The optical signal is directly transmitted through the internal pre-installed optical fiber via fiber optic flanges 1-4 (without processing by optical components 1-5). The signal is finally exported through another set of fiber optic flanges 1-4 and connected to the external output optical cable to be transmitted to the user end.

[0058] In this embodiment, an optical element 1-5 connected to the fiber optic flange 1-4 can also be added to process the signal.

[0059] Example 6 like Figures 8-10The illustrated passive optical module B includes an optical fiber disk B2 and an optical fiber splitter module B1.

[0060] In this invention, the box body 1-1 is formed by a bottom plate and four side plates connected together. The four side plates include a front side plate, a rear side plate, a left side plate, and a right side plate; wherein the front side plate and the rear side plate are respectively fixed to the optical fiber disk B2.

[0061] Preferably, the fiber optic disk B2 includes a base plate 2-1, a side plate 2-2, and a connecting plate 2-3; The bottom plate 2-1 is connected to one end of the side plate 2-2; There are two side plates 2-2, which are fixed to the front and rear sides of the base plate 2-1 respectively. One end of the side plate 2-2 is connected to the base plate 2-1, and the other end of the side plate 2-2 is connected to the fiber optic splitting module B1 (connected to the front box side plate and the rear box side plate of the box 1-1). The fiber optic splitting module B1 is fixed between the two side plates 2-2. Two ear plates extend from one side (specifically the left side) of the connecting plate 2-3. The ear plates have a second shaft hole, which is adapted to the second rotating shaft A3-3 of the connecting hinge A3.

[0062] In this embodiment, the front and rear sides of the housing 1-1 are respectively provided with threaded connection holes 1-1-3, which are adapted to the side screws 4 or bolts for connecting the housing 1-1 to the fiber optic disc B2. The fiber optic flange 1-4 in the fiber optic splitter module B1 includes one single-hole fiber optic flange 1-4 and two double-hole fiber optic flanges 1-4. The left side of the housing 1-1 is provided with one single-hole flange limiting bayonet 1-1-1 and two double-hole flange limiting bayonet 1-1-2. The housing 1-1 and the cover 1-2 are connected by corner screws 1-4 or bolts (correspondingly, threaded holes are provided at the four corners of the housing 1-1 and the cover 1-2). The fiber optic flange 1-4 and the optical element 1-5 are both finished products.

[0063] In this embodiment, the optical elements 1-5 can be selected according to the optical fiber communication scenario, and can be PLC (planar waveguide device), SPLITTER (optical splitter), or WDM (wavelength division multiplexer), etc.; the connection between optical elements 1-5 and optical fiber flange 1-4 is existing technology and will not be described in detail here. The optical fiber disk B2 is an existing structure and will not be described in detail here.

[0064] Example 7 like Figure 10 The diagram shows an optical passive module assembly structure, specifically optical passive module assembly structure B. The difference between this embodiment and embodiment five is that optical passive module A is replaced with optical passive module B shown in embodiment six. The optical fiber disk B2 of optical passive module B is mounted on the optical fiber disk fixing bracket 8.

[0065] The working principle of this embodiment is as follows: After the optical cable passes through the outside of the optical fiber junction box 11, it first connects with the optical fiber flange 1-4 of the passive optical module B. Through the physical fixation and optical path coupling of the optical fiber flange 1-4, the input light source in the external optical cable is stably introduced into the passive optical module B. The light source entering the module will first be transmitted to the optical element 1-5 on the rear side of the box 1-1. According to the actual communication requirements, the optical element 1-5 will process the light source accordingly. The optical signal processed by the optical element 1-5 will be transmitted again to the output end of the optical fiber flange 1-4 through the preset optical fiber inside the module. Finally, the output optical cable is connected to the output port of the optical fiber flange 1-4 to export the processed optical signal to the designated end (such as communication equipment, user terminal, etc.) for use.

[0066] In this embodiment, optical elements 1-5 may be omitted, and only fiber optic flanges 1-4 may be provided for signal conversion.

[0067] Example 8 like Figure 11 and 12 The illustrated passive optical module C includes an optical fiber disk C10, such as... Figure 12 The connecting hinge B9 is shown; the connecting hinge B9 includes an H-shaped hinge body, a first rotating shaft B9-1 located at one end of the hinge body, and a second rotating shaft B9-2 located at the other end of the hinge body; the first rotating shaft B9-1 is connected to the optical fiber disk C10; the second rotating shaft B9-2 is connected to the optical fiber disk fixing bracket 8.

[0068] In this embodiment, the hinge body is also provided with stress relief holes 9-4 and UP markings 9-5. The stress relief holes 9-4 are used to bear and disperse the stress generated by the deformation of the hinge body during installation, so as to avoid stress concentration leading to breakage. The end of the second rotating shaft B9-2 is also provided with an anti-detachment protrusion 9-3 (to prevent the hinge body from falling off from the fiber optic disc fixing bracket 8). The fiber optic disc C10 is an existing structure, and the matching passive optical module C does not need to be equipped with fiber optic flanges 1-4 and optical elements 1-5. The optical cable can be directly connected to its fiber optic disc C10.

[0069] Example 9 like Figure 12 The diagram shows an optical passive module assembly structure, specifically optical passive module assembly structure C. The difference between this embodiment and embodiment five is that optical passive module A is replaced with optical passive module C shown in embodiment eight.

[0070] In this embodiment, the external input optical cable and the output optical cable are directly connected (usually by fusion splicing or cold splicing) on ​​the fiber optic disc C10 of the passive optical module C, enabling unprocessed direct transmission of optical signals from the input optical cable to the output optical cable. The fiber optic disc C10 protects the directly connected optical fibers.

[0071] Example 10 The difference between this embodiment and embodiment five is that a passive optical module B and / or a passive optical module C are also installed on the optical fiber disk fixing bracket 8.

[0072] In this embodiment, each module is connected to the fiber optic disc fixing bracket 8 via a corresponding connecting hinge, and is installed within the same fiber optic junction box 11 via the fiber optic disc fixing bracket 8. Different functional passive optical modules are integrated within the same fiber optic junction box 11, enabling direct signal processing, connector conversion, or fiber optic splicing, reducing investment in external equipment; additional functional modules can be added later simply by stacking them on the existing bracket, without replacing the junction box.

[0073] Example 11 This embodiment describes the installation method of Embodiment Seven. An installation method for a passive optical module assembly structure: 1. Install the fiber optic disc fixing bracket 8 inside the fiber optic junction box 11, with the fiber optic disc guide groove 8-1 facing the optical cable inlet side of the fiber optic junction box 11. 2. Connect the fiber optic disc fixing bracket 8 to the connecting hinge A3. 3. Pre-assembly of passive optical module B: Fiber optic flange 1-4 and optical element 1-5 are assembled to form fiber optic splitter module B1, and then fiber optic splitter module B1 is connected to fiber optic disc B2: 4. Connect the passive optical module B to the connecting hinge A3; 5. The external optical cable enters from the inlet of the optical fiber junction box 11 and connects with the optical fiber flange 1-4 of the optical fiber splitter module B1, connecting the optical fiber flange 1-4 with the optical element 1-5. 6. Enclosed fiber optic connector box 11.

Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
