The 3SAE Linear Tensile Tester LD (LTT-LD) is an automated tension tester for large diameter optical fibers with cladding diameters ranging from 125-1000 μm in diameter.  The fiber clamps accommodate coatings up to 1000 μm in diameter.

The LTT-LD incorporates large bend radius mandrels to accommodate large diameter fiber 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 – Large Diameter 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 parameters such as maximum tension, tension rate and proof test hold times in 10 user selectable and customizable tension programs. These features allow for extreme flexibility for use in laboratory or production environments.

The LTT-LD includes a universal AC-12 VDC 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.
