HUACHENG Single-Mode G.654 Ultra Low Loss and Large Effective Area Fiber Series

G.654 Ultra Optical Fiber, with its excellent performance, can support current 40G and 100G systems and even meet the demands of future 400G or higher systems. Therefore, HUACHENGG.654 Ultra Optical Fiber is the best choice for long-distance terrestrial transmission and submarine cables.

Characteristics

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.
G.654 Ultra fiber complies with or exceeds the ITU-T G.654.B/E recommendation and IEC 60793-2-50 B1.2 specification.
