CA2812 Standard SMA-to-BNC Adapter Cable CA2912 Standard SMA-to-SMA Cable SMM12 Premium SMA-to-SMA Microwave Cable SMGF3 Premium SMA-to-SMP Microwave Adapter Cable ![]() Please Wait All the cables sold by Thorlabs that have an SMA connector on at least one end are displayed on this page. The selection of cables below includes both standard cables and Thorlabs' Premium Microwave Cables. The following links will take you to web pages that contain cables with BNC, SMC, USB, and Banana connectors. A preset torque wrench is available below to ensure that the proper mating torque is supplied when connecting two SMA connectors.

Thorlabs’ SMA-to-SMA Microwave Cables support frequencies from DC up to 26 GHz. Each flexible cable is terminated with an SMA male connector on either end (see the image to the right). They are available in lengths ranging from 3" to 120". Each cable has a low VSWR from DC to 26 GHz as well as a low insertion loss. In general, we recommend using the shortest cable that is suitable for your application. The SMA connector can mate directly to a 2.92 mm, 3.5 mm, or K connector. As a result, these cables are compatible with many of Thorlabs’ High-Speed Detectors or Fiber-Coupled EO Modulators that use SMA connectors. For more information on Thorlabs’ full selection of Premium Microwave Cables for high-frequency applications, see the full web presentation. A preset torque wrench is available below to ensure that the proper mating torque is supplied when connecting these cables. A torque wrench with a preset torque value should always be used to mate these coaxial connectors. Not doing so can damage the cable or reduce its overall performance. ![]() ![]() Click for Details Boot Style May Vary

Thorlabs’ Premium Microwave Adapter Cables have an SMP female connector on one end and either a male or female SMA connector on the other. Each style of adapter cable is available in 3" or 6" lengths. Each cable has a low VSWR of ≤1.4 from DC to 18 GHz, as well as a low insertion loss (see the table below). In general, we recommend using the shortest cable that is suitable for your application. The SMP connector can mate directly to a GPO® connector, while the SMA connector can mate directly to a 2.92 mm, 3.5 mm, or K™ connector. The GPO connector compatibility makes these cables suitable for use with Thorlabs’ Fiber-Coupled EO Modulators. For more information on Thorlabs’ full selection of Premium Microwave Cables for high-frequency applications, see the full web presentation. A preset torque wrench is available below to ensure that the proper mating torque is supplied when connecting these cables. A torque wrench with a preset torque value should always be used to mate these coaxial connectors. Not doing so can damage the cable or reduce its overall performance.
![]() ![]() Click to Enlarge The Wrench is Engraved for Easy Identification in the Field
These 5/16” Torque Wrenches have a preset torque value of 5 in-lbs to prevent over-tightening most SMA connectors. When the preset torque value has been achieved, the break-over design will cause the pivoting joint to bend. This will prevent further force from being applied to the connector. The wrench's hex head will move back into place once the force is removed. Each wrench is engraved with its preset torque value, torque direction, wrench size, and item # for easy identification in the field. The preset torque value for each wrench is guaranteed for one year from the date of purchase. If necessary, the wrench may be returned to Thorlabs for recalibration, please contact Tech Support for details. ![]()
The T1508 is a test lead holder for wires up to 0.210" (5.33 mm) in diameter and has 14 slots for cables. It is ideal for holding fiber optic patch cables. The T2708 is a test lead holder for wires up to 0.450" (11.43 mm) in diameter and has 9 slots for cables. The cable racks are made from cold rolled steel with a baked enamel finish. The wall mounting holes are separated by 3" (76.2 mm). Both racks are 11" (279 mm) long and extend outward from the wall by 3.5" (88.9 mm). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
