Subsea rotary joint FO291

multi-channelfiber optic

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 FO190 to include up to 19 multimode passes. Features 2 to 9 singlemode channels Can be combined with our electrical slip rings, fluid rotary 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 Aluminum and stainless steel construction Connectorized interfaces, for easy fiber cable replacement Rugged design - MIL-STD-167-1 ship vibration - MIL-STD-810F functional shock (40g)
