4.4um SM HP-780 near infrared visible light communication fiber

4.4μm SM HP-780 Near Infrared Visible Light Communication Fiber

4.4μm SM HP-780 Near Infrared Visible Light Communication Fiber is a high-performance single mode optical fiber specifically engineered for transmission in the 780nm near-infrared wavelength region. Designed with a precisely controlled small core geometry and optimized refractive index profile, this fiber enables stable single-mode transmission in the visible to near-infrared spectrum where conventional telecom fibers are no longer suitable.

Unlike standard 9/125μm telecom single mode fibers optimized for 1310nm and 1550nm, HP-780 fiber is developed for short-wavelength optical applications requiring precise beam quality, stable mode propagation, and low attenuation at 780nm.

This fiber is widely used in:

• Near-infrared optical communication
• Biomedical diagnostics
• Laser beam delivery
• Spectroscopy systems
• Precision sensors
• Quantum optics
• Scientific instrumentation

The 4.4μm core design ensures stable single-mode operation at 780nm while maintaining excellent optical confinement, low bending sensitivity, and high beam quality for precision photonic applications.
