Technical field
The utility model belongs to the optical communication technology field, specifically, is a kind of single fiber bi-directional optical assembly that is applied to the optical communication technology field.
Background technology
The effect of single fiber bi-directional optical assembly is the conversion that realizes light signal and electric signal, and by realizing the transmission of light signal with the coupling of optical fiber, it is as the core work parts in the optical fiber telecommunications system, and its performance has directly determined the transmission quality of optical fiber communication.
Existing single fiber bi-directional optical assembly as shown in Figure 1, mainly comprises three parts: housing 1 ', support 2 ' and adapter 3 ', wherein, housing 1 ' play a part " skeleton ", all functional assemblies all be directly or indirectly be installed in housing 1 ' on.In the prior art, general used housing 1 ' made by machining mode, its weak point is that to the raw-material utilization factor of housing low and machining period is long etc.: this be because be processed into usually this housing 1 ' structure, used starting material are generally stainless steel and polish cold drawn bar, when the rectangular parallelepiped of processing housing 1 ' centre, need on numerically controlled lathe, bar to be carried out preliminary working earlier, and then utilize milling process that bar is processed into rectangular structure, so just certainly exist the dual waste in material and man-hour, be unfavorable for the reduction of cost and the raising of working (machining) efficiency; Mach production method is not suitable for the structural member making of inner structure complexity in addition, the structural member of inner structure complexity need be resolved into several assemblies and process one by one, is unfavorable for producing in batches.
The utility model content
Technical problem to be solved in the utility model is, provide a kind of and reduce cost, improve working (machining) efficiency and be beneficial to the single fiber bi-directional optical assembly of batch process, realize assembling and the performance of single fiber bi-directional optical assembly by the mode that adopts plastic package, thereby solve the deficiency of prior art.
In order to solve the problems of the technologies described above, a kind of single fiber bi-directional optical assembly of the present utility model comprises housing, laser instrument, detector, 45 ° of filter plates and 0 ° of filter plate; Described housing be provided with the laser instrument body of ccontaining laser instrument, ccontaining detector the detector body, fix first supporting seat of 45 ° of filter plates and fix second supporting seat of 0 ° of filter plate.Described 0 ° of filter plate is between detector and 45 ° of filter plates.In addition, laser instrument, detector, 45 ° of filter plates and 0 ° of filter plate adopt adhering process (for example passing through epoxy resin glue) to be assembled in the housing.
As a further technical scheme, by formed in mould one working of plastics, preferred, described housing is polyetherimide (Polyetherimide below is abbreviated as PEI) plastic casing to described housing on the whole.
As a technical scheme further, described 45 ° of filter plates are with respect to the 45 ° of placements of tilting of the optical axis direction of described laser instrument.As a technical scheme further, described 0 ° of filter plate is with respect to the 0 ° of placement of tilting of the optical axis direction of described laser instrument.
The utility model single fiber bi-directional optical assembly adopts above-mentioned plastic casing structure, its housing adopts the mode of single injection-molded to process, traditional machine work structural member is outer shell integrated, processing capacity is very little, save more man-hour, and one-shot forming, thereby when satisfying the reliability of optical assembly, reduced cost, and can produce in batches.
