Multimode 50/125 µm, LC-LC, 0.5 m, OM4. Multimode fiber with a fiber diameter of 50/125 µm. Cable length of 7 meters. Optical fiber cable with LC connector. A conventional electrical signal in a copper cable is disrupted by electromagnetic interference. In contrast, fiber optic cables offer better protection against interference and are also more secure against eavesdropping. Additionally, due to the low attenuation of fiber optic cables, long distances can be bridged. The LC connector is a high-performance optical connector for singlemode and multimode applications, characterized by low insertion loss. It is one of the most common types of optical connectors. The design of the LC connector is based on a single-fiber ceramic ferrule with a diameter of 1.25 mm for an optical fiber. Due to its compact design, the LC connector allows for high packing density, making it frequently used in fiber optic switches. The OM classification of an optical fiber defines the quality class of a multimode fiber optic cable. The classification distinguishes four classes (OM1 to OM4). The differentiation is based on the level of optical attenuation and the possible transmission rate and distance. The fiber categories OM3 and OM4 are intended for high-speed applications such as (10/40/100-)Gigabit Ethernet or Fibre Channel at 850 nm. OM4 class multimode fibers have an Effective Modal Bandwidth (EMB) of 4.7 GHz x km.
