G.654.E ultra-low loss single-mode fiber is designed for long-haul trunk lines, submarine cables and data center interconnection (DCI) applications. With pure silica core design, it achieves industry-leading attenuation performance as low as 0.179 dB/km at 1550nm, combined with large effective area to suppress non-linear effects.
Successfully completed 800G ultra-high speed transmission field trials with major carriers, this fiber is the ideal choice for next-generation provincial backbone networks, cross-country trunks and medium/long-haul submarine cable systems.
