Description
Type
Bend Insensitive Single-mode Optical Fiber (G.657.A1)
Standard
The fiber complie with or exceed the technical specifications in ITU-T G.657.D /A1.
Features
- Superior anti-bending property;
- Fully compatible with G.652 single-mode fiber. Full band (1260~1626 nm) transmission;
- Low PMD for high bit-rate and long distance transmission. Extremely low micro-bending attenuation, applicable for all optical cable types including ribbons;
- High anti-fatigue parameter ensures service life under small bending radius.
Application
All cable constructions, 1260~1626nm full band transmission, FTTH high speed optical routing, optical cable in small bend radius, small-size optical fiber cable and device, L-band.
