1, fiber failure and potential faults Real-time Alarm positioning function (fault point GIS is location, sound alarm, SMS notification maintenance person automatically, reaches urgent formula maintenance effects);
2, optical cable total losses, optical cable attenuation rate, case point location are analyzed and exported to circuit transmission state deterioration analytic function (.Reach the preventive maintenance effects);
3, multiple test function (alarm test, the test of artificial point, periodically test.Possess automation remote test and artificial roll-call remote testing effect);
4, lightguide cable link resource management function (reaching visual line resource management effect in conjunction with GIS, topological diagram etc.);
5, every section light path is carried out function of statistic analysis such as fault, alarm;
6, System self-test self-test function (system equipment is taken the post as why to hinder automatic short message is notified).
It is emphasized that; embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model comprises and is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other execution modes that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
