Description
Technical field
The present invention relates to a kind of wavelength divided duplexing equipment, particularly relate to a kind of structure is simplified, volume is little wavelength divided duplexing equipment and method for packing.
Background technology
As shown in Figure 1, be existing a kind of wavelength divided duplexing equipment, comprise a filter 1, one first gradually changed refractive index lens 2, one second gradually changed refractive index lens 3, a pair of fibre-optic catheter 4, a single fiber conduit 5, one can affixed this filter 1 can affixed these first gradually changed refractive index lens 2 and the thermosetting glue-line 601 of this pair fibre-optic catheter 4 with the thermosetting glue-line 6 of these first and second gradually changed refractive index lens 2,3,, and one can affixed these second gradually changed refractive index lens 3 and the thermosetting glue-line 602 of this single fiber conduit 5.This wavelength divided duplexing equipment during fabrication, be utilize earlier this thermosetting glue-line 6 with this filter 1 with this first, two refractive index progressive lens 2,3 affixed being integral, then, adjust the relative position of this pair fibre-optic catheter 4 and these first gradually changed refractive index lens 2, after making this pair fibre-optic catheter 4 obtain minimum reflection loss, utilize this thermosetting glue-line 601 with these first gradually changed refractive index lens 2 and this pair fibre-optic catheter 4 affixed being integral again, at last, adjust the relative position of this single fiber conduit 5 and these second gradually changed refractive index lens 3, after making this single fiber conduit 5 obtain minimum insertion loss, utilize this thermosetting glue-line 602 again with these second gradually changed refractive index lens 3 and these single fiber conduit 5 affixed being integral.
So, this wavelength divided duplexing equipment can be for being used for combination or separating the light signal with different wave length, but, when actual manufacturing is used, because these thermosetting glue-lines 6,601,602 curing reaction time is longer, therefore, in being subjected to the process of hot curing, these thermosetting glue-lines 6,601,602 jelly tend to infiltrate this filter 1 with this first, two refractive index progressive lens 2, between 3 the opposing end surface, or between the opposing end surface of these first gradually changed refractive index lens 2 and this pair fibre-optic catheter 4, again or between the opposing end surface of these second gradually changed refractive index lens 3 and this single fiber conduit 5, and the transmission of light signal is exerted an adverse impact.
As shown in Figure 2, be existing another kind of wavelength divided duplexing equipment, comprise one and have three assembly welding holes 701,702,703 passage steel pipe 7, one is installed in this passage steel pipe 7 and has a collar 801, the filter unit 8 of one filter 802, one can be installed in the two fiber optic collimators unit 9 in this passage steel pipe 7, one can be installed in the single fiber collimation unit 101 in this passage steel pipe 7, reach an outer steel pipe 106 that is installed in outside this passage steel pipe 7, this pair fiber optic collimator unit 9 has one first gradually changed refractive index lens 901, a pair of fibre-optic catheter 902, one glass tube 903, reach straight steel pipe 904 surely, this single fiber collimation unit 101 has one second gradually changed refractive index lens 102, one single fiber conduit 103, one glass tube 104 reaches straight steel pipe 105 surely.This wavelength divided duplexing equipment during fabrication, be to utilize jelly to be fixed in contacting between the side face of this collar 801 and this filter 802 earlier, again this collar 801 is inserted this passage steel pipe 7, and borrow scolder (tin or lead) to insert in these welding holes 701, and this collar 801 is welded together with this passage steel pipe 7; Then, carry out the assembly of this pair fiber optic collimator unit 9, promptly, after this pair fibre-optic catheter 902 in being inserted in this glass tube 903 obtains minimum reflection loss with these first gradually changed refractive index lens, 901 adjustment relative positions to this pair fiber optic collimator unit 9, utilize jelly that these first gradually changed refractive index lens 901, this pair fibre-optic catheter 902 are fixed in this glass tube 903, and utilize jelly that this glass tube 903 is fixed in this collimation steel pipe 904, relend that scolders in these welding holes 702 should collimate steel pipe 904 and this passage steel pipe 7 welds together by inserting; Then, carry out the assembly of this single fiber collimation unit 101, promptly, this single fiber conduit 103 in being inserted in this glass tube 104 is adjusted relative position to these second gradually changed refractive index lens, 102 acquisition collimated rays with these second gradually changed refractive index lens 102, utilize jelly with these second gradually changed refractive index lens 102, this single fiber conduit 103 is fixed in this glass tube 104, and utilize jelly that this glass tube 104 is fixed in this collimation steel pipe 105, and, after this single fiber collimation unit 101 inserted this passage steel pipe 7 and obtains minimum insertion loss, these welding holes 703 interior scolders should collimate steel pipe 105 and this channel steel pipe 7 welds together by inserting; At last, 7 groups of this channel steel pipes are gone in this outer steel pipe 106, and should outer steel pipe 106 closed at both ends.
Though this kind wavelength divided duplexing equipment also is available for combination or separates the light signal with different wave length,, when actual manufacturing was used, this wavelength divided duplexing equipment but had following disappearance:
One, although this kind wavelength divided duplexing equipment can improve the problem between above-mentioned wavelength divided duplexing equipment thermosetting jelly infiltration element opposing end surface, but, but must increase this collar 801 and locate this filter 802, and these glass tubes 903 of increase, 104 with these the collimation steel pipes 904,105 locate this first gradually changed refractive index lens 901, this pair fibre-optic catheter 902 and these second gradually changed refractive index lens 102, this single fiber conduit 103, and increase this collimation steel pipe 7 and come this filter unit 8 of solid welding, this pair fiber optic collimator unit 9 and this single fiber collimation unit 101, in addition, this is first years old, two refractive index progressive lens 901, the 102nd, be with this filter 802 and separate setting, therefore, this kind wavelength divided duplexing equipment is the member complexity not only, and length in the axial direction all can increase with the width that the footpath makes progress, and causes volume to increase.
Two, this filter unit 8, this pair fiber optic collimator unit 9 are could collimate steel pipe 7 affixed being integral with this via welding with this single fiber collimation unit 101, so, not only can increase the encapsulation time of this kind wavelength divided duplexing equipment, and the high temperature that produces during welding (for example more may destroy interconnected interelement jelly, jelly between these first gradually changed refractive index lens 901, this pair fibre-optic catheter 902 and this glass tube 903), cause interconnected element to produce and relatively move, and influence the transmission of light signal.
Three, after this kind wavelength divided duplexing equipment must be assembled this filter unit 8, this pair fiber optic collimator unit 9 and this single fiber collimation unit 101 respectively earlier and finish, just can carry out further overall package, so, trouble not only, and can increase the worker of encapsulation procedure the time.
