80/124.5µm Diameter Operating at Exceed 980nm Coupled single-mode fiber

Coupled single-mode optical fiber is a specialized single-mode fiber designed and developed specifically for optical device applications. This series of fiber preforms utilizes an in-tube chemical vapor deposition process. Combined with a well-designed waveguide design, the fibers exhibit low hydroxyl content, excellent bend resistance, and superior optical uniformity. A double-layer UVcurable acrylate coating imparts high tensile strength and long-term fatigue resistance. These fibers are widely used in optical fiber communications and sensor devices.
