    MU Connectors

    The MU Fiber Optic Connector, or Miniature Unit Connector, is used for compact multiple optical connectors and a self-retentive mechanism for backplane applications. Featuring a simple push-pull design and compact miniature body, the MU has a 1.25mm ferrule diameter like the LC Connector, similar in size and design to the SC Connector but with a smaller footprint allowing for more connectors to be installed in a given space. Developed as a small form factor connector for telecommunications and data communication systems, the MU Connector is unique for its ability to fit two channels in the same footprint as one SC Connector.
