All Lightwin fiber optic patch cables are processed with special ferrules and manufacturing methods to create a high-quality product. These cables are suitable for all fiber optic applications in various areas of telecommunications. Typical applications include patching in data centers, server or network cabinets, as well as in FTTH (Fiber to the Home). By using single-mode ferrules for the Lightwin multimode patch cables and specially selected ferrules with minimal tolerances for the Lightwin single-mode patch cables, attenuation values are achieved that far exceed the required standards according to ISO/IEC.
