The FO291 is a multi-pass, singlemode fiber optic rotary joint (FORJ). It is passive and bidirectional, and allows the transfer of optical signals across a rotational interface on 2 to 9 separate singlemode optical fibers.
The FO291 can be combined with our electrical and / or fluid slip rings, giving a single, compact package for optical signals, electrical power and fluid transfer, with ISO 9000 quality.
Other options include fluid-filling for pressure compensation permitting operation at any ocean depth, and the combination of the model 190 to include up to a total of 19 multimode passes.
Suitable for operation over full CWDM band (18 wavelengths from 1271nm to 1611nm in 20nm increments), tested at 1310nm and/or 1550nm. Consult factory for other wavelengths such as 900-1100nm band (tested at 1060nm)
To 100 rpm dry and 60 rpm fluid filled. Consult factory for higher rotational speeds
-40° to +60° C standard. Consult factory for extended range
Stainless steel and aluminum
40 g / 11 ms sawtooth per MIL-STD-810 Method 516
FC / PC connector bushings standard (ST connector bushings optional)
Up to 10,000 psi (69,000 kPa) for fluid filled version
