Multi-Channel Fibre Optic Rotary Joint - JXn Series from Princetel

JXn series multi-pass Fibre optic Rotary Joints (FORJs) accommodate 3-12 independent fibre channels as standard options. 13-60 channels are offered on custom basis. Loss and back reflection are uniform across all channels. There is no channel "drop off" or "blind spot" during rotation. They feature low crosstalk performance (<-60 dB) for both single and multi-mode fibres.

The JXn series fiber optic rotary joints share the same body diameter and mounting schemes with MJn series FORJs. However, the JXn design makes it more convenient to integrate with electrical slip rings. Pressure compensation is available as an option. Like our other multi-channel FORJs, all channels can accommodate either singlemode or multimode fibres. It is also possible to combine the two types of fibres in one device across three optical windows (850, 1310, and 1550 nm).
