ST/PC Fiber Connectors: Multimode, Stainless Steel or Ceramic Ferrule
Dust Caps and Strain Relief Boots
ST/PC Connector with
These ST®/PC (Straight Tip/Physical Contact) multimode connectors each have a bayonet-style mount that allows for quick connects and disconnects. Our 10127C connector offers a ceramic ferrule with a Ø127 µm bore, while our 10140G1 connector features a stainless steel ferrule with a Ø144 µm bore. To improve fiber-to-fiber contact, the tips of both ferrules are pre-radiused.
Both connectors are packaged with a connector cap and two strain relief boots: one for Ø900 µm tubing and one for Ø3.0 mm tubing. In addition to the included boots, we offer a boot and crimp sleeve for Ø2 mm tubing (sold below), as well as stainless steel sleeves designed for mating connectors to our stainless steel tubing.
In addition to the standard Ø144 µm bore, the 10140G1 stainless steel ferrule connector can be drilled to accept fiber up to Ø1000 µm. Custom-drilled connectors are available on any stainless steel ferrule; please contact Tech Support for custom requests.
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.
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 ST 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 FC connectors or any Ø2.5 mm ferrule. 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, inspect it before each use, clean it when necessary, and use a fiber connector cap to protect the end face of the connectorized fiber when it is not in use. To aid in inspecting and cleaning connectorized fiber, we offer a selection of inspection tools, as well as fiber optic cleaning products.
