PATCHBOX 365 Fiber Optic Cassette. Retractable patch cables for perfect patching. Replaceable modular cassette system. Cable length: 0.8 m. Fiber quality: OM4. Retractable patch cables for the perfect length. Connectors: LC - SC. Replaceable modular cassette system with integrated cassette labeling. Cable stopper for precise cable length adjustment. SC connectors. SC connectors are standard connectors for fiber optic cabling. They feature automatic locking and twist protection. Their use is recommended for new installations of computer networks with fiber optic technology. The connector is suitable for single-mode and multi-mode fibers. It can be used for simplex, duplex, and multi-connection setups. LC connectors. The LC connector is a high-performance fiber optic connector for single-mode and multi-mode 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. OM4 classification. The OM designation for a fiber optic cable defines the quality class of a multi-mode 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 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 multi-mode fibers have an Effective Modal Bandwidth (EMB) of 4.7 GHz x km.
