摘　　要：为了评价单模光纤延时温度稳定性,建立了基于光网络分析仪的温度稳定性试验装置,测试了纯石英芯G.654D、G.652D和小模场G.657B3三种单模光纤在-40~60℃范围内的延时变化。试验结果表明,随着光纤纤芯中掺杂量的增加,光纤延时的温度变化也随之增大,相对于未掺Ge纯石英芯G.654D光纤,掺6.91 mol%GeO_(2)浓度的小模场G.657B3光纤延时的温度不稳定性增加了近50%。In order to evaluate the temperature stability of single-mode optical fiber delay,a temperature stability testing device based on a network analyzer is set up.The delay changes of three single-mode optical fibers,namely pure silica core G.654D,G.652D,and small mode field G.657B3,are tested within the range of-40℃to 60℃.The experimental results show that as the doping amount in the fiber core increases,the temperature change of the fiber delay also increases.Compared to the pure silica core G.654D fiber without Ge doping,the delay temperature instability of the small mode field G.657B3 fiber doped with 6.91 mol%GeO_2 concentration increases by nearly 50%.
