Fiber Bragg Gratings (FBGs) are one of the key enabling technologies behind the ‘DWDM Revolution’. Fibercore’s PS series of fibers have a high-germania and boron co-doped core composition, enabling high-reflectivity gratings to be written without the need to hydrogen-load. The mode field diameters of the boron co-doped fibers are engineered so gratings may be spliced into standard telecommunications, or pigtailing fiber with minimal excess loss.
The spun HiBi fiber allows highly sensitive and accurate current sensing over a wide range of environmental conditions including temperature variation and vibration, making it suitable for current transformers deployed outdoors in real-life applications. When used in conjunction with Fibercore’s PM fiber for delay lines and ZING™ for depolarizers, world-class current sensors can be achieved.
