Accompanying drawing explanation
Fig. 1 is that structure of the present utility model forms schematic diagram.
Fig. 2 is cross section view of the present utility model.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, Miniature optical fiber amplifier, including cover plate 1 light path devices 2 module base 3 printed circuit board (PCB) 4 photodetector 5 laser instrument 6 electrical interface 7 heat-shrinkable T bush 8 etc..This utility model is the erbium-doped fiber amplifier that a kind of structure is improved, and in Fig. 1, Er-doped fiber is not drawn into；
The housing of this Miniature optical fiber amplifier is made up of cover plate 1 module base 3, has accommodation space in module base 3；Circuit devcie and light path devices 2 it is provided with in housing；Cover plate 1 is screwed on module base 3, and the overall dimensions of housing only has 55 × 35 × 10 mm, can meet the follow-on 100G optical transmission system shape requirement to EDFA.
In order to realize the miniaturization of amplifier, light path devices 2 is placed on printed circuit board (PCB) 4 electronic devices and components by whole product indirectly, in order to prevent short circuit, nonconducting optical fiber fusion welding point heat-shrinkable T bush 8 is first placed on printed circuit board (PCB) 4, then light path devices 2 is positioned on heat-shrinkable T bush 8, so can farthest save space.Concrete structure is as follows:
