Thorlabs offers FC/PC connectors with 2.0 mm narrow keys and drilled stainless steel ferrules. These connectors come with bore sizes ranging from Ø125 µm to Ø1580 µm, providing compatibility with various multimode fibers. Each connector package includes a fiber connector cap, crimp sleeve, and strain relief boot compatible with Ø3 mm furcation tubing. Strain relief boots for Ø2 mm furcation tubing and additional connector caps can be purchased separately below. We also offer stainless steel sleeves designed for mating connectors to our stainless steel tubing. Please refer to stainless steel tubing and sleeves for more information.
If you need a bore size that is not listed below, please e-mail Tech Support for a quote on custom-drilled connectors.
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.

What is the recommended crimp die size for the 2mm crimp sleeves to 2mm tubing?

Thank you for reaching out to us with this inquiry Chad. Unfortunately we do not have a singular product to recommend for this particular application. Rather, the solution involves our crimp tool (CT042) in addition to some epoxy. We have a note on the page above stating as much: Please note that, due to the small size of this tubing, epoxy must be used after crimping a sleeve from the 190066CP or 190088CP packs to the tubing to ensure that it is properly secured to the tubing. Additionally I have reached out to you to discuss this.

Hello, Can you recommend a connector for connecting dissimilar fibres, e.g. glass to pof and glass to gi-pof. Thanks, Dave.

Response from Phong at Thorlabs: If you are looking to mate two fiber patch cables together, I would recommend using a mating sleeve that accepts your patch cables' connector type. http://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=314 We will contact you directly to discuss your specific requirements.

- Strain Relief Boots and Crimp Sleeves for Ø2 mm Tubing (25 Pack)
- CAPF Dust Cap for Ø2.5 mm Ferrules (25 Pack)
- CAPFM Threaded Metal Dust Cap for FC Connectors (4 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 include a crimp sleeve and are compatible with FC/PC and FC/APC connectors and Ø2 mm furcation tubing (our stock connectors do not include a boot compatible with Ø2 mm tubing).
The CAPF Clear Plastic Dust Caps are for use with all Ø2.5 mm fiber connector ferrules and FC connectors, and the CAPFM Threaded Nickel-Plated Brass Dust Caps are for use with narrow-key FC connectors. 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 before each use with an appropriate fiber and connector cleaning product and use a fiber connector cap to protect the end face of the connectorized fiber when it is not in use.
