Product Introduction
Company low-water-peak bend-insensitive single-mode fiber combines excellent bending resistance with low water peak characteristics, enabling full O-E-S-C-L band (1260–1625 nm) transmission. The fiber ensures reliable L-band operation and easy installation, especially in FTTH networks along tight corners. Its mode field diameter matches standard G.652 fiber, achieving low splice and insertion loss, fully meeting network capacity and flexibility demands. It meets or exceeds ITU-T G.652.D/ G.657.A1/ G.657.A2/ G.657.B2 and IEC 60793-2-50 B1.3/ B6.a1/ B6.a2/ B6.b2 specifications.
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.
