Multimode optical fiber supports distances ranging from 33 meters to 550 meters depending on fiber type and data rate.

Distance by Fiber Type and Data Rate

  • OM1 (62.5 µm core): Supports up to 275 meters at 1 Gbps and 33 meters at 10 Gbps. It is typically used for low-speed applications like 100 Mbps Ethernet and uses LED light sources .
  • OM2 (50 µm core): Can transmit up to 550 meters at 1 Gbps and 82 meters at 10 Gbps. It is suitable for medium-speed applications and also uses LED sources .
  • OM3 (50 µm laser-optimized): Designed for high-speed Ethernet, supporting 300 meters at 10 Gbps, 100 meters at 40 Gbps, and up to 100 meters at 100 Gbps. It uses VCSEL lasers for improved performance .
  • OM4 (50 µm laser-optimized): Enhanced for higher bandwidth, supporting 550 meters at 10 Gbps, 150 meters at 40 Gbps, and 150 meters at 100 Gbps. It is backward compatible with OM3 .
  • OM5 (50 µm wideband multimode): Supports Short-Wavelength Division Multiplexing (SWDM) and can transmit 150 meters at 40 Gbps and 100 meters at 100 Gbps, offering higher bandwidth for modern data centers .

Factors Affecting Maximum Distance

  1. Data Rate: Higher speeds reduce the maximum distance due to modal dispersion and signal attenuation.
  2. Light Source: LEDs have lower modulation rates, limiting distance, while VCSEL lasers allow longer reach at high speeds .
  3. Fiber Quality: Laser-optimized fibers (OM3/OM4/OM5) reduce modal dispersion and support longer distances.
  4. Network Design: Connectors, transceivers, and environmental factors like bends or splices can affect effective transmission distance .

Summary

For short-range, cost-effective connections within buildings or data centers, multimode fiber is ideal. OM1 and OM2 are suitable for lower-speed, shorter distances, while OM3, OM4, and OM5 are optimized for high-speed Ethernet and modern data center applications, supporting distances up to 550 meters at 10 Gbps. Choosing the appropriate fiber type depends on the required data rate, distance, and future scalability.
