Corning Single Mode fiber SMF-28e Optical Fiber 40,000m / 40km

Corning Single Mode fiber SMF-28e Optical Fiber 40,000m / 40km,”This 40km spool of Corning SMF-28e optical fiber delivers excellent optical clarity and minimal signal loss for demanding telecom and research applications. Designed to meet ITU-T G.652.D specifications, this fiber features low attenuation across the entire transmission window, including the water peak region, enabling compatibility with modern WDM systems. Its superior macrobend performance makes it well-suited for tightly packed deployments and advanced network configurations. The 40km span allows users to simulate long-haul fiber paths in a controlled setting, ideal for system development, latency testing, or transmission equipment evaluation. The spool is designed for ease of deployment and secure handling. Bare fiber format allows technicians and engineers to carry out real-time splicing, OTDR testing, or channel monitoring. The spool is widely used in lab test beds, training environments, and manufacturing QA processes where consistency and high fidelity are required. Whether used in metro network emulation or experimental setups, this spool provides dependable, high-performance fiber infrastructure.”
