R-FORJ Series

Fiber Optical Rotary Joint

The R series Single-channel (SM or MM) rotary joints offer many variations. The rugged body allows fiber pigtail, ST, or FC receptacles on either the rotor or the stator side. There can be total of nine different configurations to fit the need exactly.

The standard base models are RPT, RFC, and RST for pigtails, FC/PC, and ST/PC receptacles. Similar to MJX and RFCX series, the R Series FORJs contain fluid, which ensures condensation-free operation at extremely low temperatures. It is also ideal for high-humidity environments. The R series features extremely low insertion loss and impressive return loss performance for both singlemode and multimode fibers.

Model RPTA typically yields return loss figures higher than 60 dB. These rugged devices can operate under arctic temperature environments. All models are dust and watertight for harsh environments.

Note: All insertion loss and return loss measurements are performed by joining the FORJ to the light source through a fusion splice (without the use of connectors). Insertion loss of all receptacle types of FORJs, such as RST, RFC, and RFCX, are measured with connectors of similar type. Their return loss is not measured.
