KEXINT G657A1 G657A2 G652D Single-mode Multi-mode Coloring Bare Color Glass Optical Fiber
The bare fiber of optical fiber is generally divided into three layers: the center high refractive index glass core (the core diameter is generally 50 or 62.5μm), the middle is the low refractive index silica glass cladding (the diameter is generally 125μm), and the outermost is the resin coating for reinforcement.

G.652.D vs G.657.A1 vs G.657.A2
Similarity
G.652.D, G.657.A1, and G.657.A2 fiber optic cables all share the same physical dimensions, with inner and outer core diameters of 9μm and 125μm respectively. This means that cables defined by these three standards are fully compatible with each other.
Difference - Bending Radius
The diagram below illustrates the different bending radius standards for G.652.D, G.657.A1, and G.657.A2. The bending radius for G.652.D fiber is 30mm, for G.652.A1 fiber is 10mm, and for G.652.A2 fiber optic cable is 7.5mm. It is worth noting that the attenuation of G.657.A1 and G.657.A2 fiber optic cables will be slightly higher than that of G.652.D fiber. This is because when the optical fiber is bent, the path of the optical signal inside the fiber changes, resulting in increased signal loss.
Highlight
1. Ultra-High Bandwidth & Fast Transmission Speed
Bare fiber boasts unmatched bandwidth, supporting up to 100Gbps over long distances with low latency and minimal attenuation, ideal for large-data and enterprise communication.
2. Excellent Signal Stability & Anti-Interference
Unlike copper cables, it is immune to EMI, RFI and crosstalk, maintaining stable signals in harsh environments and ensuring reliable long-term operation.
3. Long-Distance Coverage & Low Attenuation
With ultra-low attenuation (0.2dB/km), it transmits signals over tens to hundreds of kilometers without frequent amplifiers,
suitable for long-haul projects.
4. High Durability & Long Service Life
Made of high-quality quartz glass, it resists corrosion, high temperature and damage, with a service life over 25 years, reducing maintenance costs.
5. Flexible Customization & Wide Application
Available in various core sizes and types (single/multi-mode), it is widely used in telecom, data centers, surveillance, etc.,
supporting flexible deployment.
