Thorlabs' FiberBench Polarization Controller Kit allows you to transform an arbitrary input polarization state into an arbitrary output polarization state. The controller uses two FiberPorts mounted on either side of a Single-Axis FiberBench with HCA3 Wall Plates. Any input polarization state can be deterministically rotated into a known output polarization state using a quarter-wave, half-wave, and another quarter-wave plate mounted (in this order) between the two FiberPorts. Each plate can be precisely and continuously rotated through 360°.

Advantages over Traditional Fiber Paddle Controllers

The FiberBench polarization controller has the same function as a paddle controller, while offering a more deterministic and stable polarization manipulation. Without a polarimeter, the SOP from the paddle controller cannot be determined directly. Since it does not have any hysteresis, it is possible to predict the controller's output State of Polarization (SOP) at any instant in time given only its input SOP. Unlike the conventional fiber paddle controllers, the FiberBench polarization controller can be used with PM or SM fiber without the need for splicing. Additionally, it benefits from the advanced design of the FiberBench series and has high thermal and mechanical stability. The continuous, 360° rotation and precise control offered by the wave plates allow the user more control and a more stable platform than is possible with the paddle controllers.

Smart Pack

  • Reduce Weight of Packaging Materials
  • Increase Usage of Recyclable Packing Materials
  • Improve Packing Integrity
  • Decrease Shipping Costs

Thorlabs' Smart Pack Initiative is aimed at waste minimization while still maintaining adequate protection for our products. By eliminating any unnecessary packaging, implementing packaging design changes, and utilizing eco-friendly packaging materials for our customers when possible, this initiative seeks to improve the environmental impact of our product packaging. Products listed above are now shipped in re-engineered packaging that minimizes the weight and the use of non-recyclable materials.b As we move through our product line, we will indicate re-engineered packages with our Smart Pack logo.

  • Travel-based emissions reduction calculations are estimated based on the total weight reduction of packaging materials used for all of 2013’s product sales, traveling 1,000 miles on an airplane, to provide general understanding of the impact of packaging material reduction. Calculations were made using the EPA’s shipping emissions values for different modes of transport.
  • Some Smart Pack products may show a negative weight reduction percentage as the substitution of greener packaging materials, such as the Greenwrap, at times slightly increases the weight of the product packaging.

Hello: I am interested in your "FiberBench Polarization Controller Kit" products(PC-FFB-1550). Could you please give us the product's spec. (We want to know the PER of this element). Thank you~ Hua-Kung Chiu

Hello, thank you for contacting Thorlabs. The waveplates will change the polarization state, but not the degree of polarization. I will reach out to you directly to discuss how you might define PER for a system like this, but the degree of polarization should be very similar on the input and output.

Dear Concern person, Could you explain more detail about "FiberBench Polarization Controller Kit". I can use it for connector PR measurement ,Right? Do you have another connector adapter for change? (LC , SC , MU etc...) Best regards, Pinyo Somean

Response from Javier at Thorlabs to ygyang2004: Thank you very much for contacting us. The components in the PC-FFB-1550 polarization controller can certainly be disassembled. Also, we can offer a version with different components as required in your application (we actually use the PAF-X-2-C in this controller). Keep in mind that at different wavelengths the resulting insertion loss will most likely be different. I will contact you directly for further support.

Hello. Im Yoon seok Yang in ajou university master course. I wonder that PC-FFB-1550, fiber bench model can be separated. And I wonder that PC-FFB-1550 model can be assemble with another component(for example PAF-X-2-C-Fiberport, PCB-2.5-VIS etc..). Customer Email:
