Description

High-speed electric connector

[ 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 high-speed electric connector.

[ background of the invention ]

The electrical connector assembly allows a user of the electronic device or external apparatus to transmit data to or communicate with other devices and apparatuses. Typically, the electrical connector assembly includes a pluggable module received within a receptacle assembly that includes a receptacle connector that is removably connectable to the pluggable module. The receptacle assembly includes a metal cage having an internal compartment that receives the pluggable module therein. A receptacle connector is retained in the interior compartment of the cage for connection with the pluggable module when the pluggable module is inserted therein.

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 IEEE 802.3z compliant 0 BaseXX, 0BaseLX/LH or 0BaseZX interfaces. Further, Cisco is offering a 0BaseLX/LH interface that fully complies with the IEEE 802.3z0BaseLX standard, but has a transmission distance on single mode fiber of up to 10 kilometers, 5 kilometers more than the common 0BaseLX 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. It is also desirable to increase port density and optimize the connection interface of the SFP module.

A new standard has been published and is referred to herein as the hot-plug (SFP) standard, which is an abbreviation for smallformplugble, 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). 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 basically the same as the GBIC.

Such interface connectors have higher and higher requirements on the anti-interference, grounding and shielding performances of the electrical connector assembly along with the improvement of the transmission rate, and an improved high-speed electrical connector is needed to realize better anti-interference and grounding effects, so as to realize higher-rate transmission.
