FIBER OPTIC ROTARY JOINT SELECTION GUIDE

www.princetel.com

MODEL RPT, RFC, & RST SINGLE-CHANNEL FORJs
The R series Single-channel (SM or MM) rotary joints offer the most versatile
designs on the market. The rugged body allows fiber pigtail, ST, or FC receptacles on either the rotor side or the stator side. One can configure the package
to fit his need exactly. The standard base models are RPT, RFC, and RST for
pigtails, FC/UPC, and ST/PC receptacles.
The R series features extremely low insertion loss and impressive return loss
performance for both singlemode and multimode fibers. These rugged devices
can operate under arctic temperature environments. All three models are dust
and water tight, suitable for harsh environments. Optional pressure compensation is available with model RPT for underwater applications.

MODEL RPC SINGLE-CHANNEL FORJ w/HIGH PRESSURE RATING
Model RPC series FORJs are designed to offer extreme pressure rating of20,000 psi while maintaining identical optical performance as the RPT series.
900 um Hytrel tight buffer and 2.9 mm armored jacket are standard cablearrangements.
Like the RPT series, the RPC series FORJs offer extremely low insertion loss
and can operate under arctic temperature environments. Standard return loss
spec is 40 dB or higher. 50 dB return loss figure is also available as a customoption.

MODEL MJX SINGLE-CHANNEL FORJ
Princetel broke the record when it released the MJX series Fiber Optic Rotary
Joints (FORJs). They are still the smallest and lightest on the market. They
feature extremely low insertion loss and impressive return loss performance.
These rugged devices can operate under arctic temperature environments.
The standard packages are dust and water tight for harsh environment applications. They are designed to tolerate both occasional water splash and shallow
water (or oil) immersion. Pressure compensation of up to 1,000 psi is available
on this model.

MODEL RFCX SINGLE-CHANNEL FORJ
RFCX series Fiber Optic Rotary Adapters (FORAs) are unique since they havethe identical cross sections and mounting features as their standard adapter
counterparts, sometimes also called bulkheads or mating sleeves. FORAs allow
the fiber to rotate freely while maintaining uninterrupted transmission of opticalsignal. Princetel's FORAs can be pop-in replacement of FC bulkheads.
Princetel's design team successfully transformed the proprietary technology
used in the MJX series FORJs to create the miniature rotary adapters. They arevery rugged, sealed for dust and moisture, and can operate under temperature
extremes. RFCX series FORAs feature extremely low insertion loss and good
return loss performance.

MODEL MJP SINGLE-CHANNEL FORJ
The MJP series FORJs are uniquely designed to distinguish themselves fromother Princetel single-channel FORJs such as the the popular RPT model.
Unlike model RPT, MJP is not fluid filled. It offers higher return loss performance(>55 dB). Start up torque is much lower. It can also accept custom fibers,
primarily fibers with cladding diameter larger than 125 um.

MODEL MJ2 DUAL-CHANNEL FORJ
This dual-pass Fiber Optic Rotary Joint (FORJ) connects two independent fiber
channels simultaneously. It allows uninterrupted transmission of optical signals
while rotating along the common mechanical axis. It is designed to accommodate at least one multimode fiber. The other channel can be either single ormultimode fiber. Princetel's unique design has raised the standard for size andperformance of two-channel FORJs.

MODEL PJ2 DUAL-CHANNEL FORJ FOR PLASTIC OPTICAL FIBER (POF)
Plastic optical fibers (POF) possess a few important characters that make themfavorite choices for certain short-distance fiber optic applications. Their large
cores allow easy light coupling. Termination can be simplified to quick hot knife
cutting or diamond turning. They are bend insensitive and do not fatigue easily.
Princetel's PJ2 series 2-channel FORJ connects two independent fiber channels simultaneously. They are blind-spot free during rotation and are ideal formachine control applications such as SERCOS Interfaces. The rugged design
permits underwater usage. Damaged fibers can be easily replaced without
costly repairs of the FORJ itself.
