Description

Technical Field

[0001] The utility model relates to the technical field of optical communication, and in particular to an adaptive performance detection device and an optical module for realizing transmission service imperceptibility. Background Art

[0002] When transmission services in optical communication systems are abnormal, some of the abnormalities are difficult to distinguish whether they are caused by the transmitting device or the receiving device. Such problems can generally be solved by adding a data analysis unit between the transmitting device and the receiving device. The data analysis unit performs performance detection on the signals of the corresponding service type, thereby monitoring the status of the transmission service in real time.

[0003] However, the data analysis unit only performs data analysis on the electrical signals converted from the optical signals of the specified business type, and then monitors the status of the optical signals of the corresponding business type. For optical signals of other business types that the data analysis unit is not compatible with, the data analysis unit cannot perform data analysis and processing on them. The electrical signals corresponding to the optical signals of these business types cannot be compatible and transmitted by the data analysis unit. If the data analysis unit is set on the main line of the business transmission link, the business transmission link can only transmit optical signals of business types that are compatible with the data analysis unit, and cannot transmit optical signals of business types that the data analysis unit is not compatible with. This results in greater limitations on the business transmission link and lower utilization efficiency.

[0044] In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] Embodiment 1:

[0046] Embodiment 1 of the present invention provides an adaptive performance detection device that realizes transmission service without perception, such as Figure 1As shown, it includes: a photoelectric conversion unit 1, a loopback module 2, an electro-optical conversion unit 3 and a data analysis unit 4, wherein:

[0047] The photoelectric conversion unit 1 is connected to the input end of the loopback module 2, one of the output ends of the loopback module 2 is connected to the electro-optical conversion unit 3, and the other output end of the loopback module 2 is connected to the data analysis unit 4; the loopback module 2 is used to mirror the electrical signal to obtain two mirror electrical signals, and send the two mirror electrical signals to the electro-optical conversion unit 3 and the data analysis unit 4 respectively; the electro-optical conversion unit 3 is used to convert the mirror electrical signal into regenerated output light and output it, and the data analysis unit 4 is used to detect the mirror electrical signal of the corresponding business type.

[0048] The photoelectric conversion unit 1 is used to receive optical signals from other optical modules in the outside world, and convert the optical signals into electrical signals, and transmit the electrical signals to the loopback module 2. The loopback module 2 is used to complete the optical regeneration of the input electrical signals corresponding to the transmission service. The electro-optical conversion unit 3 is used to convert the electrical signals output by the loopback module 2 into optical signals to achieve the output of regenerated light. The data analysis unit 4 is used to perform data analysis on the electrical signals output by the loopback module 2, so as to perform performance detection on the input optical signals, monitor whether the optical signals are abnormal through the performance detection, and determine whether the optical signals are abnormal if the optical signals are abnormal, and determine whether the optical signals are caused by the transmitting device or the receiving device.

[0049] It should be noted that since the data analysis unit 4 can only perform data analysis on the electrical signals converted from the optical signals of the specified business type, and then monitor the status of the optical signals of the corresponding business type; and for the optical signals of other business types that the data analysis unit 4 is not compatible with, the data analysis unit 4 cannot perform data analysis and processing on them, and the electrical signals corresponding to the optical signals of these business types cannot be compatible and transmitted by the data analysis unit 4. If the data analysis unit 4 is set on the main line of the business transmission link, the business transmission link can only transmit optical signals of business types that are compatible with the data analysis unit 4, and cannot transmit optical signals of business types that the data analysis unit 4 is not compatible with, resulting in greater limitations on the business transmission link and lower utilization efficiency.

