Optical Slip Ring of 1 Channel with IP65 High Protection Level
Description
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. The Fiber optic 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.
Technology
A quick patent search produces hundreds of inventions around two-channel and multiple-channel fiberoptic rotary joints. Commercially, however, only a limited number of design principals are implemented. At Princetel, we use our proprietary technologies to facilitate both the dual-port (2-channel) and multiport (multi-channel) FORJs. We offer our customers an exciting new alternative to better performance.
