The transmitting light beam λ of 1001 ports1With the incident beam λ ' of the port of optical receiver 20011All process can only pass through Same Wavelength
Band pass filter 3021 on the WDM300 first surfaces of 1270nm light beams, and launch light beam λ and incident beam λ ' and all pass through
In the present embodiment, the size of band pass filter 3021 is 1.4mm* to same thang-kng window 304 on WDM300 second surfaces
1.4mm。
In addition, transmitting light beam λNWith incident beam λ 'NOr transmitting light beam λN+1Incident beam λ 'NBetween spacing<=
2.5mm.It will be understood to those skilled in the art that transmitting light beam and the spacing launched between light beam can be 2.5mm, can also
2.5mm value is less than, such as, spacing can be 0.75mm, 1mm, 1.25mm, 1.5mm, 1.75mm, 2mm or 2.25mm
Etc..
Therefore light emission component 100 and light-receiving component 200 in the permissible range in BOSA spaces must staggered parallel set
Put attachment.Moreover, in order to meet the needs of BOSA can be encapsulated in optical module, below to light emission component 100 and light-receiving
The setting mounting method of component 200 is described further.
Fig. 3 a are the enlarged drawings of light emission component 100 and the set-up mode of light-receiving component 200 in Fig. 2, in the present embodiment
It is assumed that the incident direction of light and reception direction are all along Z-direction.4 generating lasers 1001 in light emission component 100,
1002nd, 1003,1004 and light receiving element in 4 optical receivers 2001,2002,2003,2004 along X-axis staggered parallel
Spread configuration in a column, i.e. their same positions all in Y-axis, but have certain spacing in X-axis.As shown in Figure 3 a,
The ordering that they are set in a column in X-axis is 1001,2001,1002,2002,1003,2003,1004,2004, and
And the space D between each optical transmitting set 100N and optical receiver 200NxnIt is identical, in an example, the He of optical transmitting set 1001
Space D of the optical receiver 2001 in X-axis is 2mm；Optical transmitting set 1001 and optical receiver 2001 are in X-axis in another example
On space D be 1mm.It will be understood to those skilled in the art that any of optical transmitting set 100N and optical receiver 200N is interlocked
Mode arranged in parallel is all within the excursion of the present embodiment, such as optical transmitting set 1001 and light-receiving in the X-axis direction
Space D between device 2001x1Can be with the space D of optical receiver 2001 and optical transmitting set 1002x1’It is incomplete same.
Fig. 3 b show another preferred embodiment of light emission component 100 and the set-up mode of light-receiving component 200, with figure
The difference of example shown in 3a is each the optical transmitting set 100N and optical receiver of light emission component 100 and light-receiving component 200
200N can not be also completely superposed in Y direction, and they in Y-axis except in addition to XZ planes are at regular intervals, equally having certain
Spacing.When mounting the photodiode chip as optical transmitting set Tx chip of laser and as optical receiver Rx, the two
It may be deviated in level height, as shown in Fig. 3 b Y-axis, in this case, optical transmitting set 100N and optical receiver
200N is on the X-Y plane vertical with transmitting light beam and incident beam.In Fig. 3 b XZ planes, optical transmitting set 100N and light connect
Receive, device 200N relative position also incomplete proper alignment, then the two has been spaced in Z-direction, Z to interval scale
Less than or equal to 12mm.For the every group of optical transmitting set and optical receiver of Same Wavelength, such as optical transmitting set 1001 and optical receiver
2001, the space three-dimensional relative position relation of their central points as shown in Fig. 3 b is respectively x, y, z values, by encapsulating BOSA's
Optical mode block size limits, and x, y, z values must meet certain limitation.This BOSA is encapsulated in QSFP modules for example, working as, due to
QSFP optical modules standard size is long 72mm (corresponding to this figure z directions), and wide 18.4mm (corresponding to this figure x directions), high 8.4mm is (right
Should this figure y directions), x, y, z values can be made as defined below：X absolute value | x |<=2mm (is approximately equal to 18.4mm/9), y's
Absolute value | y |<=1.4mm (is equal to 8.4mm/6), and z absolute value range is very wide | z |<=12mm (is equal to 72mm/6), at this moment,
Optical transmitting set 1001 and optical receiver 2001 being smaller than on an x-y plane are equal to 2.5mm.
Fig. 4 is another embodiment of the present utility model.The present embodiment and the difference of embodiment in Fig. 1 are wavelength-division multiplex solutions
Multiplexing structure is changed.Because this main substrate adds the mode of filter plate to be widely used now by each producer, knot
Structure design is also ever-changing, and the utility model is not intended to the design for being related to this structure.No matter the utility model it is emphasized that
How wavelength-division multiplex demux architecture changes, and the light transmitting terminal and receiving terminal (such as Tx1 and Rx1) of every group of co-wavelength must all be handed over
It is misplaced to put, and by same filter plate, reach wavelength-division multiplex and the purpose demultiplexed.
Fig. 5 is the third embodiment of the present utility model.The embodiment is also that wavelength-division multiplex demux architecture is changed
Become.When wavelength-division multiplex demux architecture uses multiple stacked design, light transmitting terminal and receiving terminal can also be adopted accordingly
Take stacked placement；But for every layer of light emission end and receiving terminal, the light transmitting terminal and receiving terminal of every group of co-wavelength
Or it must be staggeredly placed, and by same filter plate, reach wavelength-division multiplex and the purpose demultiplexed.
Shown in Fig. 6 is a single fiber bi-directional optical interface 0001, is a small-sized optical circulator in preferred embodiment.
The principle of optical circulator is that optical signals transmitting terminal enters circulator, can be projected by common port；When optical signals common port enters
During circulator, then projected by receiving terminal.Three ports (transmitting terminal, receiving terminal and common port) of the optical circulator successively respectively with
It is emitted optical position, the light wire jumper interface docking of incident light position and housing.Thus, the logical of component 0002 is demultiplexed by wavelength-division multiplex
Light window projects optical signal after circulator 0001, and the light wire jumper entered by the common port of circulator on BOSA housings 101 connects
Mouth 102；The collimated light signal entered by light wire jumper interface 102, then wavelength-division multiplex demultiplexing group is entered by circulator receiving terminal
Part 0002, received after being demultiplexed for optical receiving end 0003.Hereby it is achieved that same smooth wire jumper interface 102 is to multi-channel wavelength
The up output of flashlight and downlink reception.Further, optical receiving end 0003, light transmitting terminal 0004, wavelength-division multiplex demultiplexing
Component 0002 is all packaged in housing 101, and light wire jumper interface 102 is then bound up with BOSA housings 101.
Fig. 7 is another preferred embodiment of the utility model, realizes that wavelength-division multiplex demultiplexes when using slab guide component
