Our advantage
1. Product advantage: A single-channel multimode fiber optic rotary joint (FORJ), is passive and bidirectional, and maintain the benefits of fiber optics (such as high bandwidth and EMI immunity) in systems with a rotational interface. This cost-efficient FORJ model is designed for applications having moderate demands for optical performance and life. Due to its lens-less design, it can operate at any wavelength supported by the fiber used in the assembly. The FORJ can be combined with our electrical and fluid slip rings, giving a single, compact package for optical signals, electrical power and fluid transfer.
Features and Benefits
Provides rotary coupling for a multimode fiber link
Can be combined with our electrical slips and fluid unions
Alternative drive coupling and mounting arrangements are available (consult factory for specification details)
Connectorized interfaces, for easy fiber cable replacement
Can be integrated into existing slip ring designs

Factory Scene


Application Filed
The Fiberoptic Rotary Joint (FORJ) is the optical equivalent of the electrical slip ring. It allows uninterrupted transmission of an optical signal while rotating along the fiber axis. The FORJ is widely used in missile guidance systems, robotic systems, remotely operated vehicles (ROVs), oil drilling systems, sensing systems, medical devices (OCTs), broadcasting and many other field applications where a twist-free fiber cable is essential.
