    • Advantages:
      • Much further distances (e.g., OS2 up to 10 kilometers for 10G).
      • Good for WAN network “applications”.
    • Disadvantages:
      • Higher cost (depending on where you buy, up to 6-times more expensive).
  • Multimode have shorter reach though are because of their price better suited, for, e.g., in datacenter usage.
    • Wikipedia
    • Advantages:
      • Lower cost (in comparison with Singlemode).
      • Compatible with many different data protocols, e.g., ethernet.
    • Disadvantages:
      • Nowhere near the distance of Singlemode (e.g., OM4 10G distance is “only” up to 550 meters).
