Description
Technical field
The present invention relates to a kind of hot swap type interface connectors, more particularly to one kind easy ting produce heat in use
Hot swap type interface connector.
Background technology
Gigabit interface connector (GBIC) is a kind of input-output apparatus of hot plug, which is inserted into kilomegabit
In ethernet port/slot, it is responsible for linking together port and fiber optic network.GBIC can make on various cisco products
With and exchange, and can port basis with 1000BaseSX, 1000BaseLX/LH or 1000BaseZX for following IEEE802.3z
Interface is mixed.Furtherly, Cisco is providing a kind of IEEE802.3z1000BaseLX standards of fully complying with
1000BaseLX/LH interfaces, but its transmission range on single mode optical fiber is up to 10 kilometers, is connect than common 1000BaseLX
Mouth is 5 kilometers remote.In short, continually developing with new function, these module upgrades will be more prone to newest interfacing, from
And clients investment is enable to play greatest benefit.
The plug-in type design that these were traditional in the past has succeeded, but they tend to reach industrial lasting
Miniaturization target.It is expected that making transceiver miniaturization to increase and such as distribution box, cable connection panel, wiring closet
With the associated port density of network connection of computer input/output (I/O).Traditional insertable module structure can not
Meet these parameter needs.It is also desirable that increasing port density and the connecting interface of SFP modules being made to optimize.
New standard is had issued at present, and referred to herein as hot swap type (SFP) standard, SFP are
The abbreviation of SMALLFORMPLUGGABLE can simply be interpreted as the upgraded version of GBIC.SFP module volume ratio GBIC modules
Half is reduced, can be configured on identical panel and have more one times or more of port number.Other functions of SFP modules substantially and
GBIC is consistent.Some interchanger manufacturer SFP modules are referred to as miniaturization GBIC (MINI-GBIC).SFP module volume ratio GBIC modules
Half is reduced, can be configured on identical panel and have more one times or more of port number.Other functions of SFP modules substantially and
GBIC is identical.
In the prior art, when the hot swap type interface connector accommodates grafting optical module, it will produce a large amount of heat
Amount does not have shrapnel and heat conductive pad inside common cage body, when being inserted into optical module, heat can by air transmitted to cage body, then
By cage body by external equipment, such as fan, thermally conductive sheet etc. radiates outward.But since air drag is big, heat dissipation capacity is usually waited a moment less,
Temperature inside cage body can be stepped up with the extension of time, when cage body temperature reaches a certain level, will produce dead
Machine, disabler influence to use.
Therefore, it is necessary to be improved to existing hot swap type interface connector in the prior art described scarce to overcome
It falls into.
