Singlemode LC-LC Duplex OS2 0.25 m. Cable length: 0.25 m. Fiber quality: OS2. Duplex. Connectors: LC - LC. Serial number on each cable. The LC connector is a high-performance fiber optic connector suitable for both singlemode and multimode applications, featuring low insertion loss. It is one of the most commonly used fiber optic connector types. 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. General information about fiber optic cables: Equivalent terms for fiber optic patch cables can include patch cords, adapter cables, connection cables, or jumpers. While a conventional signal in a copper cable can be subject to electrical interference, fiber optic cables operate using light. Therefore, they cannot be affected by external electromagnetic interference, nor do they interfere with other lines or signals, as they do not emit any radiation. Additionally, due to the low attenuation of optical cables, distances of well over 100 km can be covered without optical amplification.
