Description
Technical Field
The invention belongs to the technical field of photoelectric interface connectors, and particularly relates to a hot plug type interface connector.
Background
Gigabit interface connectors (GBICs) are hot-plugged input/output devices that plug into gigabit ethernet ports/slots, responsible for connecting the ports to the fiber optic network. GBIC can be used and interchanged on a variety of Cisco products and can be mixed with 1000BaseSX, 1000BaseLX/LH or 1000BaseZX interfaces compliant with IEEE 802.3z on a port-by-port basis. Furthermore, cisco is providing a 1000BaseLX/LH interface that is fully compliant with the IEEE 802.3z1000BaseLX standard, but that is traveling up to 10 kilometers over single mode fiber, 5 kilometers farther than the normal 1000BaseLX interface. In summary, with the continued development of new functions, it will be easier to upgrade these modules to the latest interface technology, thereby enabling the customer investment to take maximum advantage.
These traditional plug-in designs have been successful in the past, but they tend not to achieve the industry's continuing goal of miniaturization. It is desirable to miniaturize transceivers to increase the port density associated with network connections such as distribution boxes, cable patch panels, wiring closet, and computer input/output (I/O). Conventional pluggable module configurations are not able to meet these parameter requirements. It is also desirable to increase port density and optimize the connection interfaces of the SFP modules.
A new standard has been published and is referred to herein as the hot plug (SFP) standard, which is an abbreviation for smalllform and can be simply understood as an upgraded version of GBIC. The SFP module volume is reduced by half compared with the GBIC module, and more than one time of port number can be configured on the same panel. Other functions of the SFP module are substantially identical to GBIC. Some switch manufacturers call SFP modules miniaturized GBICs (MINI-GBICs). The SFP module volume is reduced by half compared with the GBIC module, and more than one time of port number can be configured on the same panel. The other functions of the SFP module are essentially the same as GBIC.
The standard specifies that in addition to miniaturizing the module, it is desirable to increase the operating frequency. For example, practical applications may move rapidly from a range below gigabits to well over one gigabit.
Minimizing the module while maintaining or even increasing its operating speed poses a number of design problems, particularly in applications where data transfer rates are high, for example, in the range of 1-10Gbs (gigabits/second).
EMC (Electro Magnetic Compatibility), also known as electromagnetic compatibility, refers to the ability of a device or system to operate satisfactorily in its electromagnetic environment without intolerable electromagnetic interference to any device in its environment. EMC includes two requirements: on one hand, electromagnetic interference generated by equipment on the environment in the normal operation process cannot exceed a certain limit value; on the other hand, the device has a certain degree of immunity, namely electromagnetic sensitivity, to electromagnetic interference existing in the environment.
However, in the prior art, SFP receptacle connectors include a housing and at least one plug device disposed in the housing; the connector is easy to radiate outwards through a module buckle reed gap, and thus, the shell cannot realize a complete shielding effect on the connector.
Accordingly, there is a need for improvements in the art that overcome the above-described deficiencies.
