Automatic Rotating Fiber Holder / FHRA

The rotary fiber holder is used to rotate and adjust the polarization plane of polarization-maintaining fiber. This fiber holder is attached to the holder mounting part of the alignment unit and requires the FHRA-BP (sold separately).

We have two types of fiber holders: the FHRAW series with a suction function at the tip and the FHRA series without a suction function. We also have three jacket diameters of 250 μm, 400 μm, and 900 μm. All cladding diameters are specified at 125 μm

A magnetizing bolt is built into the plastic holder, and the magnetic force of the fiber holder's magnet gently clamps the polarization-maintaining fiber.
The fiber retention part can be removed by a magnet.
By using the auto-rotating fiber holder fixing plate (FHRA-BP), this fiber holder can be incorporated into the DAU-8100A series alignment unit.
When removing the fiber retention unit, please do so at the 0 degreeposition. In addition, a vacuum pump is required to use the suction mechanism. Please contact our sales department for information on vacuum pump peripheral equipment.
