Abstract
An optical fiber transceiver with four electric interfaces belongs to optical fiber transceivers and solves the problems that an existing optical fiber transceiver provided with only one interface is insufficient in use and use of users can be affected when the interface is damaged and needs to be replaced. The optical fiber transceiver with the four electric interfaces comprises an optical fiber, a fiber converter module, a condenser coupling module, a switch, and an MCU ( micro control unit), wherein the fiber converter module is connected with the optical fiber, the condenser coupling module is connected with the fiber converter module, the switch is connected with the condenser coupling module, output ends of the switch are respectively connected with the four electric interfaces, and the MCU is connected with the fiber converter module and the switch respectively. The optical fiber transceiver with the four electric interfaces can be shared by a plurality of terminals simultaneously, solves the problem of shortage of electric interfaces of the existing optical fiber transceiver, and project cost is reduced. Furthermore, once one of the electric interfaces is damaged, other electric interfaces can be used normally, and accordingly, instant use of the users cannot be affected.
Description
Technical field
The utility model relates to a kind of fiber optical transceiver, refers in particular to a kind of fiber optical transceiver with four electricity mouths.
Background technology
Fiber optical transceiver is a kind of Ethernet transmission medium converting unit that the light signal of short-range twisted-pair feeder signal of telecommunication and long distance is exchanged, and also is referred to as optical-electrical converter (Fiber Converter) in a lot of places.Product generally is applied in Ethernet cable and can't covers, must use in the real network environment that optical fiber extends transmission distance, and the Access Layer that is positioned broadband metropolitan area network is usually used; In help last kilometer of optical fiber circuit is connected on metropolitan area network and the more outer field network simultaneously and has also brought into play enormous function.
Existing fiber optical transceiver structure is referring to Fig. 1, optical fiber 13 is sent into photoelectric conversion module 12 through the light signal of light mouth output, photoelectric conversion module 12 is subjected to MCU (single-chip microcomputer) 11 controls, output at photoelectric conversion module 12 is exported the signal of telecommunication by an electrical interface RJ45, fiber optical transceiver is two-way transmission signal, the signal of telecommunication that is user side converts light signal to by photoelectric conversion module 12, delivers to optical fiber 13.
As shown in Figure 1, existing fiber optical transceiver has only an electricity mouth, therefore can only be used for cell networks, in campus network and the enterprise network,, cause the electricity mouth not enough if the user who uses is too much, in addition owing to have only an electricity mouth, in case damage, need purchase again, change, not only waste fund but also waste the time of user's online.
The utility model content
The purpose of this utility model is in order to overcome the problem that prior art exists, and a fiber optical transceiver that has four electricity mouthful is provided, and solves after the not enough and electric mouth damage of single electricity port the more trouble of exchange device.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fiber optical transceiver with four electricity mouths is characterized in that comprising:
Optical fiber;
Photoelectric conversion module is connected with described optical fiber;
The capacitive coupling module is connected with described photoelectric conversion module;
Switch is connected with described capacitive coupling module, and the output of switch connects four electrical interfaces respectively;
MCU is connected with described photoelectric conversion module and switch respectively.
Described switch is the Switch of band RTL8306 chip.
Described electrical interface is RJ45.
The beneficial effects of the utility model:
Fiber optical transceiver with four electricity mouths of the present utility model, design by four electricity mouths, more user is used, buying, the replacing number of times of equipment such as switch have been reduced, if after the electricity mouthful damage, can use other electricity mouthful, thereby can not influence the time of user's online because of exchange device more.
For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is elaborated below with reference to accompanying drawing.
Description of drawings
Fig. 1 is existing fiber optical transceiver structural representation;
Fig. 2 is the fiber optical transceiver structural representation of four electricity mouths of the utility model band.
Embodiment
Accompanying drawing below in conjunction with embodiment is elaborated to embodiment of the present utility model.
Referring to Fig. 2, Fig. 2 is the fiber optical transceiver structural representation of four electricity mouths of the utility model band.
The utility model has added the Switch of the chip of a band RTL8306 on module on Fig. 1 prior art basis, detailed structure is as follows:
Optical fiber 23
Photoelectric conversion module 22 is connected with described optical fiber 23;
Capacitive coupling module 24 is connected with described photoelectric conversion module 22;
Switch (Switch) 25, be connected with described capacitive coupling module 24, the output of switch (Switch) 25 connects four electrical interface RJ45 respectively, exports four road signals of telecommunication by four electrical interface RJ45, and the switch 25 of present embodiment is the Switch of band RTL8306 chip;
MCU (single-chip microcomputer) 21 connects photoelectric conversion module 22 and switch (Switch) 25 respectively.
Fiber optical transceiver with four electricity mouths detects the realization principle:
Optical fiber 23 light signals are delivered to photoelectric conversion module 22 through the light mouth and are converted the signal of telecommunication to, by a switch 25, one tunnel electrical signal conversion is become four tunnel the signal of telecommunication, and this process is exactly one road light signal to be converted to four tunnel the signal of telecommunication, makes this fiber optical transceiver that four electricity mouths be arranged.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the purpose of this utility model, and be not with opposing qualification of the present utility model, as long as in essential scope of the present utility model, all will drop in the scope of claim of the present utility model variation, the modification of the above embodiment.
