MM SC Connectors, Ceramic or LCP Ferrule


SC Fiber Connectors: Multimode

  • Pre-Radiused Cermaic Ferrule Version Minimizes Back Reflections
  • SC Glue-On Connector with LCP Ferrule Compatible with Graded-Index Plastic Optical Fibers


  • SC Style Connector
  • Choice of Ceramic or LCP Ferrule
  • Comes with Dust Cap and Strain Relief Boot for Ø3 mm Tubing
  • Ceramic Ferrule Version Includes an Additional Strain Relief Boot for Ø900 µm Tubing

Thorlabs offers two types of SC style connectors. The 30126H1 SC Style Connector features a pre-radiused (R = 20 mm) ceramic ferrule that minimizes back reflections. The connector has a bore size of Ø125 µm.

The SC 30500A1 SC Style Glue-On Connector is compatible with graded-index plastic optical fibers (GIPOF). The standard SC form factor has an LCP (grey plastic) ferrule that allows for direct connection with no buffer removal. Thorlabs recommends the use of F120 fast room temperature cure epoxy to secure the terminated fiber. The connector has a bore size of Ø494 µm.

Additionally, we offer stainless steel sleeves designed for mating connectors to our stainless steel tubing.

Strain Relief Boots and Dust Caps

* Strain Relief Boots and Crimp Sleeves for Ø2 mm Tubing (25 Pack)
* CAPF Dust Cap for Ø2.5 mm Ferrules (25 Pack)

Thorlabs offers strain relief boots and dust caps that can be purchased separately from our fiber connectors. The black strain relief boots sold here are compatible with SC connectors and Ø2 mm furcation tubing (our stock connectors do not include a boot compatible with Ø2 mm tubing).

The CAPF Dust Cap is for use with Ø2.5 mm fiber connector ferrules. Dirt on the fiber tip can result in permanent damage to the fiber connector, which can increase coupling losses or create undesirable mode structures in the output light. To prevent damaging the connectorized fiber, clean it before each use and use a fiber connector cap to protect the end face of the connectorized fiber when it is not in use.


Our Mission is to accelerate the advancement of optical technology for precision measurements and their applications from the table tops of research laboratories to standard use in communication and high technology industries. Our aim is to serve our customers. Our hope is to create a place for highly skilled people in an open environment
