MACSEA secures order for Fiber Optic Rotary Joint

This order for the FORJ 291, a MOOG Focal Technologies product, to one of our ROV customers, demonstrates MACSEA’s capability to supply critical parts with efficiency and cost effectiveness in Brazil.

As such, it is part of the scope of supply of our Slip Ring maintenance and repair services, that are currently carried out at our new workshop facilities strategically located in Santa Rita do Sapucai, south region of Minas Gerais.

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.


  • 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 replacement
  • Rugged design
    • MIL-STD-167-1 ship vibration
    • MIL-STD-810 functional shock (40g)


  • Can be integrated into existing slip ring designs
  • Passive bidirectional optical transmission

MACSEA Completes Sistac ROV Upgrade Project

The MACSEA team of the ROV SAAB Seaeye Tiger upgrade project has successfully delivers the system to the customer.

The main objective of the project was to change the characteristics of the vehicle in order to improve its performance, through the interface of a new motion sensor (TOGS), exchange of its data multiplexing system (Focal 907) to interface a new video device (HD IP Camera), increase its operating capacity in low light environments with the addition of two more LED lights to the vehicle. In addition to these upgrades described above, the telemetry of the vehicle and its navigation sensor (Sonar Super SeaKing DST) will operate via fiber optic link.
