ITU-G.657B3 Easy bend fiber
Type:
Bend Insensitive Single-mode Optical Fiber (G.657.B3)
Standard:
The fiber complie with or exceed the technical specifications in ITU-T G.657.A1/A2/B2/B3.
Feature:
Minimum bend radius 7.5mm, superior anti-bending property;
Fully compatible with G.652 single-mode fiber. Full band (1260~1626nm) 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.
