Abstract
The utility model provides a novel light emitting device of low cost. The light emitting device comprises a pipe body and an adapter which are welded together. A pipe core is arranged in the pipe body and a ceramic sleeve is fixed in the adapter. According to the novel light emitting device provided by the utility model, a core inserting base and a zirconia inserting core are economized, 30% of cost is saved and the novel light emitting device can satisfy demands of low-level optical module transmission below 155 MB/S 40 km.
Description
Technical field
The utility model relates to a kind of optical element, especially a kind of novel light emitting devices.
Background technology
The optical device industry is more and more higher to the requirement of cost, traditional light emitting devices (TOSA) as shown in Figure 1, comprise adapter 1, Plug pin patch bay 2, body 3, sleeve 4, contact pin 5 and tube core 6, the unitized construction of the ceramic contact pin+sleeve that adopts+metalwork, due to ceramic contact pin unit material and processing cost high, cause device cost to be difficult to descend.
The utility model content
The purpose of this utility model is to provide the low novel light emitting devices of a kind of cost.
Realize the novel light emitting devices of the utility model purpose, comprise the body and the adapter that weld together, be provided with tube core in described body, be fixed with ceramic sleeve in described adapter.
Described body and tube core are by large electric current soldering and sealing together.
Described adapter and ceramic sleeve are gluing fixing.
The entrance of described ceramic sleeve is the outer enlarging of taper.
The tapering of the outer enlarging of described taper is 15 degree.
The beneficial effects of the utility model are as follows: novel light emitting devices of the present utility model, saved lock pin seat and zirconia lock pin, and cost savings 30%, can meet the demand that the following optical module of 155MB/S 40km transmits.
Description of drawings
Fig. 1 is the structural representation of existing light emitting devices.
Fig. 2 is the structural representation of novel light emitting devices of the present utility model.
Embodiment
Embodiment of the present utility model is as follows: as shown in Figure 2, novel light emitting devices of the present utility model, comprise the body 11 and the adapter 10 that weld together, is provided with tube core 12 in described body 11, is fixed with ceramic sleeve 13 in described adapter 10.
Described body 11 and tube core 12 are by large electric current soldering and sealing together.
Described adapter 10 is gluing fixing with ceramic sleeve 13.
The entrance of described ceramic sleeve 13 is the outer enlarging 14 of taper.
The tapering of the outer enlarging 14 of described taper is 15 degree.
The principle of work of novel light emitting devices of the present utility model is as follows: tube core (LD): complete the transformation of electric signal to light signal; Body: fixed laser, and make it and the adapter welding, thereby in conjunction with as a whole; Ceramic sleeve: can closely cooperate with the ceramic contact pin of external smooth wire jumper, the light model can high efficiencyly be transmitted; The tapering of monolateral 15 ° is made in the light contact pin porch of ceramic sleeve, plays the effect that guide pin is inserted; Adapter: fixing ceramic sleeve, make it to make whole light emitting devices become as a whole by with pipe welding, fixing, complete the stable transmission of light signal.Adopt 4.25 and 4.75 two kinds of diameters with the contact pin cover cooperation place of wire jumper, to be fit to simultaneously FC and two kinds of adapters of SC.
Embodiment recited above is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not breaking away under the spiritual prerequisite of the utility model design; various distortion and improvement that the common engineering technical personnel in this area make technical solutions of the utility model, all should fall in the definite protection domain of claims of the present utility model.
