OM3 and OM4 are laser-optimized, bend-insensitive fibers designed for VCSEL sources, supporting higher data rates and longer distances in modern LANs and data centers. OM5 supports short-wavelength division multiplexing (SWDM), enabling multiple wavelengths over a single fiber for higher aggregate bandwidth, making it ideal for next-generation high-speed networks. Core diameter: OM1 has a larger 62.

5 µm core, while OM2–OM5 have 50 µm cores, allowing more efficient laser transmission. Jacket color helps identify fiber type in installations: orange for OM1/OM2, aqua for OM3/OM4, and lime green for OM5. Bandwidth is measured as Effective Modal Bandwidth (EMB) at 850 nm, with OM4 and OM5 providing higher EMB for longer distances and higher-speed applications.

This table provides a quick reference for selecting the appropriate multimode fiber type based on network speed, distance, and optical source requirements, ensuring compatibility with enterprise and data center standards.
