摘　　要：针对光纤制导的技术要求,作者讨论了光纤波导的芯层相对折射率差、芯直径、下凹包层、内涂层等结构参数对光纤抗弯曲性能的影响规律。通过对光纤弯曲特性的深入研究后,作者报道了采用PCVD工艺制造了专利技术的抗弯光纤,并测试了相关参数。测试结果表明,这种光纤的损耗性能要求满足作为一种制导用光纤的技术要求,同时,通过光缆设计方案的讨论,作者预测了这种光纤应用于水下航行体的可行性。To meet the technical requirements of fiber optical guidance （FOG）, the influence laws of such structural parameters as fiber optical wave guide core delta, core diameter, dent clad and inner coating on the bend loss of bend insensitive optical fiber are discussed. A bend insensitive optical fiber is manufactured by plasma chemistry vapour deposition （PCVD） process with authors＇ patent, and the relevant parameters are tested. The test result shows that the bend loss of the new optical fiber meets the requirement for FOG. Through the discussion about the optical cable design scheme, the feasibility of this optical fiber/cable application to underwater vehicles is forecasted.
