[ technical field ] A method for producing a semiconductor device
The embodiment of the application relates to the field of communication transmission, in particular to a shielding cage assembly and an electric connector assembly.
[ background of the invention ]
A gigabit interface connector (GBIC) is a hot-pluggable input/output device that plugs into a gigabit ethernet port/slot responsible for connecting the port to a fiber optic network. GBIC can be used and interchanged on various Cisco products, and can be mixed port by port with 1000BaseSX, 1000BaseLX/LH or 1000BaseZX interfaces that conform to IEEE 802.3 z. Further, Cisco is offering a 1000BaseLX/LH interface that fully complies with the IEEE 802.3z1000BaseLX standard, but has a transmission distance on single mode fiber of up to 10 kilometers, 5 kilometers more than the normal 1000BaseLX interface. In summary, as new functions are continuously developed, it will be easier to upgrade these modules to the latest interface technologies, thereby maximizing customer investment.
These conventional plug-in designs have been successful in the past, but they tend not to meet the goals of continued miniaturization in the industry. It is desirable to miniaturize transceivers to increase port density associated with network connections such as switchboxes, cable patch panels, wiring closets, and computer input/output (I/O). Conventional pluggable module configurations are unable to meet these parameter requirements.
A new standard has been published and is referred to herein as the hot-plug (SFP) standard, which is an abbreviation for Small Form-factor plug, and may be simply understood as an upgraded version of GBIC. The SFP module has a half of volume reduction compared with the GBIC module, and the number of ports which is more than one time can be configured on the same panel. The other functions of the SFP module are substantially identical to the GBIC. Some switch vendors call SFP modules as miniaturized GBIC (MINI-GBIC).
At present, the QSFP-DD (Small Form-factor plug-able Double sensitivity) is developed, and the QSFP-DD specification is published, which defines a high-speed communication module with eight channels. The running speed of each channel is 25Gbit/s or 50Gbit/s, so that the QSFP-DD module supports 200Gbit/s or 400Gbit/s Ethernet application. At the same time of speed improvement, the speed is more suitable for miniaturization design. After the SFP and QSFP are fixed to the circuit board, the matching with the circuit board and the space utilization rate are also important in design, so that the utilization rate of the internal space of the electronic device can be integrally improved, the integration level is improved, and in addition, along with the continuous improvement of the transmission rate, the heat dissipation design requirement of the product is higher and higher, and the traditional design can not meet the performance requirement which is improved day by day at present.
Accordingly, there is a need for an improved interface connector of the type known in the art that overcomes the deficiencies of the prior art.
