Improvements In Human And Environmental Well-being




As Featured In:

Princetel is a for-profit enterprise that applies commercial strategies to maximize improvements in human and environmental well-being.The company’s management is passionate in providing a sanctuary for its employees, creating the best products, offering its customer exceptional services, and maintaining a low carbon footprint.

Bucking the current trend, the company manufactures fiber-optic rotary joint and electric slip-ring products in its US facilities and markets them around the world, including emerging economies such as India, China, and Russia.


The company has attracted a loyal following from customers around the world in markets such as military, biomedical, wind energy, geophysical, broadcasting, robotics, mining, machinery, entertainment, and communications.

Founded in the fall of 2000, the company has become a reliable force in optical and electric rotary technology innovations. Princetel’s successful line of fiber-optic 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 such as 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.

In 2016 Princetel acquired the Wendon Company of Stamford, Connecticut, a slip-ring maker that dates back to the 1950s.

The new alliance is now capable of satisfying the need for power in some very important applications. Princetel also collaborates with numerous partner companies to develop a broad range 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 slip rings are integrated products in applications where both power and telemetry pass through the rotation junction.

To complete the circle in a fiber circuit, Princetel developed a line of highly integrated fiber media converters. They are ideal for ROVs and other robotic vehicles.

Standard video, serial data, high definition video (3G-SDI), gigabit Ethernet, and CWDM solutions are among the standard offerings.

Princetel also provides custom configurations so a mixture of media converters are bundled together on one or multiple fibers.


Princetel’s award-winning fiber polishers offer our customers a convenient tool to terminate fibers in their own facilities.They meet both field and production needs for fiber connector and ferrule polishing.

Our portable polishing machines (up to 2 connectors/ferrules) come with either a unique hand crank or a 6-12 VDC motor, which can be powered through a wall adapter or car cigarette lighter.

The production polishing machine (up to 12 connectors/ferrules) features stainless chassis, center pressure, digitally controlled speed/force/time, speed/force ramping, and universal fixture.

Princetel sets for itself high standards on ethics. We believe in long-term mutually beneficial relationships with our customers, vendors, and employees.

Our design philosophy reflects the company’s strong belief in advanced functionality, reliable performance, contemporary styling, pleasant ergonomics, lean manufacturing, and environmental sustainability.


Our headquarters operation in Hamilton, New Jersey, resides in a LEED Platinum certified building, the only industrial building with that rating in the state of New Jersey.

The positive energy resulting from the unique company culture has rewarded the company with

• A highly diversified (17 different countries) and stable workforce (less than one [1] voluntary departures every four [4] years);
• A very loyal customer base;
• A reliable vendor and service provider network;
• A steady and healthy growth (25% compounded annual revenue growth since 2005).

Princetel is on-track for another decade of dynamic growth and exciting social engagement.
