HUACHENG Single-Mode Optical Fiber G.657.A1 Bending Insensitive Series

The Single-Mode Optical Fiber G.657 Bending Series is a high-performance product designed for high-bend environments, compliant with ITU-T G.657 and IEC standards. It features excellent bending resistance, effectively reducing additional attenuation when the fiber is bent at small radii, and is widely used in high-density wiring scenarios such as Fiber-to-the-Home (FTTH) and data centers.

Characteristics

Ultra-low macrobend loss at small radii, ideal for high-density wiring.
Stable performance at key wavelengths for efficient transmission.
Seamless integration with existing G.652.D networks.
Passes hydrogen aging tests for consistent performance in harsh environments.
Suited for FTTH, data centers, and building cabling.
