For example, the module 17 for indicating whether the detection device is connected to the cable to be detected may include, but is not limited to, a status indicator light or a status indicator screen.

For example, the SFP optical modules at each end of the active fiber optic cable may be plugged into the fiber optic interface of the detection device, which may include, but is not limited to, an SFP interface.
For example, the PON optical module at each end of the passive optical fiber cable may be plugged into an optical fiber interface of the detection apparatus, which may include, but is not limited to, an optical Fiber Connector (FC) or a pass-through optical fiber Connector (ST), etc.
For example, the Active fiber optic cable may include, but is not limited to, an Active Optical Cable (AOC).
Preferably, after the switch of the power supply module 35 in the detection device is turned on, the power supply module 35 may output electric energy to the programmable logic chip 30 and the interface chip 31, respectively, so that the programmable logic chip 30 and the interface chip 31 may be powered on to operate.
Preferably, the interface chip 31 can determine whether the detection device is communicated with the cable to be detected, if so, the interface chip 31 sends an electrical signal capable of indicating the communication to the module 37 for indicating whether the detection device is communicated with the cable to be detected through the programmable logic chip 30, and then the module 37 for indicating whether the detection device is communicated with the cable to be detected sends a communication success indication signal according to the electrical signal. On the contrary, if there is no connection, the interface chip 31 may send an electrical signal capable of indicating the disconnection to the module 37 for indicating whether the detection device and the cable to be detected are connected or not through the programmable logic chip 30, and then the module 37 for indicating the connection between the detection device and the cable to be detected sends a disconnection indicating signal according to the electrical signal.
For example, the module 37 for indicating whether the detection device is connected to the cable to be detected may include, but is not limited to, a status indicator light or a status indicator screen.
For example, if the status indicator light is orange, it indicates that the detection device is connected to the cable to be detected. If the status indicator light is not bright, the status indicator light indicates that the detection device is not communicated with the cable to be detected or the cable to be detected which is physically connected with the detection device does not exist.
For example, if the information displayed on the status indicator screen is 00, it indicates that the detection device and the cable to be detected are connected. If the information displayed by the state indicating screen is 11, the state indicating screen indicates that the detection device is not communicated with the cable to be detected or the cable to be detected which is physically connected with the detection device does not exist.
For example, the principle that the detection device detects the cable in the embodiment of the present invention is as follows:
as shown in fig. 2, the conversion module 21 of the cable to be detected, which is communicated with the detection device, can receive the optical signal sent by the detection device (the detection device 1 in fig. 2) at the opposite end through the cable to be detected.
As shown in fig. 2, the conversion module 21 converts the optical signal, and then transmits a third electrical signal obtained by the conversion to the module interface 32 in the detection apparatus.
As shown in fig. 3, the module interface 32 receives the third electrical signal from the conversion module 21.
As shown in fig. 3, the module interface 32 outputs the third electrical signal to the interface chip 31.
As shown in fig. 3, the interface chip 31 outputs a fourth electrical signal obtained by processing the third electrical signal to the programmable logic chip 30. For example, the fourth electrical signal may be a count value of the message obtained by the interface chip 31 counting the received message.
As shown in fig. 3, the programmable logic chip 30 outputs the processed fourth electrical signal to the module 33 for indicating the detection result. For example, the programmable logic chip 30 reads the count value of the message from the interface chip 31 at a preset reading frequency, and then outputs a corresponding indication electrical signal to the module 33 for indicating the detection result according to the count value.
For example, the read frequency may be read once in 5 seconds.
As shown in fig. 3, the module 33 for indicating the detection result sends out a detection result indicating signal of the cable to be detected.
For example, the module 33 for indicating the detection result may include, but is not limited to, a detection result indicating lamp or a detection result indicating screen.
Taking the module 33 for indicating the detection result as the detection result indicator light as an example, if the count value of the message is 0, the programmable logic chip 30 outputs an electrical signal 1 to the detection result indicator light, and the detection result indicator light is displayed as green. If the count value of the message is not 0, the programmable logic chip 30 calculates a Cyclic Redundancy Check (CRC) ratio according to the count value of the message, and if the CRC ratio is greater than 10-9The programmable logic chip 30 outputs an electric signal 2 to the detection result indicator light, and the detection result indicator light is displayed in red. If the CRC ratio is less than or equal to 10-9And the programmable logic chip 30 outputs an electric signal 3 to the detection result indicator lamp, and the detection result indicator lamp is displayed as green flashing. Therefore, according to the signal sent by the module 33 for indicating the detection result, the CRC ratio of the transmission packet of the cable to be detected can be obtained, and the performance detection result of the cable to be detected can be obtained.
In addition, when the cable to be detected is detected again, the interface chip 31 automatically clears the original count value.
For example, the power supply module 35 may include, but is not limited to, a battery.
For example, the module 36 for indicating the power amount provided on the power supply module 35 may include, but is not limited to, a power amount indicating lamp or a power amount indicating screen.
For example, if the power indicator light is displayed as green, it indicates that power is being supplied to the programmable logic chip 30 and the interface chip 31 normally, and the power of the power supply module 35 is sufficient. If the electric quantity indicator light is displayed in red, it indicates that the electric quantity of the power supply module 35 is lower than a certain threshold. If the power indicator light goes off, it indicates that power supply to the programmable logic chip 30 and the interface chip 31 is stopped, and the power supply module 35 consumes power.
For example, the power indication screen may display the current remaining power information of the power supply module 35, such as a specific value of the remaining power or a percentage of the remaining power.
