FO286

FIBER OPTIC ROTARY JOINT


The FO286 (single-pass, multimode) is passive and bidirectional, and allows the transfer of optical signals across rotational interfaces. This model also offers other benefits of fiber optics, including low spark hazard.

With a body diameter of only 9.4 mm and length 21 mm the FO286 unit is ideally suited to applications where size and weight are critical issues.

The FO286 can be combined with our electrical and/or fluid slip rings, providing a single, compact package for optical signals, electrical power and fluid transfer.

Features

  • Provides rotary coupling for a singlemode or multimode fiber link
  • Passive bidirectional device
  • Alternative drive coupling and mounting arrangements are available (consult factory for specification details)
  • Stainless steel, aluminum or anodized aluminum housing
  • Rugged design
    • MIL-STD-167-1 ship vibration
    • MIL-STD-810F functional shock (40 g)

Benefits

  • Can be integrated into existing slip ring designs
  • Passive bidirectional optical transmission
  • Can be combined with our electrical slip rings and fluid unions, as well as Moog Focal's digital fiber telemetry solutions
  • Long life
