[0033] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model. It should be explained that, in the application, in order to facilitate description, the "left side" is "first end", the "right side" is "second end", the "upper side" is "first end", and the "lower side" is "second end" in the current view. The purpose of such description is to clearly express the technical scheme, and should not be understood as improper limitation on the technical scheme of the application.
[0034] The utility model solves the technical problem that an intelligent monitoring device for optical cable is lacked in the prior art to give more perfect monitoring information, so as to facilitate troubleshooting, and provides the communication optical cable intelligent monitoring device, please refer to Figure 1 The specific configuration includes:
[0035] First of all, it needs to be pointed out that: using, for example, optical power meter or optical power detection or monitoring method belongs to the pre-implementation of the present scheme, the same as the prior art, therefore, the present application will not be elaborated, the technical scheme mainly diagnoses the fault point generated by the optical cable itself involves more physical fault points;
[0036] In the implementation configuration, the technical scheme adopts a first optical switch 10, one end of which is connected to the optical cable 1 to be tested, and the other end of which is connected to the LC interface of the first OTDR monitoring module 100.
[0037] The second optical switch 20 has one end connected to an idle optical cable bundle 2 in the optical cable 1 to be tested through an auxiliary jumper 30, and the second optical switch 20 is connected to the LC interface of the second OTDR monitoring module 200.

[0039] The advantage of the technical scheme is that different data are obtained by monitoring the idle optical cable bundle 2 and the optical cable 1 to be tested respectively, and the optical cable 1 to be tested is more likely to produce more events on the actual monitoring curve than the idle optical cable bundle 2 when monitored by the OTDR monitor. The event specifically refers to the stepped curve shown in the curve of the OTDR monitor obtained, such as the bending position and the displacement position. The main event is the fixed peak-valley style curve graph of the connection position. As the monitoring proceeds, the change of the optical cable 1 to be tested will become more obvious over time.
