标准光模块
偏振保持光纤
Description
产品描述
保偏光纤采用发明专利技术制备而成，具备从保偏芯棒、硼应力棒、母棒钻孔一次成型的整套专有技术。保偏光纤产品是专为光纤陀螺（FOGs）和偏振敏感器件设计的特种光纤,采用熊猫型结构（Panda），其包含完美而对称的“双圆形”应力单元，纤芯与猫眼中心三点一线，为高偏振串音提供了可靠性技术保障；同时，自行设计并制备的全合成深掺杂硼棒，可以灵活设计并制备不同拍长的保偏光纤。
产品特点
● 优良的偏振串音性能(Good performance of crosstalk)
● 低衰减性能(Low attenuation)
● 优良的全温偏振串音性能（－50℃～85℃）(Wide operation temperature)
● 灵活的拍长设计(customized beat length)
● 几何尺寸一致性好(perfect Geometry)
● 易于熔接，熔接损耗低(Easy to splice)
● 端面研磨可靠性高(stable fiber end for fiber jumper process)
