AI Technical Summary
Existing fiber twisting devices, when improving polarization mode dispersion (PMD), struggle to balance the protection of the fiber coating with the precise adjustment of the twisting helix angle, and are prone to causing extrusion damage to the fiber coating.
A novel fiber optic twisting device was designed, which adopts a combination structure of twisting wheel, oscillating motor and rotary motor. The rotational motion is transmitted through magnetic coupling. The fiber is embedded in the groove of the twisting wheel and is combined with bearings and elastic pads to achieve uniform twisting of the fiber and avoid coating extrusion. At the same time, the rotational speed and oscillation angle of the twisting wheel are adjusted to improve PMD.
It improves the fiber PMD, avoids damage to the fiber coating, and can precisely adjust the twisting helix angle to ensure the mechanical strength and processing quality of the fiber.
