Fiber Optic Rotary Joints (FORJ) Sealed high performance fiber optic rotary joint Description The FO197S is a sealed single-pass multimode fiber optic rotary joint (FORJ) which is passive and bidirectional, and allows the transfer of analog or digital optical signals across rotational interfaces. The FO197S is specially designed for durable, corrosion free use when exposed to harsh outdoor environments. The FO197S FORJ is constructed of all stainless steel components and is environmentally sealed to an ingress protection rating of IP67. It can be combined with Moog electrical and/or fluid slip rings, providing a single, complete package for optical signals, electrical power, and fluid transfer over a rotating interface. This FORJ is assembled with either bulkhead connectors for fiber pigtails and connectors to suit the application. Housing, mounting flange, and drive features can be customized to meet specific customer requirements. Features • Passive bidirectional optical transmission • Rugged design with IP67 rating, MIL-STD-1 Ships vibration and MIL-STD-810 functional shock (40 g) • Bulkhead connector and Pigtailed versions available • Low optical insertion loss options for common sensor wavelengths • High return loss (i.e. low back reflection) available • Can be combined with Moog electrical slip rings and fluid unions • Can be integrated into existing slip ring designs Typical Applications • Pitch control data for wind turbines • Winches and cable reels for optical sensor systems - Distributed Temperature Sensing (DTs) - Temperature Point Sensor Arrays (TPSA) using Fiber Bragg Gratings (FBG) - Distributed Acoustic Sensing (DAS) • Sensor systems for helicopter rotor blades • Optical Coherence Tomography (OCT) Benefits • Environmentally sealed design allows for long-life in rugged installations and reduces maintenance costs • Low back reflection and insertion losses allow for FORJ integration with very sensitive optical sensor measurements systems Moog Components Group, Halifax Operations 77 Frazee Avenue, Dartmouth, Nova Scotia, Canada B3B 1Z4 • 888-302-2263 • +1-902-468-2263 • Fax +1-902-468-2249 www.moog.com
