FAQ

1. How does your "MFD mode field matching" technology solve the coupling loss of chip waveguides?

The mode field diameter of standard single-mode fiber (approximately 9-10 μm) is much larger than that of silicon photonics or InP chip waveguides (typically only 1-3 μm), resulting in significant mode field mismatch loss when directly mated. We use special high numerical aperture (High-NA) fiber or a high-precision tapered transition process to precisely compress the output mode field (MFD) of the fiber array, achieving a perfect physical match with your chip waveguide dimensions. This technology fundamentally eliminates the mode field mismatch effect, reducing overall coupling loss (IL) to the industry limit. Each channel undergoes 100% rigorous 3D interferometry and mode field profile analysis before leaving the factory.

2. What is the operating temperature range and power consumption of this array? Can it adapt to high-density chip heat dissipation environments?

As a purely passive precision optical interface component, this product has a power consumption of 0W.
