Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done explanation in further detail.
The utility model on the basis of conventional optical module, adopts tail optical fiber that the light path of optical module is drawn in order to improve the reliability that the integrated module of optical transceiver (being designated hereinafter simply as optical module) is connected with extraneous optic fibre light path.Wherein, One end of tail optical fiber is connected with the reception optical assembly with the inner emission optical assembly of optical module; Tail optical fiber is passed the shell of optical module, and threaded smooth joint is set, and then adopt the fixing mode of screw thread rotation to realize that optical module is connected with the reliable of extraneous optical fiber at an other end of tail optical fiber.
Come to set forth in detail the concrete establishment structure of said tail fiber type optical module through a concrete embodiment below in conjunction with Fig. 2, Fig. 3.
Embodiment one; Referring to shown in Figure 2; Two optical fiber with certain-length of tail fiber type optical module 5 preferred employings of present embodiment are as tail optical fiber 6; The light signal that optical module 5 internal emission optical assemblies send is drawn, perhaps will be incorporated into through the light signal of extraneous optical fiber input in the inner reception optical assembly of optical module.The length of said tail optical fiber 6 is arranged on about half meter usually, can certainly be random length; Its diameter can be 0.9mm or 2mm, and certainly, present embodiment is not limited in above giving an example.With an end of two tail optical fibers 6 respectively with the inner emission optical assemblies of optical module 5 with receive optical assemblies and connect one to one, its connected mode can be directly with the encapsulation that is coupled of itself and tail optical fiber 6 when making the emission optical assembly and receiving optical assembly; Also can adopt alternate manner will launch optical assembly directs on the tail optical fiber 6 with the light path that receives optical assembly.
