FutureGuide®-Ace ITU-T G.652.D (+ Reduced Attenuation and Bend Insensitive Complying with ITU-T G.657.A1)

Recent trends in optical fiber networks demand optical fibers having reduced attenuation to help long distance transmission and bend insensitiveness for harsh installation conditions. FutureGuide®-Ace is an enhanced fiber categorized as ITU-T G.652.D from Fujikura. It offers zero(low)-water peak attribute that enables all-band transmission and superior reduced-attenuation characteristics, while converging bend insensitiveness complying with ITU-T G.657.A1. Also the fiber ensures backward compatibility with all existing conventional networks based on G.652 fibers. FutureGuide®-Ace helps cable manufacturers to design cost-effective and aggressive higher fiber-count cable designs that assist telecom operators to plan for higher fiber density installations. Furthermore, reduced attenuation characteristics ensure longer transmission distance with less number of amplifiers and thus contributes to the reduction of total cost. FutureGuide®-Ace is suitable from long-haul to access networks of 40Gbps, 100Gbps and beyond.
