ETERN G657A2-250μm

Product Introduction
Etern G657A2 (250μm) is a bend-insensitive, low-water-peak single-mode optical fiber designed for 1260–1625nm full-band transmission. Utilizing advanced preform manufacturing and high-temperature annealing technologies, it delivers excellent attenuation and bend resistance while remaining fully compatible with conventional G.652 fibers. Its outstanding bending performance makes it ideal for FTTH deployments under tight installation conditions. Additionally, the MFD is closely matched to G.652 fibers, ensuring low splice loss.
