北億纖通旋轉(zhuǎn)光纖主要應(yīng)用于光纖電流互感器等系統(tǒng)中關(guān)鍵的敏感器件,具有圓偏振保持能力及抗環(huán)境干擾能力。 該旋轉(zhuǎn)光纖采用高雙折射光纖預(yù)制棒,在拉絲的過(guò)程中進(jìn)行高速旋轉(zhuǎn)。這種特殊工藝制造的旋轉(zhuǎn)光纖的兩個(gè)本征模式是橢圓偏振的,其內(nèi)部故有的雙折射能夠有效的抵抗由于外界條件(如溫度,彎曲,振動(dòng)等)導(dǎo)致的雙折射,從而有效的保持圓偏振光特性。旋轉(zhuǎn)光纖不僅能夠保持圓偏振光,而且具有極為突出的抗環(huán)境干擾能力,在溫度波動(dòng)和振動(dòng)條件下都能夠確保極高的工作精度,顯現(xiàn)出比低雙折射光纖更大的優(yōu)勢(shì)。
