Description
Technical field
The invention belongs to light transmitting-receiving unification module and the device arts of optical communication field, particularly relate to a kind of pluggable type adapter assembly for collimated light path coupling.
Background technology
In optical communication field, collimated light path uses C-LENS (spherical lens) or G-LENS (gradual index lens) collimator structure to realize usually, Fig. 1 is the schematic cross-section of a kind of typical C-LENS collimating apparatus in prior art, as shown in Figure 1, this C-LENS collimating apparatus optical fiber 302 is through glass capillary 301, and grind to form certain angle, then be coupled with C-LENS 303, the diverging light of outgoing in optical fiber 302 is become directional light, glass bushing 304 is enclosed within outside C-LENS 303 and glass capillary 301, with glue, all parts is fixed together.This collimator structure is very ripe, and collimating effect is good, but collimating apparatus is in the market all tail fiber type, is suitable only for the encapsulation of tail fiber type optical assembly, cannot be applied in the light transmitting or receiving unit needing pluggable type adapter.And most optical transceiver module used requires to possess pluggable optical interface, such as LC type optical interface and SC optical interface etc., this just requires the utilizing emitted light assembly TOSA in optical transceiver module and receives optical assembly ROSA to use tail fiber type to encapsulate, and pluggable type adapter must be used to carry out component package.
Pluggable type adapter assembly first requirement can carry out good plug with optical patchcord and is connected, and ensures low junction loss; Secondly requirement can carry out optically-coupled with the body cooperation of optical assembly, after being coupled to the position met the demands, utilize laser welding process to weld together with optical assembly body; In addition pluggable type adapter assembly also requires to ensure enough physical strengths, can not cause optical path change under temperature or external force are exerted one's influence.
Be illustrated in figure 2 the schematic cross-section of the pluggable type adapter of a kind of conventional LC type in prior art, as shown in Figure 2, the pluggable type adapter 101 of LC type comprises: the ceramic insertion core 102 being inside installed with optical fiber 103, ceramic sleeve 105 and seam part 106, and ceramic insertion core 102, optical fiber 103, ceramic sleeve 105 and seam part 106 periphery adapter metalwork 104.The pluggable type adapter 101 of LC type meets LC interface relevant criterion, when conventional LC optical patchcord inserts from seam part 106 end, can ensure that optical patchcord realizes low-loss smoothly with the optical fiber 103 in ceramic insertion core 102 and is connected.
Be illustrated in figure 3 reception optical assembly ROSA (the Receiver OpticalSubassembly that in prior art, a kind of conventional TO-Can encapsulates, light-receiving secondary module) schematic cross-section, as shown in Figure 3, receive in optical assembly ROSA, it is inner that photo detector chip 201 is mounted on TO seat 202, TO cap 203 and body 204 all soldering and sealing on TO seat 202.It is welded together that LC type pluggable type adapter 101 and body 203 pass through laser welding process afterwards in coupling.The overall light path of this structure be light from optical fiber 103 outgoing ceramic insertion core 102, emergent light is diverging light, and the lens on TO cap 202 become converging light, is then coupled into photo detector chip 201.For utilizing emitted light assembly, change photo detector chip 201 into chip of laser, light is by chip of laser outgoing, and light path, along diagram light path reversible direction, enters into the optical fiber 103 of ceramic insertion core 102.Therefore, conventional at present pluggable type adapter is all as Path of Convergent Rays or disperses light path use in light path application.
In recent years, optical transceiver module is more and more higher to integration level necessitates, and light is launched or receiving unit requires integrated more function and unit, causes the light path in optical assembly more and more longer.As above-mentioned Path of Convergent Rays, limitting by the focal length of lens, light path cannot realize the requirement more grown, and therefore needs to adopt collimated light path design.Collimated light less parallel light, possesses plurality of advantages: can propagate longer light path and still ensure that hot spot does not expand; And do not affect by focal length, insensitive to component installation location precision; In collimated light path, add some function element such as isolator etc. affects very little on light path; In addition collimated light path also has another advantage, and exactly when two bundle collimated light paths intercouple, coupling tolerance is very large, and insensitive to positional precision, man-hour, work efficiency was fast; These advantages are all well suited for this light needing light path very long and launch or the requirement of receiving unit.
Be illustrated in figure 4 the schematic cross-section of a kind of conventional utilizing emitted light assembly based on collimated light path in prior art, it is inner that chip of laser 402 is mounted on shell 401, collimated light is become through the first collimation lens 403 from the light of chip of laser 402 outgoing, collimated light is assembled through the second collimation lens 404 again, through the window of shell 401 sidewall, enter into the optical fiber 103 of the pluggable type adapter 101 of LC type.Elements all in shell 401 first first must be installed and fix by this structure, and then shell 401 and the pluggable type adapter 101 of LC type are coupled, and remain Path of Convergent Rays like this during actual coupling from the light of shell 401 outgoing.The coupling tolerance that Path of Convergent Rays is coupled to LC type pluggable type adapter 101 is less, and the postwelding displacement brought due to welding technology when the pluggable type adapter 101 of LC type and body 401 weld together like this can have impact to light path.So although this structure is based on collimated light path design, in this step of adapter assembly coupling welding, essence remains the same with conventional optical assembly coupling, belong to Path of Convergent Rays coupling, when failing to have given play to collimated light path parallel coupling, coupling efficiency is high, and coupling difficulty is low, the large advantage of coupling tolerance.And once the installation accuracy of the first collimation lens 403 and the second collimation lens 404 is uncontrollable very accurate, also can make a big impact to coupling efficiency.In addition, distant between this structure second collimation lens 404 and optical fiber 103, causes the spot diameter of collimated light path must be very large, must use the optical assembly of small light spot collimated light path, cannot adopt this structure for some.
