Product Introduction
Company Low-Loss Single-Mode Fiber delivers deep optimization of attenuation across the full 1260-1625 nm operating band, achieving significantly lower loss levels at each wavelength compared to standard single-mode fiber. While retaining full-band operation capability, it further reduces attenuation specifications, making it especially suitable for carrying multi-channel high-speed services over a single fiber in scenarios demanding greater transmission distance and higher power budgets.
The Low-Loss SMF complies with or exceeds the technical specifications of ITU-T G.652.D and IEC 60793-2-50 Type B1.3 optical fiber standards.
Unique Technology
Company is a high-tech enterprise with full closed-loop capabilities from fiber winding equipment and coils to FOGs, fiber/MEMS inertial products, IMU circuits, software, and test equipment. End-to-end process control improves quality and reduces costs. Operating under ISO9001 with strict processes, it ensures product reliability and consistency.
