Optical Fiber, Spun HiBi, 1310 nm, 0.13-0.17 NA, 4.8mm Spin Pitch

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.
This bare fiber does not include a protective fiber jacket. Standard pricing is per meter. The following volume discount schedule is applied when ordering continuous lengths of optical fiber: 10 - 49 m: 15%, 50 - 99 m: 22%, 100 - 499 m: 25%, and ≥ 500 m: 28%.
