The R series Single-channel (SM or MM) rotary joints are the most versatile designs the market has ever seen.
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 FST for pigtails, FC/PC, and ST/PC receptacles.
The R series features extremely low insertion loss and impressive return loss performance for both
singlemode and multimode fibers. Model
RPTA guarantees return loss as high as 50 dB. These rugged devices can operate under arctic temperature environment (See insertion
loss and return loss temperature cycling plots on the left).
All models are dust and water tight for harsh environment. Optional pressure compensation is available with model RPTPC
for shallow water applications.
