Technical Description
These fiber system components are ideal for constructing various fiber optical systems. Our fiber stages support both simple single-axis and complex multi-axis setups. They minimize displacement caused by vibration and temperature variation, ensuring long-term optical path stability.



Fiber wall plates can be mounted on the side of the stage using two included M4 screws. Wall plates feature SM1 or SM05 internal threads; with fiber adapters, they support FC/PC/APC or SMA connectors. They are compatible with lens sleeve series and SM-threaded components. FWP-05 and FWP-X05 wall plates include cage rod mounting holes for integrating fiber systems with cage systems, expanding application flexibility.
| Model | Internal Thread | Cage Compatibility |
|---|
| FWP-05 | SM05 (0.535-40) | 16 mm |
| FWP-X05 | – | 16 mm, 30 mm |
| FWP-1 | SM1 (1.035-40) | / |


- Oeabt offers various component mounts for fiber stages to install diverse optical elements. All modules have locating dowel pins that precisely fit mounting holes on the fiber stage, keeping the optical beam height fixed at 14.3 mm. This enables easy interchange and alignment of different accessories, simplifying optical path setup.
