In this disclosure, many specific details are provided to provide a comprehensive understanding of the embodiments of the present disclosure; however, those skilled in the art will appreciate that the present disclosure can be practiced without one or more of these specific details; in other cases, well-known details are not shown or described to avoid obscuring the features of the present disclosure. The technical content and detailed description of the present disclosure are as follows, and are illustrated with the attached figures.

Please refer to FIG. 1, which is a block diagram of a switch device 102 of the present disclosure; please refer to FIG. 2, which is a block diagram of a linear drive pluggable optics (LPO) device 108 of the present disclosure; please refer to FIG. 3, which is a block diagram of a switch system 10 of the present disclosure.

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

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 converted impedance amplifier 120 ; the linear drive pluggable optical device 108 is plugged into the connection port 116 , so that the microprocessor 110 is electrically connected to the digital signal processor 104 through the connection port 116 .

When the LPOD 108 is plugged into the connection port 116 (for example, when the first LPOD 108 from left to right in FIG. 3 is plugged 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 may be, for example, but the present disclosure is not limited to including a manufacturer's name and a product model number.

Then, the digital signal processor 104 is configured to look up an optoelectronic parameter 114 corresponding to a port number 124 of the linear drive pluggable optical device 108 and the manufacturer name and the product model of the identification code 112 in the lookup table 106. The port number 124 represents the number of the port 116 into which the linear drive pluggable optical device 108 is plugged; the digital signal processor 104 must know which of the ports 116 the linear drive pluggable optical device 108 is plugged. The optoelectronic parameter 114 can be, for example, but the present disclosure is not limited to including an emission light power parameter, a laser operating voltage parameter, a laser operating current parameter, etc. The following table is a simple embodiment of the lookup table 106:

Port number Identification code Photoelectric parameters Manufacturer Name Product Model Transmitted light power parameters Laser operating voltage parameters Laser operating current parameters 01 First manufacturer First product model First parameter Second parameter The third parameter 02 First manufacturer Second product model Fourth parameter Fifth parameter Sixth parameter 03 Secondary manufacturer Third product model Seventh parameter Eighth parameter Ninth parameter

As described above, if the linear drive pluggable optical device 108 is inserted into the connection port 116 numbered 01 and the manufacturer name is a first manufacturer and the product model is a first product model, the digital signal processor 104 can look up the emission light power parameter, the laser operating voltage parameter and the laser operating current parameter of the connection port number 124 being 01, the manufacturer name being the first manufacturer and the product model being the first product model in the lookup table 106; that is, as shown in the above table, the emission light power parameter, the laser operating voltage parameter and the laser operating current parameter of the photoelectric parameter 114 will be looked up as a first parameter, a second parameter and a third parameter respectively.

In other words, the specific port 116 must be plugged into the linear drive pluggable optical device 108 having the specific identification code 112; for example, the port 116 numbered 01 must be plugged into the linear drive pluggable optical device 108 having the manufacturer name of the first manufacturer and the product model of the first product model; the reason is that the switch device 102 and the linear drive pluggable optical device 108 are connected to each other. The compatibility of the pluggable optical device 108 is critical to the linkage between the light emitted by the linear drive pluggable optical device 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, so the linear drive pluggable optical device 108 with any of the identification codes 112 may not work properly when plugged into the connection port 116 numbered 01. In other words, the identification code 112 is similar to a key that determines whether the connection port 116 is turned on.

In one specific embodiment of the present disclosure but not limiting the present disclosure, the lookup table 106 may be pre-filled and stored in the switch device 102, and if the digital signal processor 104 cannot find the corresponding port number 124, the manufacturer name and the product model in the lookup table 106, the switch device 102 issues a warning; for example, taking the above table as an example, if the port number 124 is 01 but the manufacturer name is a second manufacturer, the switch device 102 issues a warning; for another example, taking the above table as an example, if the port number 124 is 02 but the product model is a third product model, the switch device 102 issues a warning.

Next, the digital signal processor 104 is configured to transmit the photoelectric parameter 114 to the microprocessor 110 via the connection port 116; that is, the digital signal processor 104 is configured to inform the microprocessor 110 of the photoelectric parameter 114 via the connection port 116; in other words, the digital signal processor 104 is configured to write the photoelectric parameter 114 into the microprocessor 110 via the connection port 116.

Then, the microprocessor 110 is configured to store the photoelectric parameters 114, and the microprocessor 110 is configured to control the light source driver 118, the converted impedance amplifier 120 and other general components that are not shown in Figures 2 or 3 but belong to general linear drive pluggable optics with the photoelectric parameters 114 (that is, the microprocessor 110 is configured to use the photoelectric parameters 114 to control the light source driver 118, the converted impedance amplifier 120 and other general components that are not shown in Figures 2 or 3 but belong to general linear drive pluggable optics).

Finally, in order to verify that the LPOD 108 is properly driven, the LPOD 108 is configured to transmit a digital diagnostic monitoring The digital signal processor 104 is configured to transmit the 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 (i.e., 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 and transmit the adjusted optoelectronic parameter 114 to the microprocessor 110, and then the linear drive pluggable optical device 108 transmits the digital diagnostic monitoring data 122 to the digital signal processor 104 again.

The digital diagnostic monitoring data 122 may be, for example, but the present disclosure is not limited to, a temperature data, a transmitted optical power data, a received optical power data, a voltage data, a current data, etc. If the digital diagnostic monitoring data 122 is judged to be within the specification, the linear drive pluggable optical device 108 is judged to be driven correctly. If the digital signal processor 104 adjusts the photoelectric parameter 114 for more than 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 judged to be abnormal.

After the first linear drive pluggable optical device 108 from left to right in FIG. 3 completes the above operation process, each of the remaining linear drive pluggable optical devices 108 in FIG. 3 will also be configured to transmit the identification code 112 to the digital signal processor 104 to sequentially obtain the optoelectronic parameters 114, and the digital diagnostic monitoring data 122 will also be determined to be within the specification (i.e., repeating the above operation process).
