Our factory specializes in manufacturing premium-grade long distance low-loss fiber solutions engineered to meet the most demanding transmission requirements, delivering consistent optical performance, outstanding durability, and full compliance with international telecom standards. Whether deployed in terrestrial trunk lines, DWDM systems, or FTTH feeder networks, this advanced fiber product delivers the signal integrity and operational efficiency that modern digital infrastructure demands.
What is Long Distance Low-Loss Fiber?
Long Distance Low-Loss Fiber is a single-mode optical fiber specifically engineered to achieve ultra-low attenuation coefficients, enabling optical signals to travel extended distances with minimal power degradation. Conforming to ITU-T G.654 and G.652 series standards, this fiber type features a large effective area core design and ultra-pure silica composition that dramatically reduces both Rayleigh scattering and absorption losses, making it the preferred choice for long-haul and submarine transmission systems worldwide.

Long Distance Low-Loss Fiber Manufacturing and Production Process
Our long distance low-loss fiber is produced in ISO 9001-certified cleanroom facilities using advanced Modified Chemical Vapor Deposition (MCVD) and Outside Vapor Deposition (OVD) processes. The preform fabrication stage employs ultra-high-purity silica raw materials with precisely controlled dopant profiles to achieve target refractive index gradients. Each fiber draw undergoes real-time diameter monitoring, coating UV-curing, and automated tension control. Every production batch is subjected to rigorous attenuation, geometry, and mechanical screening in accordance with IEC 60793 and Telcordia GR-20 quality protocols.
Long Distance Low-Loss Fiber Technical Specifications
Our low-loss fiber cable delivers an attenuation of ≤0.17 dB/km at 1550 nm and ≤0.20 dB/km at 1310 nm, with a chromatic dispersion of ≤18 ps/(nm·km) at 1550 nm. The effective area reaches up to 150 µm² for ultra-large area variants, supporting high-power DWDM transmission. Cladding diameter is 125 ±0.7 µm, coating outer diameter 245 ±5 µm, and proof test tensile strength ≥0.69 GPa. Operating temperature range spans −60°C to +85°C, with a minimum bend radius of 30 mm under full load conditions.
