In fiber optic systems for data centers, LC, SC and MPO optical fiber connectors are often used.

  • SC (square connector) connectors have a push-pull coupling end face with a spring-loaded ceramic ferrule, and is ideal in data center applications.
  • LC (Lucent connector) connectors – also push-pull connectors – came along after SC connectors, and feature a smaller ferrule (for this reason, it’s known as a “small form-factor connector”). Its smaller size makes it ideal for dense data center racks and panels.
  • MPO connectors are used for mmulti-cables with anywhere from eight to 24 fibers.
