METHOD, DEVICE AND SYSTEM FOR TESTING OPTICAL NETWORK

摘要

The embodiments of the present invention disclose a method and a device for testing an optical network which are applied to an integrated Optical Time Domain Reflectometer (OTDR), relate to the field of optical network technology and solve the problem of prior art that an Optical Network Unit (ONU) will restore to the initial state when the integrated OTDR tests. The method includes: acquiring the maximum test time of a single group test (901); when total test time is greater than the maximum test time of the single group test, dividing the total test time into at least two groups of single group test time which is not greater than the maximum test time (902); performing the single group tests in turn according to each single group test time (903); instructing the optical network device to restore to the normal work state when the single group test time corresponding to each single group test ends (904). The embodiments of the present invention mainly are used for optical network devices such as an Optical Line Terminal (OLT) integrated with an OTDR.
