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.
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
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.
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 provide custom configurations so a mixture of media converters are
bundled together on one or multiple fibers.
Princetel's award-winning fiber polishers offers 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 an unique
hand crank, an indispensable safety feature to eliminate
fire hazards in oil and gas operations, 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
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. The company is poised to
leap forward in the coming years to refine and expand its product
offerings to serve the growing market.
