图1所示的介质转换系统1并非没有缺点。具体而言,介质转换器14必须同时具有RJ-45接口140与SFP+接口142,且光纤线缆18也必须使用两个插拔式收发模块182来连接SFP+接口网络交换器12与介质转换器14;如此一来,当大范围地布建网络通讯链路时,势必会增加链路的复杂度与困难度,同时也会提高链路的布建成本。另一方面,信号经由插拔式收发模块与SFP+接口链接传递,势必会造成信号的衰减与噪声的增加;因此,过度的接口链接,将会严重影响信号传递的质量。The medium conversion system 1 shown in Fig. 1 is not without drawbacks. In particular, the media converter 14 must have both the RJ-45 interface 140 and the SFP+ interface 142, and the fiber optic cable 18 must also use the two plug-in transceiver modules 182 to connect the SFP+ interface network switch 12 to the media converter 14. As a result, when a network communication link is deployed on a large scale, the complexity and difficulty of the link are bound to increase, and the link construction cost is also increased. On the other hand, the signal is transmitted via the plug-in transceiver module and the SFP+ interface link, which will inevitably cause signal attenuation and noise increase; therefore, excessive interface links will seriously affect the quality of signal transmission.
综上所述,如何在RJ-45接口与插拔式收发模块接口之间提供一种理想的转换方式,以降低链路布建成本与复杂度,同时提供良好的信号传递质量,实为所述领域的技术者亟需解的课题。In summary, how to provide an ideal conversion method between the RJ-45 interface and the plug-in transceiver module interface to reduce the cost and complexity of link deployment, while providing good signal transmission quality, The subject of the field is urgently needed to solve the problem.

本发明的最佳实施方式BEST MODE FOR CARRYING OUT THE INVENTION
本发明的第一实施例为一介质转换系统2,其示意图描绘于图2。介质转换系统2包括一RJ-45接口网络交换器(Network Switch)20、一插拔式收发模块接口网络交换器22、一RJ-45线缆26以及一直连式介质转换器,所述直连式介质转换器包括一介质转换模块24、一连接线28以及一插拔式收发模块282。其中,介质转换模块24具有一外壳248,且外壳248具有一RJ-45接口240,可插式地连接至RJ-45线缆26以接收RJ-45接口信号,连接线28直接连接于介质转换模块24,插拔式收发模块282电性连接于连接线28。介质转换模块24还包括一转换电路,电性连接于RJ-45接口240及连接线28间,用以作为RJ-45接口信号与插拔式收发模块接口信号间的接口信号转换。A first embodiment of the present invention is a media conversion system 2, a schematic view of which is depicted in FIG.

