SMA905 connectors, which are most commonly used with multimode fibers, have a stainless steel ferrule design that is ideally suited for large core fibers. Thorlabs stocks a complete selection of SMA905 connector sizes to accommodate our full line of large core fibers, ranging from Ø125 µm to Ø1580 µm. We also offer stainless steel furcation tubing and sleeves that are designed to provide a high degree of fiber protection.
Our standard and hex nut connectors come in a package that includes a fiber connector cap, crimp sleeve, and strain relief boot compatible with Ø3 mm furcation tubing. Both types of connectors have ferrules made out of 303 stainless steel. The hex nut connectors are compatible with any 5/16" wrench and are designed to be used in harsh vibration environments. We recommend tightening the hex nut connector to a torque of approximately 8 in-lbs.
High-temperature connectors manufactured using 304 stainless steel are designed for continuous operation in high-temperature environments up to 250 °C or vacuum down to 10-10 Torr when used with the FTSB1 Stainless Steel Sleeve and 353NDPK Epoxy. These high-temperature connectors are ideal for use with polyimide-coated fiber.
If you need a bore size that is not listed below, please e-mail Tech Support for a quote on connectors with custom-drilled stainless steel ferrules. In addition, we also offer custom patch cables with very rapid turnaround times; please see our Custom Patch Cable Form for more information.
As an alternative to buying and assembling separate optical fiber, connectors, and furcation tubing, Thorlabs also offers pre-built patch cables from stock using the connectors sold on this page. See the table to the right and the Patch Cables tab for a listing of patch cables available that incorporate connectors sold on this page.

(posted 2014-06-16 11:02:08.843) Hello,
Can I order SMA 905 connectors for high power applications? I need air gap SS ferrules for 440-microns diameter fiber. jlow
(posted 2014-07-29 03:52:51.0) Response from Jeremy at Thorlabs: We can offer this for some fiber size. Please contact techsupport@thorlabs.com for a quote. user
(posted 2013-03-21 15:06:36.383) There is the wrong pdf drawing and step file attached, 10230A instead of 11275A. Maybe other data formats are also wrong. tcohen
(posted 2013-03-21 14:59:00.0) Response from Tim at Thorlabs: Thank you for bringing this to our attention! We will correct the mislinked supporting documentation. Please contact us at techsupport@thorlabs.com if you require these files while we are updating the website. Tyler
(posted 2008-08-14 12:22:05.0) A response from Tyler at Thorlabs to aleksey.kharin: Thank you for your excellent suggestion. I am sorry it took so long to get around to making the change. aleksey.kharin
(posted 2008-02-22 09:19:41.0) I think that description to fibers connectors presented onthis page is misleading.
If it is said that this connector is for 600 micron fiber then one will think about fiber of 600 micron core diameter whereas it should be clad diameter.
Sure it can be obveous if one has already some experience with fibers and connectors. Otherwise it is really misleading |

Zoom- Stainless Steel Sleeve for Temperatures up to 250 °C or Vacuum down to 10-10 Torr
The FTSB1 Stainless Steel Sleeve fits fibers with outer diameters up to 720 µm, such as polyimide-coated fiber. It is intended to be used with our high-temperature SMA905 multimode connectors and can withstand environments with temperatures up to 250 °C or vacuum down to 10-10 Torr.
Zoom- CAPM Dust Cap for Ø3.2 mm Ferrules (10 Pack)
- CAPSM Metal Threaded Dust Cap for SMA905 and SMA906 Connectors (4 Pack)
The CAPM Rubber Dust Caps and CAPSM Threaded, Nickel-Plated Brass Caps are both compatible with SMA905 and SMA906 connectors. Additionally, the CAPM Rubber Dust Caps can be used with any Ø3.2 mm fiber connector 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 damage to the connectorized fiber, clean the fiber end face before each use and use a fiber connector cap to protect the end face when it is not in use.
