The F-SHB1250-7.3/125 is a Spun HiBi fiber designed to allow long lengths of fiber to be used in small diameter coils for Faraday effect current sensors. SHB fibers are fabricated by spinning a �Bow-Tie’ polarization maintaining preform during the fiber drawing process. They preserve circular polarization by design and are therefore insensitive to the thermal and/or vibration-induced signal fade/drift caused by stress-birefringence. This gives the SHB fibers superior performance over SLB fibers when used in sensor coils with a large number of loops.

We offer two ranges of spun fiber, SHB Spun High Birefringence (HiBi) fibers and SLB Spun Low Birefringence (LoBi) fibers. Both of these products are optimized for use in polarimetric sensors, including the AC and DC fiber optic Current Transformers (CT) that are now replacing conventional current transformers across a broad range of applications in electrical power generation and distribution. Standard pricing is per meter.

F-SHB1250-7.3/125是一种纺成的HiBi纤维，设计用于在小直径线圈中用于法拉第效应电流传感器。SHB纤维制造通过旋转�蝶形领结的偏振保持光纤拉丝过程中预成型。它们通过设计来保持圆极化，因此对由应力-双折射引起的热和/或振动诱导的信号衰减/漂移不敏感。这使SHB纤维优于SLB纤维，用于传感器线圈与大量循环。

我们提供两种纺纱纤维，SHB纺高双折射(HiBi)纤维和SLB纺低双折射(LoBi)纤维。这两种产品都经过了优化，可用于偏振传感器，包括交流和直流光纤电流互感器(CT)，目前正取代传统的电流互感器，广泛应用于发电和配电领域。标准价格是每米。
