FPV drone fiber Bend Insensitive Single-Mode Optical Fiber G.657.A2
Standard
The fiber complie with or exceed the technical specifications in ITU-T G.657.A1/A2/B2.
Features
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.
ApplicationsAll 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.
