Longest effective distance for fiber optic patch cords
OM4 is common for distances up to 150 meters in 100G SR4 applications, while OM5 (Wideband Multimode Fiber) is optimized for short-wave division multiplexing (SWDM). These fibers are designed to carry large amounts of data over long distances with minimal signal loss. These rating positions are standard for the industry, because they are adopted as ISO/IEC 11801 and IEC 61300-3-35, following which patch cords should not be less than 2 m but not more than 10 m in office environments. Multimode Fiber (MMF): suitable for short-distance transmission, common specifications for OM1, OM2, OM3, OM4, OM5, of which OM3/OM4/OM5 support higher. Since there can be issues with even shorter fiber cables we recommend only using fibers with that minimum length. If you need a smaller cable length please contact us and we can discuss the issue. Executive Summary: With data center traffic doubling every three years and enterprise networks pushing toward 400G and 800G speeds, choosing the wrong fiber optic patch cable does more than create a bad connection—it creates a cascading performance bottleneck that haunts your operations team for.
