The influence of joins on the state of polarization in a polarization-maintaining single-mode fiber cable link is examined. The two practical cases of linear and circular polarization are studied. Assuming perfect fibers, two random variables are involved: the phase mismatch between eigenmodes in a fiber and the misalignment of linear birefringence axes at the joins. A statistical treatment, checked with a computer simulation, gives the law of energy transfer to the undesired state of polarization and the tolerances required in both cases to obtain a given crosstalk.
研究了接头对保偏单模光纤链路中偏振态的影响。研究了线性偏振和圆偏振这两种实际情况。假设光纤是理想的，涉及两个随机变量：光纤中本征模之间的相位失配以及接头处线性双折射轴的失准。通过计算机模拟验证的统计处理方法，给出了能量转移到不期望偏振态的规律以及在两种情况下获得给定串扰所需的容限。
