The LC and FC connectors are designed with threaded bodies for high-vibration environments, commonly used with single-mode and polarization-maintaining optical fibers. A popular configuration is the LC/UPC to FC/UPC patch cord, featuring LC/UPC termination on one side and FC/UPC on the other.
Termination options include Single mode UPC, APC, or Multimode PC. Standard cables typically use single mode G652D, with alternatives like G657A1, G657A2, G657B3, or Multimode OM1 through OM5.
