It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic overall architecture diagram of a monitoring apparatus for fiber core resources of an optical cable according to an embodiment of the present application; fig. 2 is a schematic partial structural diagram of a flange plate of a device for monitoring fiber core resources of an optical cable according to an embodiment of the present application.

It should be noted that, the optical cross-connecting box 100 is a short for optical cable cross-connecting box, and the display unit may be a mobile phone client or a computer client, that is, a user may check the occupation condition of the optical cable fiber core resource in the optical cross-connecting box 100 at any time through the display unit, and does not need to check on site, which is convenient and efficient, and has a function of early warning in advance.

The optical cross connecting box 100 includes a box body 101, and a wireless connection unit 110, an optical fiber coupler, a current sensor 130 and a signal processing unit 140 which are arranged in the box body 101; the wireless connection unit 110 is used for communication connection between the optical junction box 100 and the display unit; the optical fiber coupler comprises at least one flange plate 121, wherein the flange plate 121 is used for being connected to the fiber core of the optical cable to close a circuit and generate a current signal; one end of the current sensor 130 is electrically connected to the flange 121, the other end of the current sensor 130 is electrically connected to the signal processing unit 140, and the current sensor 130 is configured to sense a current signal of the fiber core of the optical cable and transmit the current signal to the signal processing unit 140; the signal processing unit 140 is configured to obtain the occupation information of the fiber core resource of the optical cable according to the current signal, and transmit the occupation information of the fiber core resource of the optical cable to the display unit through the connection unit.

The method is mainly characterized by low speed, low power consumption, low cost, support of a large number of nodes on the network, support of various topologies on the network, low complexity, rapidness, reliability and safety.

It should be noted that the current signal refers to a signal that can be generated after the fiber core of the accessed optical cable forms a closed circuit, and the current sensor 130 senses the current signal and transmits the current signal to the signal processing unit 140, but in an actual application scenario, the optical cross-connect box 100 may be disposed in a place with a severe environment, and at this time, other objects may touch the flange 121 to cause the circuit to be turned on, so that the current sensor 130 obtains an erroneous current signal, and further, misjudgment is caused.

In order to avoid the above problem, the current sensor 130 having a sensitivity adjustment function may be selected, and the current sensor 130 may be enabled to identify the current signal of the core of the optical cable by adjusting a preset sensitivity value of the current sensor 130.

Specifically, because the current that other objects and optical cable fibre core access ring flange 121 produced is of different magnitudes, in view of the above, current sensor can judge whether current signal is the signal that optical cable fibre core produced, only when this current signal is that optical cable fibre core produced, just can trigger current inductor 130 and give signal processing unit 140 with this current signal transmission, and transmit the display element, current inductor 130's preset sensitivity value should be adjusted according to service environment condition and the difference of the current signal that optical cable fibre core produced promptly, make current inductor 130 can discern the occupation condition of optical cable fibre core resource more accurately, avoid producing the condition of wrong report because the perturbation of the environment.

That is, each flange 121 has a plurality of connection ports 1212 for accessing a plurality of fiber optic cable cores, so as to enrich the fiber optic cable core resources of the optical cross connect box 100.

Illustratively, as shown in fig. 2, the current sensor 130 includes a plurality of elastic switches 131, each elastic switch 131 is in contact with one of the connection ports 1212, and the elastic switches 131 can be triggered by a pressing force generated when the connection port 1212 is connected to the core of the optical cable, so as to close the circuit.

It will be appreciated that the resilient switches 131 described above effectively act as probes for the sensor, and that each resilient switch 131 is in contact with one of the connection ports 1212, and that when the connection port 1212 is free of the fiber optic cable core, the resilient switch 131 is in an open state and the circuit is open and free of the current signal. When the connection port 1212 is connected to the core of the optical cable, the optical fiber is screwed into the connection port 1212, thereby generating a certain pressing force on the connection port 1212, which presses the elastic switch 131 in contact with the connection port 1212, thereby closing the internal circuit to generate a current signal.

It will be readily appreciated that if the fiber core of the optical cable is pulled out of the connection port 1212, the resilient switch 131 is restored, and the circuit is disconnected from the current-free signal, and the display unit shows that the connection port 1212 is unoccupied.
