Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication transmission, and particularly to a high-speed electrical connector.

Background Art

[0002] An electrical connector assembly allows a user of an electronic device or an external device to transfer data to or communicate with other devices and apparatuses. Generally, an electrical connector assembly includes a pluggable module received within a receptacle assembly, and the receptacle assembly includes a receptacle connector removably coupled to the pluggable module. The receptacle assembly includes a metal cage having an internal compartment in which the pluggable module is received. The receptacle connector is held within the internal compartment of the cage for connection to the pluggable module when the pluggable module is inserted therein.

[0003] A Gigabit Interface Converter (GBIC) is a hot-pluggable input / output device that is inserted into a Gigabit Ethernet port / slot and is responsible for connecting the port to a fiber optic network. GBICs can be used and interchanged on various Cisco products and can be mixed with 0BaseSX, 0BaseLX / LH, or 0BaseZX interfaces compliant with IEEE 802.3z on a per-port basis. Further, Cisco is offering a 0BaseLX / LH interface that fully complies with the IEEE 802.3z 0BaseLX standard, but its transmission distance on single-mode fiber is up to 10 kilometers, which is 5 kilometers farther than that of a common 0BaseLX interface. In summary, with the continuous development of new functions, it will be easier to upgrade these modules to the latest interface technologies, thus maximizing the benefits of customer investments.

[0004] In the past, these traditional plug-in designs have been successful, but they tend not to achieve the goal of continuous miniaturization in the industry. It is desired to miniaturize transceivers to increase the port density associated with network connections such as distribution boxes, cable patch panels, wiring closets, and computer input / output (I / O). Traditional pluggable module configurations cannot meet these parameter requirements. It is also desired to increase the port density and optimize the connection interfaces of SFP modules.

[0005] A new standard has been announced and is hereby referred to as the hot-pluggable (SFP) standard. SFP is an abbreviation for SMALL FORM PLUGGABLE and can be simply understood as an upgraded version of GBIC. The volume of the SFP module is reduced by half compared to the GBIC module, and more than twice the number of ports can be configured on the same panel. The other functions of the SFP module are basically the same as those of GBIC. Some switch manufacturers refer to the SFP module as a miniaturized GBIC (MINI-GBIC). The volume of the SFP module is reduced by half compared to the GBIC module, and more than twice the number of ports can be configured on the same panel. The other functions of the SFP module are basically the same as those of GBIC.

[0006] For such interface connectors, with the increase in transmission rate, the requirements for the anti-interference, grounding, and shielding performance of the electrical connector components are also getting higher and higher. It is necessary to provide an improved high-speed electrical connector to achieve better anti-interference and grounding effects, and thus achieve higher-rate transmission.
