Description
Technical field
The present invention relates to Networks of Fiber Communications equipment, relate in particular to a kind of single fiber bi-directional optoelectronic transceiver one assembly.
Background technology
Along with the application of fiber optic network is more and more universal, the progressively enforcement of FTTH (Fibre To The Home) project that Fiber to the home especially all over the world, the demand of the single fiber bi-directional assembly that encapsulates for SFP (SFP) on the market also progressively increases thereupon.But because the traditional structure size of single fiber bi-directional assembly is bigger than normal, conflict, adopt the method that increases the connectivity port size to solve usually with the small size encapsulation generation of SFP.This link becomes suddenly big design, and not only profile is not attractive in appearance, and has increased the probability with extraneous damaged in collision greatly.
The structure of traditional single fiber bi-directional assembly as shown in Figure 1, its light path principle figure is shown in 2, after light path enters the optical frames group, in the optical frames group, full emission slide becomes miter angle with input path, behind the light path process total reflection wave plate,, undertaken entering receiving terminal again after the filtering by filter plate then at first through an an angle of 90 degrees total reflection.Receiving terminal adopts the PINTIA assembly, and PIN is a kind of photo-detector, is used for photoelectricity and transforms, and TIA is trans-impedance amplifier (Transimpedance Amplifier); PINTIA is the TO-46 packing forms of standard, and its focal length is 5.8mm, and this just makes single fiber bi-directional assembly minimum widith reach 9.8mm.
The size of the SFP module of standard as shown in Figure 3, its shell sizes is 13.21mm, the inner size that the single fiber bi-directional assembly is installed is 12.1mm.Because the space is narrow and small, the I weld size that traditional single fiber bi-directional assembly is installed back and circuit board produces and conflict, therefore caused need increase connectivity port size problem.
Summary of the invention
The present invention is exactly bigger than normal in order to overcome traditional single fiber bi-directional size of components, and the deficiency with the small size encapsulation of SFP conflicts has proposed a kind of single fiber bi-directional receiver-transmitter integrated module assembly, can adapt to the small size encapsulation of SFP well.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of photoelectric receiver-transmitter integrated module assembly of mono-optical fibre two-way comprises transmitting terminal, receiving terminal, optical frames group, and described transmitting terminal and receiving terminal be arranged in parallel side by side; Described optical frames group comprises the first total reflection slide, the second total reflection slide, and described first total reflection slide and the parallel placement of the second total reflection slide are used for input path is directed into described receiving terminal.
Further, described optical frames group also comprises filter plate, is arranged between described second total reflection slide and the receiving terminal.
Described filter plate also can be arranged between the described first total reflection slide and the second total reflection slide.
Further, described optical frames group also comprises condenser lens, is arranged between the described first total reflection slide and the second total reflection slide.
Described first total reflection slide and input path are miter angle and place.
The present invention is by adding the second total reflection slide in the optical frames group, guaranteeing to make under the unimpeded prerequisite of light path that reflection end and receiving terminal can parallel side by side placements, satisfying under the prerequisite of performance requirement, make the structure of single fiber bi-directional assembly diminish, satisfy the SFP structure of standard on the size fully, adapt to the requirement of SFP miniaturization encapsulation.
The present invention is by being placed with condenser lens between the first total reflection slide and the second total reflection slide, light path can be focused on, simultaneously also reduced the aerial stroke of laser, the laser power that makes receiving terminal receive increases, thereby can improve the sensitivity of reception.Make assembly of the present invention can satisfy performance requirement fully, even its sensitivity, laser power loss ratio traditional structure are more excellent.
The present invention can play filter action by filter plate is set in light path is propagated.
The present invention is miter angle by the first total reflection slide and input path and places, and can make the total reflection of input path generation an angle of 90 degrees, reduces the stroke of laser.
Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

Embodiment
Embodiment one:
The structure chart of a kind of embodiment of the present invention as shown in Figure 4, transmitting terminal 1 and receiving terminal 2 are placed side by side, its light path principle as shown in Figure 5, light path is propagated through optical frames group 3.Optical frames group 3 comprises the first total reflection slide 31, convergent lens 34, the second total reflection slide 33 and filter plate 32.The first total reflection slide 31 and the 33 parallel placements of the second total reflection slide, put into a condenser lens 34 between the two, the first total reflection slide 31 becomes miter angle to place with the incident light direction, put into a filter plate 32 between the second total reflection slide 33 and the receiving terminal 2, this filter plate 32 also can be placed between the first total reflection slide 31 and the second total reflection slide 33.During emission, the emission light path of transmitting terminal directly sees through the first total reflection slide 31 and outwards sends; During reception, the outer light source directive first total reflection slide 31 is through the total reflection of the first total reflection slide 31, inject the second total reflection slide 33 through convergent lens 34 again, through the total reflection of the second total reflection slide 33, carry out filtering by filter plate 34 again, receive by receiving terminal 2.As shown in Figure 6, between the first and second total reflection slides condenser lens 34 is arranged, can focus on the laser of dispersing again, also reduced the aerial stroke of laser simultaneously, the laser power that makes receiving terminal receive increases, thereby has increased receiving sensitivity.

Table 1
Top table 1 is this routine product test parameter list, and in the single fiber bi-directional assembly of traditional structure, the sensitivity of 155M speed can be less than-36dB, and the sensitivity of 1.25Gb speed can be less than-22dB.And can see that from table 1 all less than-22dB, the laser power loss is identical with traditional structure even more excellent in this routine sensitivity.
Embodiment two:
Fig. 7 is the light path scatter graph when not adding condenser lens 34 in the specific embodiment of the invention, under the structure of two total reflection slides of this routine this employing, laser could arrive receiving terminal through twice total reflection, a filtering, aerial stroke increases greatly, make the power of laser be subjected to bigger loss, and because spreading distance is long, average area power reduces, thereby will be inferior to the scheme of embodiment one aspect receiving sensitivity.
Single fiber bi-directional assembly of the present invention satisfies country and international standard fully on main performances such as power, sensitivity, complete and existing SFP standard module compatibility has realized miniaturization under the situation of guaranteed performance on external form.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
