60/80/124.5µm Diameter Operating at 1310nm/1550nm Bend-insensitive sm single-mode fiber

Bend-insensitive single-mode optical fiber features small geometry and bend insensitivity, maintaining excellent optical performance even under tight bend radii. This fiber meets the requirements of small-sized optical cables and optical devices and is widely used in industries such as fiber-optic hydrophones. This fiber can be custom-designed to meet user requirements for mode field diameter, cutoff wavelength, and bend sensitivity. This series of optical fiber preforms utilizes an in-tube chemical vapor deposition process and exhibits advantages such as low hydroxyl groups, high
numerical aperture, and excellent optical uniformity. The fiber's double-layer UV-curable acrylic resin coating, specifically designed for optical devices with small bend radii, reduces bend-induced attenuation and exhibits excellent optical performance. It also possesses high tensilestrength and long-term fatigue resistance.
