OS2 and OM1–OM4 indoor fiber optic cables, singlemode and multimode, with LC/LC, LC/SC, LC/ST, SC/SC, SC/ST and ST/ST connectors. Multimode Fiber (MMF) has a core diameter, typically 50–100 micrometers, has ability to transfer multiple modes of light through the fiber core, uses lower-cost electronics (LED, VCSEL) operates at the 850 nm and 1300 nm wavelength and is used for short distance interconnections (up to 550m). In high-speed network infrastructure, choosing the right type of fiber optic cable is essential for performance, cost-efficiency, and long-term scalability. Available fiber types: OM1, OM2, OM3, OM4, OS2 with core sizes 50/125, 62. They share similarities in fiber connectors and application scenarios, which often leads to confusion among users. These fibers are primarily designed for high-speed. In modern enterprise local area networks, campus communication systems, and high-density data center infrastructure, multimode optical fiber acts as the core transmission medium for short-distance high-speed data connectivity. Unlike single-mode fiber designed for long-haul telecom transmission.
