Common Types of Multimode Fiber

The types of multimode fiber classified by the ISO 11801 standard include:

  • OM1: 62.5 µm core size, suitable for short distances.
  • OM2: 50 µm core size, supports higher bandwidth than OM1.
  • OM3: 50 µm core size, optimized for 10 Gb/s Ethernet over distances up to 300 meters.
  • OM4: 50 µm core size, supports 100 Gb/s Ethernet over distances up to 150 meters.
  • OM5: 50 µm core size, designed for wideband multimode applications, supporting multiple wavelengths .

These multimode fibers are commonly used in various networking applications, with OM3, OM4, and OM5 being the most prevalent in modern installations .
