Imagine a high-density wiring environment where fiber optics are no longer fragile "glass threads" that require careful handling. A world where cables can be bent easily without worrying about signal attenuation—this is the dream of every network engineer. The EasyBand® G657A1 bend-insensitive single-mode fiber makes this vision a reality, offering unprecedented flexibility in network deployment while maintaining exceptional performance.
The EasyBand® G657A1 single-mode fiber is a fully optimized product designed for O-E-S-C-L band (1260-1625nm) applications. It features outstanding macro-bend resistance, maintaining low loss even with small-radius bends to ensure stable and reliable signal transmission. Additionally, its low-water-peak characteristic enhances overall fiber performance.
The EasyBand® G657A1 fiber has broad applications across nearly all fields requiring optical transmission:
