  • What is the purpose of a loopback cable
    A loopback cable is used to test optical ports by returning the transmitted signal back to the source for verification.
  • What does OM1 62.5/125 mean
    OM1 refers to multimode fiber with a 62.5μm core and 125μm cladding, typically used in legacy short-distance networks.
  • Can this be used in high-speed 100G systems
    OM1 is generally not recommended for high-speed 40G/100G applications; OM3 or OM4 is preferred for modern high-speed networks.
  • Is it compatible with MPO/MTP ports
    Yes, it is fully compatible with standard MPO/MTP interfaces when fiber count and polarity match.
  • Can fiber type be customized
    Yes, we support customization for different multimode and single-mode fiber types depending on application needs.
