L-com's simplex metal FC couplers are designed for mounting in D shaped holes used for simplex ST couplers. This series features either bronze or ceramic alignment sleeves to meet your specific design requirements. Additionally, these adapters can be used with PC or UPC style fiber connectors.


Here are some additional details about the features of L-com's simplex metal FC fiber optic couplers with D-hole mounting:

  • The alignment sleeves are available in two materials: bronze and ceramic. Bronze sleeves are less expensive, but ceramic sleeves offer better performance and durability.
  • The couplers can be used with PC or UPC style fiber connectors. PC connectors have a polished end face, while UPC connectors have a non-polished end face.
  • The metal housing of the couplers provides durability and protection from the environment.
  • The couplers have low insertion loss and high return loss, which ensures that the optical signal is not degraded when it passes through the coupler.
  • The couplers meet or exceed Telcordia GR-1430-CORE specifications, which are the industry standard for fiber optic components.


These components are optimal for use in a variety of fiber optic applications, including telecommunications, networking, medical imaging, industrial automation and military and aerospace. If you are looking for a reliable and durable fiber optic coupler for your application, then L-com's simplex metal FC couplers with D-hole mounting are a great option.
