  • What is the main difference between single-mode and multimode couplers?
    Single-mode couplers are designed for long-distance transmission with a smaller core size, while multimode couplers are used for shorter distances and higher core sizes.
  • Can this coupler be used with LC connectors?
    No, this model is specifically designed for SC interface connections. LC requires a different keystone coupler type.
  • What is the benefit of a keystone design?
    It allows fiber connections to be neatly integrated into wall plates or patch panels for structured and modular cabling systems.
  • Is this suitable for FTTH applications?
    Yes, SC single-mode couplers are widely used in FTTH networks and broadband access systems.
  • Is installation tool-free?
    Yes, the keystone snap-in design allows quick and easy installation without special tools.
