It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The light conversion equipment provided by the embodiment of the application is suitable for the technical field of optical fiber communication and testing, and particularly relates to communication and testing technologies in the fields of aerospace and military industry.

In the prior art, for FC communication devices (hereinafter, may be referred to as FC coaxial devices) with coaxial ports, during a communication test, the FC communication devices need to be connected with a test device through a light conversion device; when a transmission index test (for example, a rise/fall time test, a transmission eye pattern test, a jitter test, and the like) of a coaxial interface of the FC coaxial device is performed, a short coaxial cable (for example, 0.5 m) may be used to connect with the light conversion device, and then the light conversion device and the test device are connected by an optical fiber line; when a receiving index test (such as receiving level, jitter, receiving eye pattern, etc.) of the coaxial interface is performed, a long coaxial cable (such as 30 meters, even 40 meters, etc.) can be used to connect the FC coaxial device and the optical conversion device, and further connect the optical conversion device and the test device through an optical fiber line.

It should be noted that the length of the long coaxial cable can be flexibly selected according to the receiving sensitivity of the coaxial interface, and if the receiving sensitivity of the coaxial interface is exactly within the boundary of the index, the attenuation of the coaxial cable needs to be relatively precise, so that the length control of the coaxial cable is required to be relatively high and is relatively troublesome, and the coaxial cable is relatively expensive. Therefore, for such a situation, a mode of externally connecting an adjustable attenuator can be adopted to replace the attenuation effect of the long coaxial cable, that is, the short coaxial cable and the adjustable attenuator are adopted to connect the FC coaxial device and the light conversion device; in addition, according to the attenuation granularity of the existing adjustable attenuator, the adjustable attenuator can be divided into a coarse adjustable attenuator (the attenuation granularity is 1 dB) and a fine adjustable attenuator (the attenuation granularity is 0.1 dB), based on which, the test topology of the coaxial interface of the FC coaxial device can be as shown in fig. 1, wherein, one coaxial interface of the FC coaxial device is connected with one coaxial port of the optical switching device sequentially through the coarse adjustable attenuator and the fine adjustable attenuator, and then, one optical port of the optical switching device is connected with one optical port of the test device through an optical fiber line; the FC coaxial equipment is provided with a plurality of coaxial interfaces, and a plurality of coarse-adjustment adjustable attenuators and fine-adjustment adjustable attenuators need to be connected, so that too many external equipment need to be introduced in the test process, the test cost is high, the test process is too complicated, and the test efficiency is low.

Therefore, the embodiment of the application provides a light conversion device, the FC communication device to be tested and the test device can be directly connected through the light conversion device, signal receiving and signal sending tests are performed on the FC communication device to be tested, no additional external device is needed to be added, the test cost can be reduced, the test process is simplified, and the test efficiency of the FC communication device can be further improved.

Optionally, the processor 11 may determine attenuation values corresponding to the target light conversion module and the target light conversion module according to a magnitude relationship between a target attenuation value input by a user and an attenuation value threshold of the light conversion module to be configured; it should be noted that, due to the performance difference of the light conversion modules, the attenuation ranges that can be realized by each light conversion module may be the same or different, that is, the attenuation value thresholds of each light conversion module may be the same or different. Inside the processor 11, an attenuation value threshold corresponding to each light conversion module may be preset.

Alternatively, in a case that it is determined that the target attenuation value is not greater than the attenuation value threshold of the light conversion module to be configured, the processor 11 may determine that the light conversion module to be configured is the target light conversion module, and may use the target attenuation value as the attenuation value to be configured corresponding to the target light conversion module.

TABLE 1

The following describes a specific example of the channel selection port setting and the transmission channel of the test signal in the cascade and non-cascade states.

For example: when the user selects to test the signal of channel 1, the user selects button 1 via port select button U6 to instruct the MUC to set attenuation chip 1 to attenuation mode (i.e. control IOC1 port output high, OE =1 for attenuation chip 1); next, the user inputs a target attenuation value corresponding to the attenuation chip 1 through the attenuation setting button U7; assuming that the target attenuation value input by the user is less than or equal to the preset threshold of the attenuation chip 1, the MCU controls the channel selection signals of the attenuation chip 1 to be 000 (i.e., 1_ RX1 → 1_ TX 1) and 100 (i.e., 2_ RX1 → 2_ TX 1), that is, the test signal is transmitted through the attenuation chip 1, the coaxial transformer 1 and the FC optical module 1.

Assuming that the target attenuation value input by the user is greater than the preset threshold value of the attenuation chip 1, the MCU controls the channel selection signals of the attenuation chip 1 to be 001 (i.e., 1_ RX1 → 1_ TX 2) and 110 (i.e., 2_ RX2 → 2_ TX 1) and controls the channel selection signals of the attenuation chip 2 cascaded with the attenuation chip 1 to be 010 (i.e., 1_ RX2 → 1_ TX 1) and 101 (i.e., 2_ RX1 → 2_ TX 2), that is, the test signal is transmitted through the attenuation chip 1, the attenuation signal 2, the coaxial transformer 2 and the FC optical module 2. Meanwhile, the MCU determines a first attenuation value to be set of the attenuation chip 1 and a second attenuation value to be set of the attenuation chip 2 according to a target attenuation value input by a user and a preset threshold value of the attenuation chip 1; optionally, the first attenuation value to be set may be a preset threshold of the attenuation chip 1, and the second attenuation value to be set is a difference value between a target attenuation value input by a user and the preset threshold of the attenuation chip 1; the first attenuation value to be set and the second attenuation value to be set can be one half of a target attenuation value input by a user; the distribution mode of the attenuation values to be set of each cascaded attenuation chip is not limited in the application. After determining the first attenuation value to be set and the second attenuation value to be set, the MCU may control the attenuation chip 2 to be in the attenuation mode, that is, control the IOC2 port to output a high level, so that OE =1 of the attenuation chip 2; next, attenuation values of the

attenuation chips

1 and 2 may be set, respectively.
