450nm-1750nm 125μm直径单模光纤
Fibercore’srange of specialty Single-Mode (SM) fibers are designed to offer customers thebest choice of fiber for their application without the performance sacrificesthat would be experienced by using standard telecoms fibers.
These specialty fibers are available with medium andhigh Numerical Aperture (NA) to give dramatically reduced bend losses incomparison with telecoms fibers. This allows smaller packaging sizes to beachieved, particularly useful for coiled sensors and the next generation smallform factor telecoms equipment.
The reduced cladding diameter fibers are designed toreduce static fatigue when the fiber is coiled, giving a longer mechanicallifetime in small coil diameters. Reduced cladding diameter fibers are offeredwith a high NA to benefit both from improved bend losses and improved
mechanical lifetime when coiled tightly.
Fibercore的一系列特种单模光纤旨在为客户提供最佳的光纤选择，而不会牺牲使用标准电信光纤所带来的性能牺牲。与电信光纤相比，其中一些专用光纤具有中等或者较高的数值孔径，这样的数值孔径可以大大降低光纤因为弯曲而引入的额外损耗。这使得封装尺寸更小，特别适用于线圈传感器和下一代小型电信设备。还有一些减小包层直径的光纤设计用于减少光纤盘绕时的静态疲劳，从而在较小的盘绕直径下提供更长的机械寿命。减小包层直径的光纤提供了更高的数值孔径，可以极大的降低光纤的弯曲损耗，并能够让光纤在紧密盘绕状态下拥有更长的机械寿命。
