The F-SM300-SC-C-3FC Fiber Patch cord uses F-SM-300-SC-C fiber for near UV operation. This patch cord is 3 meters long with FC/UPC connectors at both ends.


Unlike conventional fibers, F-SM-300-SC has been designed with an un-doped, pure-silica core, surrounded by a depressed, fluorine-doped cladding. Without germanium (GeO2), electronic defects and consequent color centers associated with the Ge–O bond, the prime cause of photo darkening at short wavelengths, are avoided with the result that power handling capacity is increased from a few milliwatts to several watts. In fact, in SM300, the transmission-limiting mechanism is effectively shifted from photo darkening to other nonlinearities (e.g. stimulated scattering) or even thermal damage – and in both cases, these limits too are increased over those of a conventional germano-silicate fiber.

F-SM300-SC-C-3FC光纤贴片线使用F-SM-300-SC-C光纤进行近距离紫外线操作。这个贴片电线有3米长，两端有FC/UPC连接器。

与传统纤维不同的是，F-SM-300-SC被设计成一个未掺杂的纯硅芯，周围环绕着一个凹陷的、掺杂氟的包层。在没有锗(GeO2)的情况下，电子缺陷和随之产生的与g - o键(短波长的光变暗的主要原因)相关的颜色中心得以避免，从而使功率处理能力从几毫瓦增加到几瓦。事实上，在SM300中，传输限制机制有效地从光变暗转变为其他非线性(例如受激散射)，甚至是热损伤——在这两种情况下，这些限制也比传统的日耳曼硅酸盐纤维要高。
