SMA905 Connector with Ø128 µm Bore
High-Temperature, Vacuum-Compatible SMA905 Connector with Ø245 µm Bore
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 connectors come in a package that 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 connector caps can also be purchased separately below.
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.
Stock Patch Cables Available with These Connectors
As an alternative to buying and assembling separate optical fiber, connectors, and furcation tubing, Thorlabs offers pre-built patch cables from stock using the connectors sold on this page. Stocked patch cables are available with multimode or single mode optical fiber, as indicated by the table to the right. Additionally, Thorlabs offers Custom Patch Cables with same-day shipping, which can be constructed using the connectors sold on this page.
The black strain relief boots sold here are compatible with SMA connectors and Ø2 mm furcation tubing (our stock connectors do not include a boot compatible with Ø2 mm tubing). 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.
The CAPM Rubber Dust Caps and CAPMM 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.
