FCJ factory Ribbon Optical Fiber 4F G.657A2 Bend Insensitive Single-Mode Fiber For Multi-core fiber optic cable
Bend Insensitive Single-Mode Optical Fiber G.657.A2
The Ribbon Optical Fiber complie with or exceed the technical specifications in ITU-T G.657.A1/A2/B2.
- 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.
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.

The optic fiber adopts G.657 series coated optic fiber, and a tight jacket layer composed of a suitable thermoplastic material is added to the outside. It has a mechanical buffer protection effect on the coated optic fiber and is easy to strip from the light;
The optic cable adopts aramid tow or the glass yarn is used as a strengthening member, and they are evenly twisted in layers or placed longitudinally outside the optic fiber tight jacket;
The optic cable is extruded with a layer of circular polyurethane (TPU) sheath outside the strengthening member.
