DETAILED DESCRIPTION

[0022] In the present disclosure, numerous specific details are provided, to provide a comprehensive understanding of embodiments of the present disclosure. However, those skilled in the art may understand that the present disclosure may be practiced without one or more of these specific details. In other instances, well-known details are not shown or described to avoid obscuring features of the present disclosure. The technical content and the detailed description of the present disclosure are as follows with reference to the figures.

[0023] FIG. 1 shows a block diagram of a switch apparatus 102 of the present disclosure. FIG. 2 shows a block diagram of a linear drive pluggable optics (commonly referred to as LPO) apparatus 108 of the present disclosure. FIG. 3 shows a block diagram of a switch system 10 of the present disclosure. Please refer to FIG. 1, FIG. 2, and FIG. 3 at the same time.

[0024] As shown in FIG. 3, the switch system 10 of the present disclosure includes a switch apparatus 102 and a plurality of linear drive pluggable optics apparatuses 108. The switch apparatus 102 includes a digital signal processor 104, a lookup table 106, and a plurality of connection ports 116. Each of the linear drive pluggable optics apparatuses 108 includes a microprocessor 110, a light source driver 118, and a transimpedance amplifier (commonly referred to as TIA) 120.

[0025] The connection ports 116 are electrically connected to the digital signal processor 104. The microprocessor 110 is electrically connected to the light source driver 118 and the transimpedance amplifier 120. The linear drive pluggable optics apparatus 108 plugs into the connection port 116, so that the microprocessor 110 is electrically connected to the digital signal processor 104 through the connection port 116.

[0026] When the linear drive pluggable optics apparatus 108 plugs into the connection port 116 (for example, when the first linear drive pluggable optics apparatus 108 from left to right in FIG. 3 plugs into the first connection port 116 from left to right in FIG. 3), the microprocessor 110 is configured to transmit an identification code 112 to the digital signal processor 104 through the connection port 116, wherein the identification code 112 includes, for examples but not limited to, a manufacturer name and a product model.

[0027] Then, the digital signal processor 104 is configured to search the lookup table 106 for an optoelectronic parameter 114 corresponding to a connection port number 124 of the linear drive pluggable optics apparatus 108 and the manufacturer name and the product model of the identification code 112. The connection port number 124 represents the number of the connection port 116 where the linear drive pluggable optics apparatus 108 plugs. The digital signal processor 104 must know which of the connection ports 116 the linear drive pluggable optics apparatus 108 plugs into. The optoelectronic parameter 114 includes, for examples but not limited to, a transmitting optical power parameter, a laser operating voltage parameter, a laser operating current parameter, and so on. The following table is a simple embodiment of the lookup table 106.

TABLE-US-00001 optoelectronic parameter transmitting laser laser connection identification code optical operating operating port manufacturer product power voltage current number name model parameter parameter parameter 01 first first first second third manufacturer product parameter parameter parameter model 02 first second fourth fifth sixth manufacturer product parameter parameter parameter model 03 second third seventh eighth ninth manufacturer product parameter parameter parameter model

[0028] Following the above, if the linear drive pluggable optics apparatus 108 plugs into the connection port 116 numbered 01, and if the manufacturer name is a first manufacturer, and if the product model is a first product model, then the digital signal processor 104 searches in the lookup table 106 for the transmitting optical power parameter, the laser operating voltage parameter, and the laser operating current parameter corresponding to the connection port number 124 numbered 01, the manufacturer name which is the first manufacturer, and the product model which is the first product model. Namely, as shown in the above table, the transmitting optical power parameter, the laser operating voltage parameter, and the laser operating current parameter of the optoelectronic parameter 114 are searched as a first parameter, a second parameter, and a third parameter.

[0029] In other words, the specific connection port 116 has to be plugged into the linear drive pluggable optics apparatus 108 having the specific identification code 112. For example, the connection port 116 numbered 01 mentioned above has to be plugged into the linear drive pluggable optics apparatus 108 having the manufacturer name as the first manufacturer and the product model as the first product model. The reason is the compatibility of the switch apparatus 102 with the linear drive pluggable optics apparatus 108; the key lies in the linkage between the emitted light of the linear drive pluggable optics apparatus 108 and the digital signal processor 104; the parameter settings of the first manufacturer and the parameter settings of the second manufacturer may be different, and therefore the linear drive pluggable optics apparatus 108 having any identification code 112 plugging into the connection port 116 numbered 01 may not work properly. Namely, the identification code 112 is similar to a key and may determine whether the connection port 116 is conducted.