[0050] Therefore, in order to avoid the situation where the service type cannot be normally transmitted on the service transmission link due to the incompatibility of the data analysis unit 4 with the optical signals of some service types, in this embodiment, the electrical signal is mirrored in the loopback module 2 to obtain two identical mirrored electrical signals, and the two identical mirrored electrical signals can represent the optical signal originally input, and the two mirrored electrical signals are respectively transmitted to the electro-optical conversion unit 3 and the data analysis unit 4 through two different transmission paths, and the path transmitted to the electro-optical conversion unit 3 completes the optical regeneration of the corresponding transmission service. For the path transmitted to the data analysis unit 4, if the service type of the input optical signal is compatible with the data analysis unit 4, the data analysis unit 4 performs data analysis and performance monitoring according to the received mirrored electrical signal. If the service type of the input optical signal is not compatible with the data analysis unit 4, the data analysis unit 4 cannot perform performance monitoring on the service type. However, since the electro-optical conversion unit 3 and the data analysis unit 4 are two paths that do not interfere with each other, the optical regeneration of the transmission service on the path where the electro-optical conversion unit 3 is located will not be affected, and the service transmission path can still work normally, thereby increasing the types of compatible transmission services and improving the utilization efficiency of the service transmission link.

[0051] In this embodiment, in order to achieve the effect of processing the electrical signal into two mirror electrical signals in the loopback module 2, this embodiment also involves the following design:

[0052] like Figure 2 As shown, the loopback module 2 includes: a path switching unit 21, a first driving unit 22 and a second driving unit 23, wherein: the path switching unit 21 is connected to the photoelectric conversion unit 1, the path switching unit 21 is connected to the first driving unit 22 and the second driving unit 23 respectively, the first driving unit 22 is connected to the electro-optical conversion unit 3, and the second driving unit 23 is connected to the data analysis unit 4.

[0053] The path switching unit 21 is used to receive the electrical signal from the photoelectric conversion unit 1, and mirror the electrical signal to obtain two mirror electrical signals, one of which is sent to the first driving unit 22, and the other is sent to the second driving unit 23; the first driving unit 22 is used to convert the received mirror electrical signal into a differential signal pair and transmit it to the electro-optical conversion unit 3; the second driving unit 23 is used to convert the received mirror electrical signal into a differential signal pair and transmit it to the data analysis unit 4.

[0054] In this embodiment, the path switching unit 21 is used to mirror the electrical signal to generate two mirror electrical signals; accordingly, the path switching unit 21 can be actively turned on or off. When it is necessary to monitor the performance of the transmission service, the path switching unit 21 is turned on to mirror the electrical signal. If the service type of the current optical signal is incompatible with the data processing unit, the path switching unit 21 can be turned off, and only one transmission path of the electro-optical conversion unit 3 is connected. No service performance monitoring is performed, and only the output of optical regeneration corresponding to the transmission service is completed.

[0055] In this embodiment, since the electro-optical conversion unit 3 and the data analysis unit 4 need to receive corresponding differential signal pairs in actual applications, the first driving unit 22 and the second driving unit 23 are both used to convert the mirror electrical signal into a differential signal pair, and transmit it to the corresponding electro-optical conversion unit 3 and the data analysis unit 4; wherein the differential signal pair includes a first differential signal and a second differential signal, and the first differential signal and the second differential signal have opposite phases and the same amplitude.

[0056] In this embodiment, since the first differential signal and the second differential signal need to be transmitted through different transmission paths, this embodiment also involves the following design:

[0057] like Figure 3 As shown, the first output terminal 221 on the first driving unit 22 is connected to the first receiving terminal 31 on the electro-optical conversion unit 3 , and the second output terminal 222 on the first driving unit 22 is connected to the second receiving terminal 32 on the electro-optical conversion unit 3 .

[0058] In this embodiment, a pair of differential signal lines (which can be conductive lines on a circuit board) can be set between the first driving unit 22 and the electro-optical conversion unit 3, wherein one end of one differential signal line is connected to the first output end 221, and the other end is connected to the first receiving end 31, and the differential signal line is used to transmit the first differential signal in the differential signal pair; one end of the other differential signal line is connected to the second output end 222, and the other end is connected to the second receiving end, and the differential signal line is used to transmit the second differential signal in the differential signal pair.

[0059] The third output terminal 231 on the second driving unit 23 is connected to the third receiving terminal 41 on the data analyzing unit 4 , and the fourth output terminal 232 on the second driving unit 23 is connected to the fourth receiving terminal 42 on the data analyzing unit 4 .

