Thorlabs' Vytran® Proof Testers apply a set load to a fusion-spliced fiber at a controlled rate in order to test the spliced fiber’s strength. These proof testers feature either a linear proof tester (Item # PTR301) or a rotary proof tester (Item # PTR302). The linear proof tester can perform proof tests with loads up to 20 N (4.5 lbs). The rotary tester can perform proof tests with loads up to 89 N (20 lbs), making it ideal for process qualifications that require very high proof test or tension test levels.

Each PTR301 and PTR302 Proof Tester includes a controller for programming and controling the unit. The user can select parameters such as the load, the rate at which the load is applied, and the hold time.

Proof and Tension Testing
During proof testing, the load is taken up to a predetermined level and released. Proof testing is employed in manufacturing applications to ensure the fiber can support the necessary service load. To ensure the long-term reliability of the spliced fiber, the proof test level should be about three times higher than the intended service load.

When a fiber is tension tested, the load is typically increased to the breaking point of the fiber. Tension testing sacrifies the fiber sample in order to quantitatively assess the mechanical properties of a batch of optical fiber. Because the load required to break a typical optical fiber is high, a rotary proof tester is often used for tension testing. For these reasons, tension testing is best suited for engineering and development applications.

Fiber Block Inserts and Replacement Proof Test Grips
When ordering the PTR301 Linear Proof Tester, it is also necessary to order inserts for its fiber holding blocks. These inserts cover a range of fiber coating diameters from 80 µm to 1000 µm. Custom sizes are also available; please contact Tech Support for more information.

The PTR302 Rotary Proof Tester does not use fiber holding blocks, and thus it is unnecessary to purchase any inserts for its operation. It includes one set of proof test grips; replacement proof test grips are sold separately below in packs of 10.

Handset Controller GUI Interface

The VYT300C handset controller is included with the PTR proof testers. It is also compatible with Vytran large-diameter fiber cleavers as well as Vytran PTR fiber recoaters. One handset controller can be used to configure parameters on multiple fiber processing units in succession. Full instructions for using the handset controller can be found in the manual. The screenshots below highlight key features of the graphical user interface.

The initial screen on VYT300C handset controller gives the option to start the proof test process. Other menus can be accessed by swiping the touchscreen left or right, or by tapping the options at the top of the screen.

Click to Enlarge

During a test sequence, the handset controller monitors the current tension reading, as well as the status of the test.

Click to Enlarge

The suite of tools available through the handset controller includes a proof test history record, which records the target tension and the tension at which a fiber broke.

Click to Enlarge

The tools also allow a copy of the current log file to be saved onto an external memory device.

Click to Enlarge

The Edit menu shows parameters, such as proof test units and level, that can be configured by the user. These parameters are the same as those that can be edited using the tablet controller.

Click to Enlarge

The handset controller can open, save, delete, export, and import files containing parameters for compatible systems. Exporting or importing a file will require a memory device to be connected to the Program Port of the handset controller.

I have one set Vytran PTR-100C. Can it (PG200 Replacement Proof Test Grips for Rotary Proof Testers) used in PTR-100C? If not, please tell me the right Part No. Thanks

Thank you for reaching out to Thorlabs. In this case the design of the proof test grips has not changed since the PTR-100C product line and it is compatible.

Hello, I am a PhD student at the University of Sherbrooke in Quebec. For my PhD thesis related to Silicon Photonics thermomechanical numerical modeling and reliability, I have to do few fibers integrity tests (twist, pull, side pull and cable retention test) according to the Telcordia standard (GR468 and GR326) in order to validate my numerical and reliability models. To realize those experimental tests, I will need a setup that will be able to do the tests. I am writing to know if you are selling any setup that may do the fibers integrity tests. If yes, I wanted to have all the specifications of the setup because I need to do the test on the fibers attached to a package (die and substrate). In order to do so, I need to evaluate the limitation of the dimensions, the loads, the positioning and holding of the package on one side and the 12 fibers (about 125 microns diameter per fiber) cable on the other side. Thank you in advance for taking the time to help me out on this request. Warm regards,

  • Fiber Block Inserts for PTR301 Linear Proof Tester
  • Choose Two Top Inserts and Two Bottom Inserts

When ordering the PTR301 Linear Proof Tester sold directly above, the proper set of inserts needs to be selected. A total of four inserts (two top and two bottom) are required for a fully functioning unit. The inserts are seated in and secured to the fiber holding blocks. They can easily be swapped out for different sizes, allowing our proof testers to adapt quickly should different fiber coating sizes be desired. These inserts are compatible with fiber coatings ranging from Ø80 µm to Ø1000 µm.

Custom sizes are available; please contact Tech Support for additional information.

This handset controller is available as an replacement for the included controller. A single handset controller can be used with multiple systems; after configuring parameters to one fiber processing unit, the controller can be disconnected and then connected to a different unit, of the same or a different type, to configure its parameters.

The handset controller must be connected via the included cable in order to use it. The controller automatically turns on when the connected system is turned on. Upon startup, the handset controller will always read parameters from the connected system; i.e., the parameters that appear on the screen will always be the parameters that have been uploaded to the connected unit. If the parameters read from the unit match the parameters of the most recently opened file on the handset controller, the screen will display the file name.

When used with the proof testers, the controller can edit the level, unit, and time out for the proof tests, as well as the fiber diameter. The main Test screen will show the current tension reading as well as the status of the test, as shown in the screenshot on the right. The suite of tools available through the handset controller includes a proof test history record, which records the target tension and the tension at which a fiber broke. The current log file can also be copied onto an external memory device.

The handset controller can open, save, delete, export, and import files containing parameters for compatible systems. Exporting or importing a file will require a memory device to be connected to the Program Port of the handset controller.

Instructions for using this controller can be found in the manuals for the compatible Vytran systems.
