In this paper, the general theory and polarization property of RB in single mode fiber is discussed. According to the theoretical analysis results, the bidirectional carrying system with a polarization rotating device for analog radio frequency (RF) signal is set up. The relationship of the system CRN and the different polarization state by the polarization rotating device is studied. The results show that the RB light polarization state of backward fiber end can keep to perpendicular to that of forward light when backward lights polarization is orthogonal forward lights polarization. So utilizing orthogonal polarization method for decreasing CRN can be carried on. The system performance is analyzed by simulation. The simulation results show that CRN of the bidirectional communication system on a single mode fiber can be inhibited by using the method and RB light can decrease by an order of magnitude.

Line System

An in-line all-fiber measurement system for polarization parameters is designed and fabricated in this paper. This system implements accurate control of polarization state, together with in-line, accurate, and high-speed measurement of Stokes vector. It can measure the light polarization parameters such as States of Polarization (SOP), Degree of Polarization (DOP), Light Polarization Extinction Ratio (LPER), and related losses of polarization. Besides, polarization monitoring and stabilizing can be achieved using this system. Because there is no discrete device concluded, the optical path of this system is completely constituted by optical fiber, which makes the entire system low-cost, with small size and low insertion loss.
