الملخص

 

In this paper, a new polarization mode dispersion (PMD) monitoring technique is proposed in optical fiber networks. It is based on converting the two orthogonal polarization modes of the monitored signal to the same state of polarization and then they are coupled together with a phase difference of (180º). The amplitude of resulting pulses is measured which is proportional to the differential group delay (DGD) of the fiber link which describes the PMD of the optical fiber link.

The proposed technique is characterized, compared with other monitoring techniques, by good monitoring range, high sensitivity, no modification of the transmitter, simple scheme, not affected by chromatic dispersion (CD), fast response time and the ability to work with different bit rates without requiring any hardware modification,

VPIphotonics simulator was used to demonstrate the validity of the proposed monitoring technique and to analyze its performance.
