Product Detail


G.654.E Ultra-Low Loss Large Effective Area Optical Fiber
The G.654.E is a single-mode optical fiber engineered specifically for ultra-long-haul and submarine networks. It features a large effective area and ultra-low attenuation.
This physical structure suppresses nonlinear effects like Brillouin scattering and self-phase modulation that degrade signals over extreme distances.
We manufacture this fiber to support 100G, 400G, and higher-capacity transmission systems. It maintains signal integrity across transcontinental and transoceanic links where standard fiber fails.

Core Features of Our Single Mode Bare Fiber
Ultra-Low Attenuation
Attenuation as low as ≤0.17 dB/km at 1550nm helps minimize signal loss across extended transmission spans.
Large Effective Area
A typical 125 μm² effective area at 1550nm supports higher optical power levels while reducing nonlinear signal distortion.
Controlled Dispersion & PMD
Optimized dispersion and low PMD characteristics help maintain signal quality in high-capacity transmission systems.
High Mechanical Reliability
A proof test of ≥9.0 N provides strong tensile performance for demanding long-distance fiber deployment.