[0030] In one embodiment of the present disclosure (but the embodiment is not limiting the present disclosure), the lookup table 106 may be pre-filled and stored in the switch apparatus 102, and if the digital signal processor 104 cannot find the corresponding connection port number 124, the corresponding manufacturer name, or the corresponding product model, then the switch apparatus 102 provides a warning. For example, taking the above table as an example, if the connection port number 124 is 01 but the manufacturer name is a second manufacturer, then the switch apparatus 102 provides the warning. For another example, taking the above table as an example, if the connection port number 124 is 02 but the product model is a third product model, then the switch apparatus 102 provides the warning.

[0031] Then, the digital signal processor 104 is configured to transmit the optoelectronic parameter 114 to the microprocessor 110 through the connection port 116. Namely, the digital signal processor 104 is configured to inform the microprocessor 110 of the optoelectronic parameter 114 through the connection port 116. In other words, the digital signal processor 104 is configured to write the optoelectronic parameter 114 into the microprocessor 110 through the connection port 116.

[0032] Then, the microprocessor 110 is configured to store the optoelectronic parameter 114, and the microprocessor 110 is configured to control the light source driver 118, the transimpedance amplifier 120, and other conventional components (which are not shown in FIG. 2 or FIG. 3, and which belong to the conventional linear drive pluggable optics) with the optoelectronic parameter 114. Namely, the microprocessor 110 is configured to use the optoelectronic parameter 114 to control the light source driver 118, the transimpedance amplifier 120, and other conventional components (which are not shown in FIG. 2 or FIG. 3, and which belong to the conventional linear drive pluggable optics).

[0033] Finally, in order to verify whether the linear drive pluggable optics apparatus 108 is driven correctly, the linear drive pluggable optics apparatus 108 is configured to transmit a digital diagnostic monitoring (commonly referred to as DDM) data 122 to the digital signal processor 104. The digital signal processor 104 is configured to determine whether the digital diagnostic monitoring data 122 is within a specification. In response to the digital diagnostic monitoring data 122 not being within the specification (namely, if the digital diagnostic monitoring data 122 is not within the specification), the digital signal processor 104 is configured to adjust the optoelectronic parameter 114 to obtain an adjusted optoelectronic parameter and transmit the adjusted optoelectronic parameter to the microprocessor 110 (namely, the digital signal processor 104 is configured to adjust the optoelectronic parameter 114 and transmit the optoelectronic parameter 114 (which is adjusted) to the microprocessor 110), and then the linear drive pluggable optics apparatus 108 transmits the digital diagnostic monitoring data 122 to the digital signal processor 104 again.

[0034] The digital diagnostic monitoring data 122 includes, for examples but not limited to, a temperature data, a transmitting optical power data, a receiving optical power data, a voltage data, a current data, and so on. If the digital diagnostic monitoring data 122 is determined to be within the specification, the linear drive pluggable optics apparatus 108 is determined to be driven correctly. If the number of times that the digital signal processor 104 adjusts the optoelectronic parameter 114 exceeds a predetermined number of times but the digital diagnostic monitoring data 122 is still not within the specification, the digital diagnostic monitoring data 122 is determined to be abnormal.

[0035] After the first linear drive pluggable optics apparatus 108 from left to right in FIG. 3 completes the above operation process, each of the remaining linear drive pluggable optics apparatuses 108 in FIG. 3 is also be configured to transmit the identification code 112 to the digital signal processor 104 to sequentially obtain the optoelectronic parameter 114, and the digital diagnostic monitoring data 122 is also be determined whether the digital diagnostic monitoring data 122 is within the specification (namely, the above operation process is repeated).

[0036] Please refer to FIG. 3 again. The switch apparatus 102 of the present disclosure is applied to a plurality of linear drive pluggable optics apparatuses 108. The switch apparatus 102 includes a lookup table 106, a digital signal processor 104, and a plurality of connection ports 116. Each of the linear drive pluggable optics apparatuses 108 includes a microprocessor 110, a light source driver 118, and a transimpedance amplifier 120.

[0037] The connection ports 116 are electrically connected to the digital signal processor 104. The linear drive pluggable optics apparatus 108 plugs into the connection port 116, so that the digital signal processor 104 is electrically connected to the microprocessor 110 through the connection port 116.

