1. Product Application
• Fiber optic patch cords of various structures
• FTTX high-speed optical router
• Optical cables with small bending radius requirements
• Small-sized fiber optic devices and optical components
2. Product Standards
eBay®The ultra-bend-insensitive single-mode fiber is fully compatible with ITU-TG.652.D and IEC60793-2-50B.1.3 fiber standards, and its performance meets and exceeds the relevant provisions of ITU-TG.657.B3 and IEC 60793-2-50 B6.b3, thus achieving compatibility and matching with existing fiber optic networks and making it easier for customers to use and maintain.
3. Product Features
• Exceeds ITU-T G.657.B3 standard requirements, with a minimum bending radius of 5mm, and is fully compatible with G.652.D optical fiber.
• Low attenuation, meeting OESCL band communication requirements
• Can be used in various optical cables, including ribbon cables, with extremely low bending-induced loss.
Precise geometric parameters and a large mold diameter ensure low weld loss and high weld efficiency.
• High dynamic fatigue parameters ensure service life under ultra-small bending radii.
