OM3 or OM4 — How to Choose
Both cables deliver excellent performance. Use these factors to determine which fiber type best fits your network requirements.
Consider Transmission Distance
Choose OM4 if your runs exceed 100m at 40/100G or 300m at 10G — otherwise OM3 covers most standard deployments.
Plan for Future Growth
OM4 offers extended reach and higher bandwidth headroom, making it the better choice for networks expected to scale.
Evaluate Network Density
Both use LC connectors — ideal for high-density panels and closets where space efficiency is a priority.
Account for Environment
For outdoor or harsh conditions, ruggedized jacket options are available for both OM3 and OM4 variants.
