摘要： Large diameter optical waveguides (cane) may stiffen as diameter increases. The minimum bend radius may become larger than is practical for many applications. Standard-sized optical fibers may be fusion spliced to the ends of a cane segment where the fusion splice area is protected with a high temperature coating such as polyimide. The cane segment is then heated (e.g., using a hot flame torch or arc) and bent to form a U-bend, or other angle, that is free of bending stress. The heated glass may be shaped, while maintaining the waveguide properties of the cane. Once cooled, the cane maintains the new shape. Therefore, light may be propagated around the bend or angle. Thus, many configurations of cane devices may be fabricated. Some examples of cane configurations include coils, U-turns (U-bends), angled inputs/outputs, etc. Bent cane may be useful for loop-back operations, such as double-ended Raman distributed temperate sensing (DTS).
摘要翻译：随着直径的增加，大直径光波导（甘蔗）可能变硬。对于许多应用来说，最小弯曲半径可能变得比实际更大。标准尺寸的光纤可以通过聚酰亚胺之类的高温涂层熔接到其中熔接段被保护的甘蔗段的末端。然后加热甘蔗段（例如，使用热火焰炬或电弧）并弯曲以形成没有弯曲应力的U形弯曲或其他角度。加热的玻璃可以成形，同时保持甘蔗的波导特性。一旦冷却，甘蔗保持新的形状。因此，光可以在弯曲或角度周围传播。因此，可以制造甘蔗装置的许多构造。甘蔗配置的一些示例包括线圈，U形弯曲（U形弯曲），角度输入/输出等。弯曲手杖可用于环回操作，如双端拉曼分布式温度感应（DTS）。
