The F-SPV-C-3FC Bow Tie PM (Polarization Maintaining) Fiber Patch cord uses F-SFP fiber for 633 nm operation. This patch cord is 1 meter long with FC/UPC connectors at both ends. The slow axis is aligned to the connector key within +/- 1°.

The F-SPV Polarization Maintaining Fiber uses Fibercore's Bow-tie polarization maintaining (PM) fiber technology. This highly birefringent (HiBi) fiber has a beat-length of less than 2 mm. The beat-length, the length over which the fiber polarization rotates through 360°, is one of the fundamental performance measures: the shorter the beat-length, the better the polarization-preserving properties of the fiber. This Polarization Maintaining fiber has a 125 μm cladding, 245 μm coating, a 3.2 μm Mode Field Diameter, and a 0.14 to 0.18 NA.

F-SPV-C-3FC蝶形领结PM(保偏)光纤贴片线采用F-SFP光纤进行633 nm操作。这个贴片线长1米，两端有FC/UPC连接器。慢轴对齐到连接器关键在+ / - 1°。

F-SPV保偏光纤采用纤芯的蝴蝶结保偏光纤技术。这种高度双折射(HiBi)纤维的拍子长度小于2毫米。beat-length,长度的光纤偏振旋转360°,基本性能的措施:beat-length越短,越保偏光纤的属性。这偏振保持光纤有一个125μm包层,245μm涂层,μm模场直径3.2,0.14到0.18 NA。
