RPT Single Channel Optical Fiber Rotary Joint(OFRJ)







Interpolation/Temperature Cycle Curve



Return loss/temperature cycle curve



     The delicate R series single channel optical fiber rotary joint has a variety of packaging  types. It can be either optical fiber connection or FC or ST socket connection at the  rotating or stationary ends. There are nine combinations to meet your system needs.   

     R series optical fiber rotary joint has the characteristics of low insertion loss and high  return loss. The return loss of RPTA type is as high as 60 dB. It can work in extreme high and low temperature and harsh environment. RPPC with pressure compensation can work in shallow water.

     The insertion loss and return loss of all optical fiber rotary joints are accomplished by optical fiber fusion. That is to say, the additional value of optical fiber connector is not  included in the test data.
