Princetel’s successful line of fiberoptic rotary joints has grown to cover more than a dozen models and three dozen channels in one device. Fiber channels from 1 to 36 remain the standard offerings. They can be either SM, MM fiber, or the mix of the two. They are designed for rugged environments such as extreme temperatures, humidity, mechanical disturbances, and water submersion (pressure compensation). Fiber optic rotary joints (FORJs) are key coupling devices in winches, robotic vehicles, wind turbines, medical OCT systems, satellite antennae, high-definition broadcasting systems, and submarines. Princetel’s FORJ products are designed to comply with the popular standards Telcordia GR1209 and GR1021 in key areas for reliability. All models meet or far exceed MIL-STD-810G and MIL-STD-167-1A for shock and vibration.

Princetel is a small for-profit social enterprise that applies commercial strategies to maximize improvements in human and environmental well-being. It is passionate in providing a sanctuary for its employees, creating the best fiber rotary joint products, offering its customer exceptional services, and maintaining a low carbon footprint. Bucking the current trend, the company manufactures all its fiber optic rotary joint products in its US facility and markets them around the world including emerging economies such as India, China, Russia, and South Africa. The company has attracted a loyal following from customers around the world in markets such as military, biomedical, wind energy, geophysical, broadcasting, robotic, mining, machinery, entertainment, and communications. Founded in the fall of 2000, the company has become a reliable force in fiber rotary technology innovations.

In order to satisfy the need for power in some applications, Princetel collaborates with numerous partner companies to develop a full line of electrical slip rings to match Princetel’s standard FORJs. Unique features such as water seal, pressure compensation, and explosion proof are available. Hybrid electrical/optical sliprings are integrated products in applications where both power and telemetry pass through the rotation junction.
