Multimode LC-ST OM3 1 m. Cable length: 1 m. Fiber quality: OM3. Connectors: LC - ST. Multimode fiber with a fiber diameter of 50/125 µm. A conventional electrical signal in a copper cable is disturbed 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 covered. ST connector. ST "stick and twist" connectors feature a bayonet lock for fiber optic cables. They are suitable for both single-mode and multimode fibers. LC connector. The LC connector is a high-performance fiber optic connector for single-mode and multimode applications, characterized by low insertion loss. It is one of the most common types of fiber optic connectors. The design of the LC connector is based on a single-fiber ceramic ferrule with a diameter of 1.25 mm for a fiber optic cable. Due to its compact design, the LC connector allows for high packing density, making it frequently used for fiber optic switches. OM3 classification. The OM designation for a fiber optic cable defines the quality class of a multimode fiber optic cable. The classification distinguishes four classes (OM1 to OM4). The distinction is made based on the level of optical attenuation and the possible transmission rate and distance. The OM3 and OM4 fiber categories are intended for high-speed applications such as (10/40/100-)Gigabit Ethernet or Fibre Channel at 850 nm. OM3 multimode fibers have an Effective Modal Bandwidth (EMB) of 2 GHz x km.
