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.

Features

• 2 to 9 singlemode channels
• Can be combined with our electrical slip rings, fluid rotary unions and the model 190 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
• Aluminum and stainless steel construction
• Connectorized interfaces, for easy fiber cable replace-ment
• Rugged design
