001 Custom FORJ series multi-pass Fibre Optic Rotary Joints (FORJs) can accommodate 2-8, independent fibre channels as standard options. 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.
This unit is for the ideal to integrate into an electrical slip ring for submerged use. Pressure compensation is standard for the unit and suitable for deepsea operations (6000 meters). 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).
