L-com’s line of simplex and duplex APC couplers feature tightly tolerance slots to assure proper orientation of mated APC connectors. In order to achieve low back reflection values some fiber assemblies utilize a connector with an Angled Polish Contact (APC). Our couplers feature a ceramic sleeves to ensure precise alignment and signal integrity.


Brief overview of the Simplex Metal FC APC to FC APC Fiber Optic Coupler from L-com:

  • It is a simplex coupler, which means that it can only be used to connect two fibers.
  • It has FC/APC connectors on both ends. FC connectors are the most common type of fiber optic connector, and APC connectors are a type of connector that helps to reduce back reflection.
  • The coupler is made of metal, which makes it durable and resistant to damage.
  • It has tightly tolerance slots to assure proper orientation of mated APC connectors. This helps to ensure that the connectors are aligned correctly, which minimizes signal loss.
  • The coupler features a ceramic sleeve to ensure precise alignment and signal integrity. The ceramic sleeve helps to protect the fiber optic ferrules and improve the transmission of light.


Here are some of the features and benefits of this coupler in more detail:

  • Low back reflection: APC connectors help to reduce back reflection, which is the light that bounces back off of the connector interface and is not transmitted down the fiber. Back reflection can cause signal loss and noise, so it is important to minimize it in fiber optic applications.
  • Precise alignment: The tightly tolerance slots and ceramic sleeve help to ensure that the connectors are aligned precisely, which minimizes signal loss.
  • Durable and reliable: The metal housing makes the coupler durable and resistant to damage. The ceramic sleeve also helps to protect the fiber optic ferrules from scratches and contamination.


This coupler is a great option for applications where low back reflection and high signal integrity plus precise alignment are important. This component is commonly used in telecommunications, data communications and medical imaging. Contact us today for large project discounts.
