DurableBand™-R 180μm [LL] G.657.A1/G.652.D low loss large mode field anti-bending low water peak single-mode fiber significantly reduces attenuation in the entire wavelength range of 1260~1625nm. Durable Band™-R 180μm [LL] exceeds the requirements of ITU-T G.652.D and ITU-T G.657.A1. It is suitable for high-capacity, long-distance transmission and access networks. This fiber optic has a cross-sectional area that is only 54% of standard fibers and 80% of 200um ordinary small diameter fibers, which helps to miniaturize equipment or accommodate more fibers under the same laying conditions. While significantly reducing the coating, it maintains the same glass outer diameter and precise geometric size control as conventional fibers, ensures low splicing loss and high splicing efficiency, excellent mechanical properties and environmental characteristics ensure stable performance of optical fibers in various usage environments.
