G.652D single-mode optical fiber with large core diameter is available from global manufacturers like GL FIBER and AIMIFIBER, suitable for deployment in Panama.

Key Specifications of G.652D Fiber

G.652D fiber, also known as low-water-peak single-mode fiber, is designed for high-speed networks and long-distance transmission. Its main features include:

• Core Diameter: Standard single-mode core of ~8–10 µm, optimized for low attenuation and high splice compatibility .
• Cladding Diameter: 125 µm ± 0.7 µm, ensuring reliable fusion splicing .
• Attenuation: ≤0.34 dB/km at 1310 nm and ≤0.20 dB/km at 1550 nm .
• Operating Wavelength: 1260–1625 nm, supporting CWDM and DWDM systems .
• Macrobending Loss: Excellent resistance, suitable for dense installations and tight routing .
• Coating: Dual-layer UV acrylate (~245 µm) for mechanical protection .
