For the next generation optical transmission network, lower attenuation or larger effective area of the fibre can help the system meet 3U (Ultra high speed, Ultra large capacity, Ultra long-haul) features. Now YOFC can deliver you larger effective area and lower attenuation within one fibre: LORAYCOM.
• Larger effective area reduces nonlinear effect and enables higher signal power launched into the transmission system.
• Enable higher transmission speeds with more wavelengths over ultra long-haul distances.
• Lower attenuation level which meets the demand of extended long distance transmission
• Reduce number of repeaters and minimize CAPEX and OPEX.
• Lower bending induced loss to meet complicated deployment conditions and cable structures.
