CORNING SMF-28e+ SINGLE MODE FIBER 20,000m / 20km Spool

CORNING SMF-28e+ SINGLE MODE FIBER 20,000m / 20km Spool,”This 20km spool of Corning SMF-28e+ single-mode fiber provides exceptional optical performance over long distances, making it ideal for simulation of real-world telecom networks in lab or training environments. The SMF-28e+ fiber type features low attenuation and tight geometrical tolerances, enabling seamless integration with high-speed systems including 10G, 40G, and 100G networks. With compliance to G.652.D standards, it offers reduced water peak loss and superior bend performance, particularly important in dense installations. The bare fiber format on a spool allows easy access for fusion splicing, OTDR testing, and connectorization. This makes it ideal for calibration tasks, equipment validation, and temporary network setups. With its consistent dispersion and low PMD, this fiber supports DWDM/CWDM transmission and ensures minimal signal degradation across all wavelengths. The 20km length provides enough span for latency simulation or for constructing passive long-loop testbeds. The spool itself is durable, designed to support smooth unwinding and secure storage. It’s widely used in telecom engineering, product development, training institutes, and fiber optic equipment manufacturing.”
