What is multimode fiber ? How to choose the right one ?
Multimode fiber is an optical fiber designed to carry multiple light rays (modes) simultaneously through a relatively large core . Think of it as a wide hallway where many people can walk side-by-side, but they take slightly different paths and arrive at slightly different times. Multimode fiber is the "workhorse" of short-distance, high-bandwidth optical communication. It offers the perfect balance of performance and cost for applications where signals need to travel fast, but not far. The OM1→OM5 evolution shows how innovation continues to extend multimode's capabilities, ensuring its place in modern networks despite the rise of single-mode solutions. Transmission Windows Multimode primarily operates at: 850nm (main window for high-speed) 1300nm (secondary window, less common today) OM5 Innovation: Supports 850-953nm range for wavelength division multiplexing (SWDM) over multimode.