Hereinafter, the operation mode of the medium conversion system 2 of the present invention will be described in detail.
介质转换系统2用以将一RJ-45接口信号转换为一插拔式收发模块接口信号。具体而言,RJ-45接口网络交换器20用以处理RJ-45接口信号,并可通过其RJ-45接口200输出RJ-45接口信号,RJ-45线缆26连接RJ-45接口网络交换器20的RJ-45接口200与介质转换模块24的RJ-45接口240,用以传递RJ-45接口信号至介质转换模块24;接着,介质转换模块24用以将RJ-45接口信号转换为插拔式收发模块接口信号,并将插拔式收发模块接口信号传送至连接线28,连接线28用以传递插拔式收发模块接口信号至插拔式收发模块282;最后,插拔式收发模块282连接于插拔式收发模块接口网络交换器22的插拔式收发模块接口222,并将插拔式收发模块接口信号传送至插拔式收发模块接口网络交换器22,插拔式收发模块接口网络交换器22则用以处理插拔式收发模块接口信号。The medium conversion system 2 is configured to convert an RJ-45 interface signal into a plug-in transceiver module interface signal. Specifically, the RJ-45 interface network switch 20 is configured to process RJ-45 interface signals, and can output RJ-45 interface signals through its RJ-45 interface 200, and the RJ-45 cable 26 is connected to the RJ-45 interface network switch. The RJ-45 interface 200 of the device 20 and the RJ-45 interface 240 of the medium conversion module 24 are configured to transmit the RJ-45 interface signal to the medium conversion module 24; then, the medium conversion module 24 is configured to convert the RJ-45 interface signal into The plug-in transceiver module interface signal transmits the plug-in transceiver module interface signal to the connection line 28, and the connection line 28 transmits the plug-in transceiver module interface signal to the plug-in transceiver module 282; finally, the plug-in transceiver The module 282 is connected to the plug-in transceiver module interface 222 of the plug-in transceiver module interface network switch 22, and transmits the plug-in transceiver module interface signal to the plug-in transceiver module interface network switch 22, and the plug-in transceiver module The interface network switch 22 is configured to process the pluggable transceiver module interface signals.
同理,介质转换系统2亦可用以将一插拔式收发模块接口信号转换为一RJ-45接口信号。具体而言,插拔式收发模块接口网络交换器22通过其插拔式收发模块接口222输出插拔式收发模块接口信号至插拔式收发模块282,连接线28与插拔式收发模块282电性连接,用以将插拔式收发模块接口信号传递至介质转换模块24;接着,介质转换模块24用以将插拔式收发模块接口信号转换为RJ-45接口信号,并将RJ-45接口信号通过其RJ-45接口200传送至RJ-45线缆26,RJ-45线缆26用以传递RJ-45接口信号至RJ-45接口网络交换器20,RJ-45接口网络交换器20通过其RJ-45接口200接收RJ-45接口信号,并处理RJ-45接口信号。Similarly, the medium conversion system 2 can also be used to convert a plug-in transceiver module interface signal into an RJ-45 interface signal. Specifically, the plug-in transceiver module interface network switch 22 outputs the plug-in transceiver module interface signal to the plug-in transceiver module 282 through the plug-in transceiver module interface 222, and the connection line 28 and the plug-in transceiver module 282 The connection is used to transmit the plug-in transceiver module interface signal to the media conversion module 24; then, the media conversion module 24 is configured to convert the plug-in transceiver module interface signal into an RJ-45 interface signal, and the RJ-45 interface The signal is transmitted through its RJ-45 interface 200 to the RJ-45 cable 26, which is used to pass the RJ-45 interface signal to the RJ-45 interface network switch 20, and the RJ-45 interface network switch 20 passes Its RJ-45 interface 200 receives the RJ-45 interface signal and processes the RJ-45 interface signal.
须特别说明者,本发明的直连式介质转换器仅使用一个插拔式收发模块。具体而言,连接线28直接电性连接至介质转换模块24,介质转换模块24将RJ-45接口信号转换为插拔式收发模块接口信号后,直接传送至连接线28,而非通过插拔式收发模块接口与插拔式收发模块来连接连接线28,亦即介质转换模块24并不具有插拔式收发模块接口,且连接线28仅连接一个插拔式收发模块282。据此,本发明的直连式介质转换器可减少插拔式收发模块的使用数量,进而降低链路布建成本与复杂度;另一方面,本发明的直连式介质转换器亦可减少插拔式收发模块与插拔式收发模块接口的链接次数,进而减少信号衰减与失真,提升信号传递质量。It should be particularly noted that the direct-connected media converter of the present invention uses only one plug-in transceiver module. Specifically, the connection line 28 is directly electrically connected to the medium conversion module 24, and the medium conversion module 24 converts the RJ-45 interface signal into a plug-in transceiver module interface signal, and then directly transmits it to the connection line 28 instead of plugging and unplugging The transceiver module interface and the plug-in transceiver module are connected to the connection cable 28, that is, the media conversion module 24 does not have a plug-in transceiver module interface, and the connection cable 28 is connected to only one plug-in transceiver module 282. Accordingly, the direct-connected media converter of the present invention can reduce the number of plug-in transceiver modules used, thereby reducing the cost and complexity of link deployment; on the other hand, the direct-connected media converter of the present invention can also be reduced. The number of links between the plug-in transceiver module and the plug-in transceiver module interface reduces signal attenuation and distortion and improves signal transmission quality.

The direct-connected media converter 3 includes a media conversion module 24, a connection line 28, and a plug-in transceiver module 282.

In detail, the RJ-45 interface 240 is configured to receive the RJ-45 interface signal and transmit the RJ-45 interface signal to the converter 242. The converter 242 is electrically connected to the RJ-45 interface 240 and the physical layer integrated circuit 244. To transmit the RJ-45 interface signal and provide isolation between the RJ-45 interface 240 and the physical layer integrated circuit 244. Specifically, the converter 242 can mainly implement three functions. Firstly, the DC isolation effect is provided. The Netcom devices separated by two places may not have the same ground potential, and if connected directly, the Netcom device may be damaged, or It is caused by deterioration of signal transmission quality. The converter can be used to isolate DC current to avoid affecting Netcom equipment or signal quality. Secondly, it provides noise isolation effect.
