Durable Band™-R200μm G.652.D/G.657.A1 large mode field anti-bending low water peak single-mode fiber is applied in 1260-1625nm all band transmission systems. It has low loss at 1383nm and fully utilizes E-band transmission. Durable Band™-R200 μm 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 network. 200 μm coating diameter effectively reduces the size and weight of optical cables, making it suitable for miniaturized optical cables such as air blown micro cables. 9.2 micron mode field diameter (MFD) ensures low splicing loss and high splicing efficiency, excellent mechanical properties and environmental characteristics ensure stable performance of optical fibers in various usage environments.
