Optical Fiber & Fiber Patch Cables, Single-mode Optical Fiber

Compared with other single-mode fibers, the most significant feature of G657 fiber is its insensitivity to bending, which means that the bending loss of G657 fiber is relatively small. G.657.A2 has a minimum bend radius of 7.5mm and is fully compatible with G.652 Single-mode Optical Fiber.

Characteristics

Satisfied and superior to the technical requirement of ITU-T G.657.A1/A2;
Excellent performance of Bending Resistance;
Fully compatible with G.652 single-mode fiber, full-band transmission from 1260nm to 1626nm;
Low PMD meets the needs of high-speed and long-distance transmission;
High anti-fatigue parameters ensure long life under small bending radius;

Application

Applicable to various structures of optical cables, FTTH high-speed optical routing, optical cables with small bending radius requirements, optical fiber devices, etc.
