiple repeatability and interchangeability tests the additional loss was less than 0.2dB,indica-ting stable performance of the optical fiber connector.Compared with traditional single mode fiber connec-tors,the eight-core optical fiber connector had lower loss and higher communication capacity.
