Detailed description of the invention
As shown in Figure 2, be the first embodiment of single fiber bi-directional optical fiber transceiver of the present invention, for the signal transmitting and receiving of single fiber, comprise three-way body 10, optical transmitting set 20, fibre-optical splice assembly 30, optical receiver 40 and optical filter assembly 50 etc.
The left and right two-port of this three-way body 10 is installed respectively optical transmitting set 20 and fibre-optical splice assembly 30, and three-way body 10 top port are installed optical receiver 40, and optical filter assembly 50 is arranged between optical transmitting set 20, fibre-optical splice assembly 30, optical receiver 40, change the path of light, realize the transmitting-receiving of signal. Understandable, this three-way body 10, optical transmitting set 20, optical receiver 40 and optical filter assembly 50 etc., can the existing various three-way bodies 10 of choice for use, optical transmitting set 20, optical receiver 40 and optical filter assembly 50.
Described in this, fibre-optical splice assembly 30 is made up of fixed muffle 51 and the porcelain bushing 52 that is arranged in fixed muffle 51, save the ceramic insertion core of commonly using, and improve new mechanism size and must not use ceramic insertion core and only need use a fixed muffle 51 can reach the function that single fiber bi-directional transmits to shorten fibre-optical splice assembly 30 to the distance of optical transmitting set 20 with optical receiver 40 common focal positions, to reach.
This fixed muffle 51 can be selected metal fixed muffle, comprises the base plate that hollow tube-shape main body and the one end in cylindrical body arrange. In the middle of this porcelain bushing 52, be provided with the access space of directly inserting, arrive plate inner wall face for the fibre core 61 of optical fiber 60. This base plate is provided with the loophole relative with the fibre core 61 of optical fiber 60 311, and loophole 311 imports optical fiber 60 fibre core 61 as the light sending for optical transmitting set 20 receives the process point of deriving light from the fibre core 61 of optical fiber 60 with optical receiver 40, to realize the function of single fiber bi-directional transmission. Understandable, in another embodiment, this fibre-optical splice assembly also can only be made up of fixed muffle, omit porcelain bushing, the hollow tube-shape main body of this fixed muffle forms the access space of directly inserting, arrive plate inner wall face for the fibre core of optical fiber, other structures and the first embodiment are basic identical, therefore do not repeat.
For the ease of being fixedly connected with between fixed muffle 51 and three-way body 10, the position of close three-way body 10 ports of this fixed muffle 51 extends outward the first lateral margin 312, and this first lateral margin 312 can be fixedly mounted on one end port of three-way body 10 by fixed forms such as welding. Understandable, the base plate of this fixed muffle 51 can be inserted into three-way body 10 inside, thereby make loophole more approach optical transmitting set and optical receiver, thereby shortened the distance of fibre-optical splice assembly to the common process point of transmitter and optical receiver light.
In use, the periphery of this fixed muffle 51 is also provided with adapter connector, so that being fixedly connected with of optical fiber 60. As in Figure 3-5, be respectively the schematic diagram that ST joint 70, SC joint 80 and FC joint 90 are set in the periphery of fixed muffle 51; Certainly, also can use LC joint. Further, be also provided with shell in the periphery of fixed muffle 51, to suppress adapter connector and fixed muffle 51.
When assembling, directly the fibre core of optical fiber 60 61 is inserted in the access space of porcelain bushing 52, and utilizes adapter connector locking, assemble simple and reliable. And save the ceramic insertion core of commonly using, shorten the distance of fibre-optical splice assembly 30 to transmitter and optical receiver 40 common focus, reach and must not use lock pin and only need use a fixed muffle 51 can reach the function of single fiber bi-directional transmission, have advantages of simple in structure, main part appearance and size is little, assembly is few, assembly precision is easily controlled, can significantly reduce and manufacture and material cost.
As shown in Figure 6, be the second embodiment of single fiber bi-directional optical fiber transceiver of the present invention, the difference of itself and the first embodiment is: the sidewall in the cylindrical body of fixed muffle 51 extends outward the second lateral margin 313; Between the first lateral margin 312 and the second lateral margin 313, form mounting groove, so that the installation of LC joint 100, as shown in Figure 7. Other structures and a upper embodiment are basic identical, therefore do not repeat. Understandable, also can use in the present embodiment the joints such as ST joint 70 as described in the first embodiment, SC joint 80, FC joint 90.
Above embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement accordingly, can not limit the scope of the invention. All equalizations of doing with the claims in the present invention scope change and modify, and all should belong to the covering scope of the claims in the present invention.
