OPTICAL FIBER MECHANICAL BEND STRESS TEST SYSTEM WITH OPTICAL TIME-DOMAIN REFLECTOMETER |
摘要 |
Methods and devices provide for storing historical data that includes interference values mapped to at least one of bend radii values, lifetime values, or failure rate values of optical fibers; transmitting an optical signal, via a test system, toward the optical fiber under test; setting a polarization state of the optical signal before the optical signal propagates through the optical fiber under test; setting a polarization state of a reflected optical signal that has propagated through the optical fiber under test in a manner that causes a minimum interference or a maximum interference; measuring instances of power of the reflected optical signal; and outputting a result that includes at least one of a bend radius value, a lifetime value, or a failure rate that applies to the optical fiber under test based on the measured instances of power and the historical data. |

1. A method comprising:
transmitting an optical signal, via a test system, toward an optical fiber under test that has a tight bend; setting a state of polarization of the optical signal before the optical signal reaches the optical fiber under test; setting a state of polarization of a reflected portion of the optical signal that propagated through the optical fiber under test; measuring instances of power of the reflected portion of the optical signal; calculating interference values of the reflected portion of the optical signal based on the measured instances of power; storing interference values mapped to at least one of bend radii values, lifetime values, or failure rate values pertaining to optical fibers; selecting a match between at least one of the calculated interference values and one of the stored interference values; and outputting a result that includes at least one of a bend radius value, a lifetime value, or a failure rate that applies to the optical fiber under test. |
