Princetel, Inc. Is an US manufacturer of fiber optic inter-connect products. Our four main product lines are fiber optic rotary joints, electrical slip rings, active and passive fiber optic components, and fiber polishing machines. The privately funded company was incorporated in the fall of 2000 in the state of New Jersey and has been experiencing high level growth despite the economic slow down in the early years.

Like most passive fiber components, fiber optic rotary joints (FORJs) need to possess the following characters to be effective in a demanding system: low insertion loss, high return loss, low crosstalk, and high reliability. Small size and light weight are often among the key factors. Princetel's FORJ products meet or exceed the most stringent industrial requirements such as Telcordia GR1209 and GR1021 in all mentioned areas. Princetel also offers hybrid electrical / optical slip rings / rotary joints.

Fiber coupling transforms the non-circular beams of diode lasers and facilitates a flexible guide of optical beams. Princetel is capable of coupling up to 4 diode laser beams into a single fiber. Our passive components are as unique as active ones. Fiber collimators can produce output beams from 70 um to 15 mm in diameter. Faraday rotator mirrors with extremely low secondary reflection and high-performance fiber "U" brackets are part of the this product group.

Princetel's fiber polishing machines cover both field and production needs for fiber connector and ferrule polishing. Our field polishing machine has an unique hand crank, eliminating the need for electrical power. It is also a indispensable safety feature in inflammable environments. The motorized version can be powered by either wall power or car outlet. Adjustable force ensures a consistent dome finish. Universal fixture holds up to 3 connectors. The top of the line fiber polishing machine features low body profile, small footprint, speed ramp, and a universal fixture that holds up to 12 connectors. Speed, force, and polishing time are conveniently dialed with separate digital displays.

Princetel sets for itself high standards on ethics, product quality, and customer service. We believe in long-term relationships with our customers, vendors, and investors. Our design philosophy reflects the company's strong belief in advanced functionality, modern styles, pleasant ergonomics, and environmental sustainability.
