Futong's G.654E single mode optical fiber enables customers to construct high performance optical communication networks. Compliant with international standards including ITU-T G.654.E, it has considerably low attenuation and large core area with typical effective area (Aeff) of 125 mm2, which is the best solution for ultra-long haul 100 Gb/s and beyond digital coherent DWDM systems. A dual layer acrylate coating is applied over the cladding to provide high product reliability and allows easy splicing throughout the cable life.
