Fiber Optic Rotary Joints (FORJ)
For more than 20 years, FOCAL has focused on the rotary interface needs of the marine and energy industries. Today, their fiber optic rotary joints (FORJs) are recognized around the world for innovative performance and reliability in harsh marine environments.

Experienced Innovators
Their reputation for innovation grew when they were the first to develop FORJs for marine applications. Today, we are still recognized as industry leaders. As the developers of the first commercial multi-pass, multimode and singlemode FORJ, as well as a collection of features responsive to the needs of the marine and energy industry, we are continually setting new standards. The Model 291, for example, allows up to 9 passes in a housing less than 2.5 inches (6.4 cm) in diameter. Recent product development also includes a variety of single and multiple channel devices for singlemode applications.

Outstanding Reliability
We design for demanding conditions. Rigorous testing of every FORJ is performed in our own environmental testing chambers and the facilities of testing specialists. Standard features, such as connectorized interfaces that allow for easy replacement of damaged pigtails, are designed to minimize down time. Our engineers have the resources to design for performance reliability in unique environmental conditions such as subsea depths of more than 18,000 feet (5.5 km), high altitudes for aerospace applications or extreme temperature conditions. We can also design for extra-long life or higher than average speeds.
