(3) If the absolute D-S is less than or equal to 10 meters, then
The feedback decision information "loss high at test event n, please check reason", when +.>
Then feedback the judging information of 'newly added test event n, please check the reason';
(4) If |D-S| > 10 m, and |D-S m And m is 1 to K and is less than or equal to 10 meters 1 If the test wavelength is 1310 nm or 1550 nm, if |D-S| > 10 m, and |D-S m I > 10 m, where m has a value of 1 to K 1 The feedback decision information "core break at distance from test point D, core break at non-event).
6. The intelligent evaluation system for optical cable operation situation according to claim 1, wherein the network management monitoring data comprises ALOS alarm state information, optical port optical power, real-time service core loss;
the history test data comprises a limit value B of the working range of the light receiving power of the light port 1 、B 2 Wherein B is 2 >B 1 The limit value of the working range of the optical power of the optical port is determined by the specification of an optical module, the total length S, the total loss P and the event number K 1 Event loss p m Distance of event S m Wherein m has a value of 1 to K 1 Is a positive integer of (2);
the second data comparison processing specifically comprises the following steps:
(1) When the I H-S I is less than or equal to 0.2dB, and B 1 ≤G≤B 2 The real-time service fiber core situation of the tested optical cable is judged to run normally, and when the I H-S I is less than or equal to 0.2dB, and B is 1 ≤G≤B 2 The feedback judgment information of abnormal real-time service fiber core loss, please check the reason;
(2) When G is less than B 1 When the feedback judgment information is that the light receiving power of the light port is too low, please check the running state of the fiber core of the real-time service, when G is more than B 2 The feedback judgment information is that the light receiving power of a real-time service fiber core light port is too high, and the reason is checked;
(3) When detecting ALOS alarm, feedback the judging information of losing optical signal, please check the real-time service fiber core interrupt state.
