| FORJ: Multi-channel fiber optic rotary joint (RJn series, SM & MM) |
|
|
Multi-pass Fiberoptic Rotary Joints (FORJs) connect 3-19 independent fiber channels simultaneously.
They allow uninterrupted transmission of optical signals while rotating along the common mechanical axis.
The RJn series FORJs feature unmatched crosstalk performance (>50 dB) for singlemode fibers.
All channels can accommodate either singlemode or multimode fibers. It is also possible to combine the two types of fibers in one device.
