A 4.0μm core diameter is compatible with medium-power red lasers (≤500mW), avoiding optical path damage caused by high power with small core diameters;
The Φ4×14mm specification has a waist size of 1.2mm (the largest waist size in the entire red wavelength range), making it suitable for wide-spot red laser applications;
Red light has a low air attenuation rate, and low-loss transmission ensures the stability of long-distance signals.
