3SAE Linear Tensile Tester

The 3SAE Linear Tensile Tester is an automated tension tester for optical fibers with cladding diameters ranging from 80-400 μm in diameter. The fiber clamps accommodate coatings up to 1000 μm in diameter.


The 3SAE Linear Tensile Tester incorporates easy, single button fiber loading and an automated tension test process. The built in LCD reports an acceptable “pass” result and maximum tension, in Newtons (N) or Kpsi, applied to the optical fiber during the proof test. The 3SAE Linear Tensile Tester also supports destructive testing of optical fiber by pulling and displaying the maximum achieved tension.


The built in LCD and keypad ensures stand-alone operation and provides the operator easy access to software adjustable clamp pressure, maximum tension, tension rate and proof test hold times in 10 user selectable and customizable tension programs. These features, in combination with the compact design allows for extreme portability and flexibility for use with optical fiber in laboratory or production environments.


The 3SAE Linear Tensile Tester includes a universal AC-12V DC power supply and requires no additional external connections, such as air, for operation or PC for configuration. An available RS-232 port provides the ability to update the firmware and supports data collection from any appropriately configured computer.
