Comparison of Multimode Fibers

Fiber optic patch cord knowledge brief Published 13 Jul 2024

Prepared for preliminary research by the JEWELBLU OPTICAL knowledge desk. Confirm connector types, fiber grades, polish, loss budgets and installation requirements against current standards and product documentation.

Multimode fibers differ in core size, bandwidth, supported data rates, maximum distances, optical sources, and applications, with OM1/OM2 suited for legacy networks and OM3/OM4/OM5 optimized for high-speed data centers.

Overview of Multimode Fiber

Multimode fiber (MMF) has a larger core diameter (50–62.5 µm) than single-mode fiber, allowing multiple light modes to propagate simultaneously. This enables short-range, high-bandwidth communication using lower-cost optical sources like LEDs or VCSELs, making MMF ideal for data centers, enterprise LANs, and campus networks . ISO/IEC 11801 defines five main types: OM1, OM2, OM3, OM4, and OM5.

  • OM1 and OM2: Early-generation fibers with LED sources, suitable for short distances and lower-speed networks. OM1 has a larger 62.5 µm core, while OM2 uses 50 µm. Both are largely obsolete for modern 10G+ applications .
  • OM3 and OM4: Laser-optimized 50 µm fibers designed for VCSEL-based transceivers, supporting higher bandwidth and longer distances. OM4 improves on OM3 with enhanced modal bandwidth, making it the mainstream choice for new data center deployments .
  • OM5: Introduced in 2016 as Wideband Multimode Fiber (WB-MMF), OM5 supports Short Wavelength Division Multiplexing (SWDM), allowing multiple wavelengths (850–940 nm) on a single fiber. This reduces fiber count for high-speed 40G/100G/400G applications, though adoption is limited due to higher cost and SWDM module availability .
Practical Considerations
  • Distance vs. Data Rate: Higher-speed links (40G/100G) require OM3/OM4/OM5 for distances beyond 100 m. For most enterprise links under 100 m, OM3 performs similarly to OM4, making OM4 sometimes costlier without added benefit .
  • Optical Source Compatibility: OM1/OM2 use LEDs, while OM3/OM4/OM5 are optimized for VCSEL lasers, which are more efficient and cost-effective for high-speed applications .
  • Color Coding: OM1/OM2 are orange, OM3/OM4 aqua, and OM5 uses aqua or Erin violet for easy identification .
  • Deployment: OM1/OM2 are mostly found in legacy buildings, while OM3/OM4/OM5 are standard in modern data centers and enterprise networks .
Conclusion

Choosing the right multimode fiber depends on network speed, distance, optical source, and budget. For legacy or low-speed networks, OM1 or OM2 may suffice. For modern high-speed data centers, OM3 or OM4 is cost-effective, while OM5 is ideal for future-proofing with SWDM and ultra-high-speed applications. Understanding these differences ensures reliable, scalable, and cost-efficient network design .
