低双折射光纤<br /> 低双折射光纤是一种能够长距离传输光射线并且保持光的偏振态的光纤，这意味着光纤的几何特性非常的理想，并且光轴完全一致。因为任何线性偏振的光都可以用连个正交的线性偏振模式来表示，因此理想的低双折射光纤能够以完全相同的速度传播两个正交的线性偏振模式。实际使用的光纤因为各种因素，例如，不圆度，偏芯度，微弯，弯曲等会导致光纤传播两个线性偏振模式的速度不同，从而引起相位差异。<br /> 传统的<a href="http://ofc.oecr.com" target="_blank" class="relatedlink">通信</a>光纤具有比较大的相位差，而且相位差会随着光纤的长度累加，低双折射光纤的相位差非常小，而且和光纤的长度没有线性的关系。<br /> 低双折射光纤的应用：<br /> 低双折射光纤有很多的应用，其中最重要的应用是光纤<a href="http://sensor.oecr.com" target="_blank" class="relatedlink">传感</a>器，在一个法拉第旋转传感器中，低双折射光纤圈内部通过一个导体，这样，低双折射光纤中传播的线偏振光的偏振面会随着通过导体的电流的变化产生旋转，并且成一定的函数关系。<br /> 另外在有些时候，人们需要传输并且保持线性偏振光的偏振态，通常会使用高双折射的偏振保持光纤，但是这需要准确的对轴，这种情况下，可以使用低双折射光纤，方便简单，不需要考虑对轴的因素。低双折射光纤的涂覆层的类型非常重要，我们的光纤采用了特殊的低应力涂层用来确保低双折射光纤的特性。<br /> <br /> 参数 单位 指标<br /> 光纤类型 um LB600 LB800 LB1300 LB1550
