2-Paddle Manual Polarization Controllers-Ø18 mm Loop

General Features

2 Paddles Provide 2 Independently Rotatable Wave Plates
18 mm (Ø0.71″) Fiber Loops
Each Paddle Provides ±143° of Rotation
Available Empty or Preloaded With FC/APC-Terminated Fiber
Replacement Ø900 µm Jacketed FC/PC or FC/APC Patch Cables Available

DKP Miniature 2-Paddle Fiber Polarization Controllers use stress-induced birefringence to create two independent wave plates to alter the polarization of the transmitted light in single mode fiber. The two fractional wave plates are created by looping the fiber around two independent spools. For the polarization controllers preloaded with fiber, the paddles are configured to approximate a quarter-wave plate and a half-wave plate when used at the design wavelength.

The 2FPC0180 polarization controller is empty, allowing customers to insert a single mode fiber with a Ø900 µm jacket. Additionally, we have Ø900 µm jacketed FC/PC and FC/APC patch cables available from stock that are suitable for use with these controllers. The other four controllers come preloaded with fiber. The fibers in the preloaded controllers can also be removed and replaced by the user if the controllers are needed for a new application in the future. To ensure proper usage of the controllers, fiber cables must be long enough to achieve the recommended number of loops. To ensure proper usage of the controllers, fiber cables must be long enough to achieve the recommended number of loops.

The fiber is secured around two removable spools with a lip and two clamps at the ends of the controller. The spool covers have knobs for easy loading and unloading and the clamps are held in place by screws. If needed, the top of the clamps can be completely removed to load terminated fibers. To secure the controller to the optical table, all 2-paddle manual polarization controllers have two clearance slots for M6 cap screws are positioned 25.0 mm apart and two clearance slots for M3 cap screws are positioned 40.0 mm apart on the base for mounting the controller to an optical table.
