This is a multimode fiber jumper used for connecting high-performance network devices with different interface types. It features a high-density LC connector on one end and a structurally stable SC connector on the other, perfectly solving the issue of physical interface mismatch between devices. Its core value lies in the ability to directly connect devices with LC and SC ports without the need for an adapter, while also providing high-performance transmission support for 40G and 100G applications at OM4 level.
