Data Center Cabling

OM4 and OM5 fiber cables power modern data centers, campus backbones, and SWDM-ready networks. See where each multimode fiber fits — and when OM5 is worth the premium.

OM4 multimode fiber reaches 550 m at 10G, 150 m at 40G, and 100 m at 100G. See how it compares to OM1/OM2/OM3 and which factors limit its real-world distance.

Is OM2 obsolete? Not quite — OM2 still fits 1 Gbps and short-reach 10 Gbps links, but OM3/OM4 now dominate new builds. Here's when OM2 still makes sense.

OM1 is cost-effective for older or small-scale networks, while OM2 delivers higher bandwidth and longer reach for medium-range, modern infrastructure. Here's how to choose.

OM1, OM2, OM3, and OM4 multimode fibers differ in core diameter, modal bandwidth, reach, color code, and cost. Compare all four at a glance.
