Background technology
Fiber optical transceiver is generally applied in the real network environment that Ethernet cable cannot cover, must extend transmission distance with optical fiber, is helping that last kilometer of connection of optical fiber also brought into play to huge effect on metropolitan area network and more outer field network simultaneously.There is fiber optical transceiver, also for system need to be upgraded to optical fiber from copper cash, for being in want of funds, manpower or the user of time provide a kind of scheme of cheapness.The effect of fiber optical transceiver is that the signal of telecommunication that will send converts light signal to, and sends, and meanwhile, can convert the light signal receiving to the signal of telecommunication, the receiving terminal being input to.In the cable interface of fiber optical transceiver, comprise transmitting terminal and receiving terminal, therefore, the reception meeting that is sent in of signal produces interference mutually,, when holding wire and transmitting terminal, receiving terminal are set together, also can impact transmitting terminal and receiving terminal meanwhile.Thereby, mostly adopt blind hole impedance to reduce interference, but blind hole impedance is difficult to control, particularly when impedance mismatch, can increase loss of signal.
Utility model content
Based on this, be necessary to provide a kind of anti-interference and reduce the fiber optical transceiver cable interface module structure of loss of signal.
A kind of fiber optical transceiver cable interface module structure, for reducing the interference signal of fiber optical transceiver interface, comprises holding wire, circuit board for receiving and transmitter card; Also comprise barricade; Described circuit board for receiving and described transmitter card be arranged in parallel, described barricade is inserted between described circuit board for receiving and described transmitter card, described barricade is used for isolating described circuit board for receiving and described transmitter card, and described holding wire and described circuit board for receiving, described transmitter card and the isolation of described barricade arrange.
In an embodiment, described barricade is sheet metal therein.
In an embodiment, described barricade is welded on described circuit board for receiving therein.
In an embodiment, also comprise shielding ring therein, after described circuit board for receiving, described transmitter card and described barricade opposing parallel arrange, pass vertically described shielding ring simultaneously.
Therein in an embodiment, also comprise shell, described shell comprises drain pan and upper cover, described drain pan is provided with groove, for accommodating successively described transmitter card, described barricade, described circuit board for receiving and described shielding ring, described upper cover and described drain pan are fastened and connected, and make described transmitter card, described barricade, described circuit board for receiving and described shielding ring relatively fixing.
In an embodiment, also comprise snap close and drawstring therein, described snap close and described drawstring are located at described drain pan, and described snap close coordinates with described drawstring, for described shell and outer member are fixed.
Above-mentioned fiber optical transceiver cable interface module structure arranges shielding between circuit board for receiving and transmitter card, makes receiving and transmitting signal isolation, avoids phase mutual interference.
Holding wire is arranged to outside simultaneously, can have reduced the loss of holding wire cabling, and reduce blind hole, reduced the impedance discontinuity point on holding wire, reduce loss of signal.
Brief description of the drawings
Fig. 1 is fiber optical transceiver cable interface module structural representation.
Embodiment
A kind of fiber optical transceiver cable interface module structure, for reducing the interference signal of fiber optical transceiver interface, comprises holding wire, circuit board for receiving and transmitter card; Also comprise barricade; Circuit board for receiving and transmitter card be arranged in parallel, and barricade is inserted between circuit board for receiving and transmitter card, and barricade is used for isolating circuit board for receiving and transmitter card, and holding wire and circuit board for receiving, transmitter card and barricade isolation arrange.
Between circuit board for receiving and transmitter card, barricade is set, thereby can avoids signal to receive and the mutual interference of signal transmission phase, make to receive signal and transmitted signal isolation, shield respectively by circuit board for receiving and transmitter card.Thereby avoid in signals transmission occurring because of circuit board for receiving and the interference signal of transmitter card phase mutual interference generation.Meanwhile, holding wire is arranged to outside, because same impedance is walked outer field holding wire than the signal live width of internal layer, thereby can reduces the loss of holding wire cabling, and reduce blind hole, reduce the impedance discontinuity point on holding wire, reduce loss of signal.
As shown in Figure 1, be fiber optical transceiver cable interface module structural representation.
A kind of fiber optical transceiver cable interface module structure, for reducing the interference signal of fiber optical transceiver interface, comprises holding wire (not shown), circuit board for receiving 101 and transmitter card 102; , also comprise barricade 103; Circuit board for receiving 101 be arranged in parallel with transmitter card 102, barricade 203 is inserted between circuit board for receiving 101 and transmitter card 102, barricade 103 is for isolating circuit board for receiving 101 and transmitter card 102, and holding wire (not shown) and circuit board for receiving 101, transmitter card 102 and barricade 103 isolation arrange.
Barricade 103 is sheet metal.
Barricade 103 is welded on circuit board for receiving 101.
When mounted, first, by circuit board for receiving 101 and transmitter card 102 and cable welding, complete after welding, before mounting casing, barricade 103 is installed, owing to being provided with pad on circuit board, therefore, generally barricade 103 is fixed on circuit board for receiving 101 or on transmitter card 102.
Fiber optical transceiver cable interface module structure also comprises shielding ring 104, passes vertically shielding ring 104 after circuit board for receiving 101, transmitter card 102 and barricade 103 opposing parallel arrange simultaneously.
