The KAYBE SC-SC (UPC) OS2 Single Mode Duplex Fibre Optic Cable delivers dependable high-speed connectivity for 100G networks, supporting CWDM over the extended 1260–1625 nm wavelength range to maintain excellent signal integrity across long distances. Manufactured with 9/125 µm single-mode fibre, it is laser-optimized for data centers and enterprise networks while remaining backward compatible with OS1 infrastructure. Precision ceramic ferrules ensure accurate fibre alignment with insertion loss below 0.3 dB, and UPC-polished SC connectors provide improved return loss for stable transmission. The bend-insensitive fibre design minimizes attenuation in tight routing scenarios and exceeds ITU-T G652.D/G657.A1 and IEC industry standards. Encased in a Low Smoke Zero Halogen (LSZH) flame-retardant jacket, the cable emits minimal smoke and toxic fumes, making it suitable for safe installation in data centers, industrial facilities, transport systems, and residential environments.
