Low loss zero water peak single mode Optical fiber LL-G.652.D
Performance Highlights
Attenuation coefficients for wavelengths are available in two options: 1550 nm ≤ 0.185 dB/km (1550 nm ≤ 0.180 dB/km), 1310 nm ≤ 0.330 dB/km (1310 nm ≤ 0.320 dB/km);
Accurate Mode Field Diameter (MFD) characteristics to guarantee low fusion loss and good compatibility.
Application Scenarios
100G and B100G high‐speed long‐haul, long‐span backbone networks;
Large bandwidth metro and access networks.