[0060] In this embodiment, a pair of differential signal lines (which can be conductive lines on a circuit board) can be set between the second driving unit 23 and the data analysis unit 4, wherein one end of one differential signal line is connected to the third output terminal 231, and the other end is connected to the third receiving terminal 41, and the differential signal line is used to transmit the first differential signal in the differential signal pair; one end of the other differential signal line is connected to the fourth output terminal 232, and the other end is connected to the fourth receiving terminal 42, and the differential signal line is used to transmit the second differential signal in the differential signal pair.

[0061] like Figure 4 As shown, the adaptive performance detection device that realizes transmission service imperceptibility also includes an amplifying and equalizing unit 5, a receiving end of the amplifying and equalizing unit 5 is connected to the photoelectric conversion unit 1, and an output end of the amplifying and equalizing unit 5 is connected to the path switching unit 21.

[0062] The amplifying and equalizing unit 5 is used to amplify and equalize the electrical signal input by the photoelectric conversion unit 1, so as to facilitate the subsequent module units to perform corresponding processing.

[0063] When the input signal is a high-speed signal, this embodiment also involves the following design: Figure 5 As shown, the adaptive performance detection device that realizes transmission service imperceptibility also includes a clock data recovery unit 7, the input end of the clock data recovery unit 7 is connected to the output end of the amplification and equalization unit 5, and the output end of the clock data recovery unit 7 is connected to the input end of the path switching unit 21.

[0064] The clock data recovery unit 7 is used to perform clock data recovery processing on the high-speed signal. In order to be compatible with more service types and ensure compatibility with both high-speed and low-speed signals, this embodiment also provides another preferred design, such as Figure 6 As shown: the output end of the amplification and equalization unit 5 includes a fifth output end 51 and a sixth output end 52; the fifth output end 51 is connected to the input end of the clock data recovery unit 7, and the output end of the clock data recovery unit 7 is connected to the fifth input end 211 of the path switching unit 21; the sixth output end 52 is connected to the sixth input end 212 of the path switching unit 21.

[0065] In this embodiment, high-speed signals and low-speed signals are compatible at the same time, wherein the low-speed signal does not need to be processed by clock recovery, and therefore the path switching unit 21 and the amplification and equalization unit 5 are connected via two transmission paths. When the input signal is a high-speed signal, the high-speed signal is output from the fifth output terminal 51 and is processed by clock data recovery through the clock data recovery unit 7, and then is input from the fifth input terminal 211 to the path switching unit 21; when the input signal is a low-speed signal, the low-speed signal is output from the sixth output terminal 52 and is input from the sixth input terminal 212 to the path switching unit 21; through the above design, simultaneous compatibility with high-speed signals and low-speed signals is achieved.

[0066] In this embodiment, after converting the optical signal into an electrical signal, the photoelectric conversion unit 1 also converts the optical signal into a differential signal pair and transmits the differential signal pair to the amplification and equalization unit 5. Therefore, this embodiment also involves the following design:

[0067] like Figure 7 As shown, the receiving end of the amplifying and equalizing unit 5 includes a seventh receiving end 53 and an eighth receiving end 54; the seventh output end 11 of the photoelectric conversion unit 1 is connected to the seventh receiving end 53 of the amplifying and equalizing unit 5, and the eighth output end 12 of the photoelectric conversion unit 1 is connected to the eighth receiving end 54 of the amplifying and equalizing unit 5.

[0068] In this embodiment, a pair of differential signal lines can be set between the photoelectric conversion unit 1 and the amplification and equalization unit 5, wherein one end of one differential signal line is connected to the seventh output terminal 11, and the other end is connected to the seventh receiving terminal 53, and the differential signal line is used to transmit the first differential signal in the differential signal pair; one end of the other differential signal line is connected to the eighth output terminal 12, and the other end is connected to the eighth receiving terminal 54, and the differential signal line is used to transmit the second differential signal in the differential signal pair.

[0069] like Figure 7 As shown, the adaptive performance detection device that realizes transmission service without perception also includes a control unit 6, and the control unit 6 is connected to the photoelectric conversion unit 1, the loopback module 2, the electro-optical conversion unit 3 and the data analysis unit 4 respectively.

[0070] In this embodiment, the control unit 6 may be a host or a single chip microcomputer.

[0071] Embodiment 2:
