Bend-Insensitive Single-Mode Fiber

The bend-insensitive single-mode fiber features small geometric dimensions and excellent bend insensitivity. It maintains good optical performance even under small bending radii, meeting the requirements for compact optical cables and miniature optical components. It is widely used in industries such as fiber optic hydrophones. The fiber can be specially designed according to customer needs to meet specific requirements for mode field diameter, cutoff wavelength, and bending sensitivity. The preforms for this fiber series are manufactured using an inside-tube chemical vapor deposition (ICVD) process, offering advantages such as low hydroxyl content, high numerical aperture, and excellent optical uniformity. To meet the design requirements of optical devices with small bending radii, the fiber employs a proprietary coating material that reduces bending-induced additional attenuation. It exhibits outstanding optical performance, high tensile strength, and long-term fatigue resistance.
