The Hybrid Adapter is used to connect single-mode or multi-mode fibers with SC/UPC – FC/UPC connectors, which are the most common in distribution panels. It connects cables with pigtails that have been spliced to the optical cable. Single-mode adapters feature a ceramic central element and are manufactured with higher precision than multi-mode adapters. The device can be used in high-speed data transfer applications. The signal in single-mode fibers does not disperse, and data flows parallel to the axis, reaching the end of the fiber in a single mode without reflections. Single-mode fibers are an ideal solution for long-distance optical fiber communication, as the signal can be transmitted without amplification over distances of up to 100 km.
