Large corporations utilize multimode fiber to link different departments within a campus. Multimode fiber is a type of optical fiber primarily used for data transmission over short to medium distances. It features a core that is larger in diameter compared to single-mode fibers, typically around 50 to 62. This characteristic enables them to transmit data at high speeds over relatively short distances, making them an essential component in various optical and photonic. Use this multimode fibers buying guide to compare major types, define selection criteria, and find suppliers: Professional purchasing of high-value photonics products is a substantial responsibility, where a structured decision-making process is essential.
