Multimode Fiber Optic Cable Types: OM1 vs OM2 vs
These multimode fiber types vary based on core diameter, bandwidth, maximum distance and application suitability. This article dives into this

This fiber is a bend-insensitive, graded-index multimode fiber designed for transmission speeds of 1 Gbps but also appropriate for transmission speeds of up to 10 Gb/s. " A key feature of multimode fiber is that it has a larger core (the glass part in the middle) than other types. To recap Optical Fiber can be divided into Multimode Fiber (MMF) and Single-Mode optical fiber (SMF). 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. Its ability to guide light through a predominantly air‑filled core rather than solid glass enables tangible performance gains, most notably lower attenuation, reduced latency, and. This guide explains the five generations of multimode fiber - OM1, OM2, OM3, OM4, and OM5 - covering their physical characteristics, color coding, bandwidth, maximum distances at different data rates, optical sources (LED, VCSEL, SWDM), and real-world applications in enterprise networks and data.
