Measuring differential group delay in an optical fiber |
摘要 |
A system includes an optical transmitter configured to generate an optical signal that includes a scrambled polarization state; and output the optical signal via an optical fiber associated with a network path that is transporting network traffic. The system also includes an optical receiver configured to receive the optical signal; measure a polarization associated with the optical signal; determine, based on the polarization, a degree of polarization associated with the test signal; identify a differential group delay associated with the test signal based on the degree of polarization; output a notification that the optical fiber is available to carry high capacity traffic when the differential group delay is less than a threshold, where the high capacity traffic includes a data rate that his greater than another threshold; and output a notification that the optical fiber is not available to carry the high capacity traffic when the differential group delay is not less than the threshold.
