在Polymicro Technologies成功完成了一项旨在证明针对深紫外操作优化的高-OH合成熔融石英阶跃折射率多模光纤（指定为FDP）的长期传输稳定性的工作。该开发在214和265 nm吸收带的长期稳定性方面取得了显着改善，这些吸收带通常与熔融石英中的日晒效应相关。这些改进适用于67至100µm的光纤芯尺寸，这是医疗和光谱学中使用的束应用的常见尺寸范围。沿着测试方案描述，提供了暴露至少70小时的光纤紫外线降解测量结果。
An effort to demonstrate long term transmission stability in a high –OH synthetic fused silica step index multimode optical fiber optimized for Deep-UV operation, designated as FDP, was successfully completed at Polymicro Technologies. The development achieved significant improvement in long term stability for the 214 and 265nm absorption bands typically associated with solarization effects in fused silica. The improvements were applied to fiber core sizes from 67 to 100µm, a common size range for bundle applications used in medical and spectroscopy. Results of UV degradation measurements for the fiber with minimum 70 hour exposures are presented along with a description of the test protocols.
