This SC/PC (Subscriber Connector / Physical Contact) single mode connector allows for quick and easy assembly of the inner frame into the outer housing via a snap-in mechanism and features a pre-radiused ceramic ferrule that minimizes back reflections. The connector comes complete with a strain relief boot for both Ø3 mm and Ø900 µm tubing and a fiber connector cap. It also features a hole size tolerance of +1 µm / -0 µm and a maximum concentricity of 1 µm.

For information about polishing and terminating fibers, please see our FN96A Connectorization Guide.

As an alternative to buying and assembling separate optical fiber, connectors, and furcation tubing, Thorlabs also offers custom pre-built patch cables using the connectors sold on this page. See our Custom Fiber Patch Cable Configurator to place an order.

Please add the width of the key used on all the FC connectors, you have this data on the FC to FC bulkheads and it would be good to be able to match up the data.

Dust Caps

Our CAPF Clear Plastic Dust Caps are for use with all Ø2.5 mm fiber connector ferrules and FC connectors, while our CAPFM Threaded Nickel-Plated Brass Dust Caps work with any narrow-key FC connector. Dirt on the fiber tip can cause permanent damage to the fiber connector, which can result in increased coupling losses or undesirable mode structure 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.
