    双孔光纤/twin-hole fiber/side-hole fiber


    Twin-hole fiber has two symmetrical side holes on both sides of the core, so it is also called side-hole fiber. Side-hole fiber is Mainly used for distributed pressure sensing. When the fiber is stressed, the core exhibits a difference in stress in the X and Y axes, resulting in localized birefringence. Accurate pressure measurements can…
