FIBER OPTIC ROTARY JOINT
Legacy product and should not be used for new designs. For new designs, see FO291 product.
The FO242 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 6 separate singlemode optical fibers.
The FO242 can be combined with our electrical and / or fluid slip rings giving a single, compact package for optical signals, electrical power and fluid transfer.
Other options include fluid-filling for pressure compensation permitting operation at any ocean depth, and the combination of the FO190 to include up to 19 multimode passes.
- 2 to 6 singlemode channels
- Can be combined with our electrical slips, fluid unions and the FO190 multimode fiber optic rotary joint
- Alternative drive coupling arrangements are available (consult factory for specification details)
- Tested to 10,000 psi (69,000 kPa) when fluid-filled
- Stainless steel and aluminum construction
- Connectorized interfaces, for easy fiber cable replacement
- Rugged design
- MIL-STD-167-1 ship vibration
- MIL-STD-810D functional shock (40 g)
