Bend-Insensitive Single-Mode Fiber

Bend-insensitive single-mode fiber features a small geometric size and bend insensitivity, maintaining good optical performance even under small bend radii. It meets the requirements of small-size optical cables and optical devices and is widely used in fields such as fiber optic hydrophones. The fiber can be specially designed according to customer needs to meet requirements for mode field diameter, cutoff wavelength, and bend sensitivity. The fiber preform for this series adopts an in-tube chemical vapor deposition (MCVD) process, offering advantages such as low hydroxyl content, high numerical aperture, and good optical uniformity. To meet the design requirements of optical devices with small bend radii, the fiber uses independently developed coating materials, reducing bend-induced additional attenuation and demonstrating excellent optical performance, along with high tensile strength and long-term fatigue resistance.