[0038] The microprocessor 110 transmits an identification code 112 to the switch apparatus 102; namely, the digital signal processor 104 receives the identification code 112 transmitted by the microprocessor 110 through the connection port 116. The digital signal processor 104 is configured to search in the lookup table 106 for an optoelectronic parameter 114 corresponding to a connection port number 124 of the linear drive pluggable optics apparatus 108 and the identification code 112. The digital signal processor 104 is configured to transmit the optoelectronic parameter 114 to the microprocessor 110 through the connection port 116.

[0039] The linear drive pluggable optics apparatus 108 transmits a digital diagnostic monitoring data 122 to the digital signal processor 104. The digital signal processor 104 is configured to determine whether the digital diagnostic monitoring data 122 is within a specification. In response to the digital diagnostic monitoring data 122 not being within the specification, the digital signal processor 104 is configured to adjust the optoelectronic parameter 114 to obtain an adjusted optoelectronic parameter and transmit the adjusted optoelectronic parameter to the microprocessor 110. The digital diagnostic monitoring data 122 includes a temperature data, a transmitting optical power data, a receiving optical power data, a voltage data, and a current data. The optoelectronic parameter 114 includes a transmitting optical power parameter, a laser operating voltage parameter, and a laser operating current parameter.

[0040] The remaining technical contents of the switch apparatus 102 of the present disclosure are the same as the technical contents of the switch system 10 of the present disclosure mentioned above, and therefore are not described again.

[0041] Please refer to FIG. 3 again. The linear drive pluggable optics apparatus 108 of the present disclosure is applied to a switch apparatus 102. The linear drive pluggable optics apparatus 108 includes a microprocessor 110, a light source driver 118, and a transimpedance amplifier 120. The switch apparatus 102 includes a digital signal processor 104 and a lookup table 106.

[0042] The microprocessor 110 is electrically connected to the light source driver 118 and the transimpedance amplifier 120. The linear drive pluggable optics apparatus 108 plugs into the switch apparatus 102, so that the microprocessor 110 is electrically connected to the digital signal processor 104.

[0043] The microprocessor 110 is configured to transmit an identification code 112 to the digital signal processor 104. The digital signal processor 104 searches the lookup table 106 for an optoelectronic parameter 114 corresponding to a connection port number 124 of the linear drive pluggable optics apparatus 108 and the identification code 112. The digital signal processor 104 transmits the optoelectronic parameter 114 to the microprocessor 110. The microprocessor 110 is configured to store the optoelectronic parameter 114. The microprocessor 110 is configured to control the light source driver 118 and the transimpedance amplifier 120 with the optoelectronic parameter 114. The optoelectronic parameter 114 includes a transmitting optical power parameter, a laser operating voltage parameter, and a laser operating current parameter.

[0044] The remaining technical contents of the linear drive pluggable optics apparatus 108 of the present disclosure are the same as the technical contents of the switch system 10 of the present disclosure mentioned above, and therefore are not described again.

[0045] In the present disclosure, it should be noted that the switch apparatus 102 and the linear drive pluggable optics apparatus 108 of the present disclosure mentioned above must include other conventional components (which are not shown in FIG. 1, FIG. 2, or FIG. 3, and which belong to the conventional switch and the conventional linear drive pluggable optics), to maintain the conventional operations of the switch apparatus 102 and the linear drive pluggable optics apparatus 108. In order to avoid obscuring the features of the present disclosure, the conventional components are not described here.

[0046] The switch apparatus 102 may also include a plurality of the digital signal processors 104 (for example, four digital signal processors 104) to correspond to the linear drive pluggable optics apparatuses 108. For example, if the switch system 10 includes thirty-two linear drive pluggable optics apparatuses 108, then one digital signal processor 104 corresponds to eight linear drive pluggable optics apparatuses 108.

[0047] The advantage of the present disclosure is to reduce the power consumption of the switch system 10. The linear drive pluggable optics apparatuses 108 of the present disclosure may share the digital signal processor 104 through the lookup table 106 to work, so that the power consumption of the switch system 10 of the present disclosure may be greatly reduced. In addition to being applied to the linear drive pluggable, the present disclosure may also be applied to the co-packaged optics (commonly referred to as CPO).

[0048] Although the present disclosure has been described with reference to the embodiment thereof, it will be understood that the present disclosure is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the present disclosure.
