Description

Technical Field

[0001] This utility model relates to the field of multi-channel passive optical splitters, and in particular to a convenient passive optical device integration device for highways. Background Technology

[0002] Currently, the integrated device for portable passive optical equipment on highways mainly adopts planar optical waveguide splitter technology. PLC optical splitter is a micro-optical component product that uses photolithography to form optical waveguides on dielectric or semiconductor substrates to achieve branching and distribution functions. This technology has the advantages of clear splitting principle, stable performance, and easy integration.

[0003] In terms of device design, a common approach is to use a pluggable module and bridging tube structure. The pluggable module includes components such as a ceramic ferrule, a multi-core optical fiber, a bridging tube, and a lens. The ceramic ferrule has a through-hole, and the multi-core optical fiber is placed inside the through-hole to form a mating end face with the ceramic ferrule. The bridging tube has a bridging hole running through it along the optical path. The ceramic ferrule and the lens are opposite each other and fixedly assembled in the bridging hole. This design allows the passive optical splitter to be plugged and unplugged more easily with other devices, improving the convenience and durability of plugging and unplugging.

[0004] In addition, to further optimize the performance of the pluggable multi-channel passive optical splitter, a variety of fixing and connection technologies are adopted. For example, by setting up easily replaceable fixing components, bolts and guide rods are used to fix the connector, solving the problem of inconvenient disassembly and assembly of the connector. At the same time, elastic elements such as telescopic springs are used to make the connection tighter, improving the stability and reliability of the device.

[0005] In summary, current highway-compatible passive optical equipment integration devices are relatively mature in technology, with advantages such as easy plugging and unplugging, stable performance, and easy integration, and are widely used in fiber optic communication networks.

[0042] Excellent optical performance: The optimized design of the optical splitter body and the application of optical lenses in the pluggable interface module effectively reduce the transmission loss and coupling loss of optical signals, and improve the overall optical performance of the optical splitter.

[0043] High flexibility: Optical splitter main bodies with different splitting ratios and number of channels can be selected according to actual needs, and with plug-in interface modules, flexible optical signal distribution schemes can be realized to meet the needs of different optical communication application scenarios.

[0044] This portable passive optical equipment integration device for highways mainly includes an optical splitter body, a pluggable interface module, and a housing. The optical splitter body is used to realize the optical signal splitting function, the pluggable interface module is used to connect external optical fibers, and the housing serves to protect and fix the internal components.

[0045] The optical splitter body is fabricated using planar optical waveguide (PLC) technology and has multiple input and output ports, capable of distributing the input optical signal to each output port according to a certain splitting ratio. In this embodiment, the optical splitter body has 1 input port and 8 output ports, with a splitting ratio of 1:8. The waveguide structure inside the optical splitter body is optimized to reduce optical signal transmission loss and crosstalk.

[0046] Plug-in Interface Module: The plug-in interface module includes input and output interfaces. The input interface is used to connect external input optical fibers, and the output interface is used to connect external output optical fibers. The plug-in interface module adopts a ceramic ferrule structure. The ceramic ferrule has high precision and good stability, ensuring accurate fiber optic mating and reliable connection. Capillary holes are provided within the ceramic ferrule; the optical fiber is inserted and fixed through these holes, ensuring that the fiber's position within the ferrule is not affected by the external environment.

Internal slots are provided for securing the optical splitter body and pluggable interface modules. Ventilation holes are also provided on the housing to ensure adequate heat dissipation during operation.

[0048] Working principle:

[0049] When the external input optical fiber is connected to the optical splitter body through the input interface of the pluggable interface module, the optical signal enters the optical splitter body from the input port. The optical splitter body, based on its internal waveguide structure and splitting ratio, distributes the optical signal to each output port. Then, the optical signals from each output port are transmitted to the external output optical fiber through the output interface of the pluggable interface module, thus achieving split-path transmission of the optical signal. Throughout this process, the ceramic ferrule structure and optical lenses of the pluggable interface module ensure stable optical signal transmission and efficient coupling. Detailed Implementation

[0051] Fabrication of the optical splitter body: Planar optical waveguide structures are fabricated on a silicon substrate using processes such as photolithography and etching to form the optical splitter body with a specific splitting ratio. During the fabrication process, the dimensional accuracy and surface quality of the waveguide are strictly controlled to reduce transmission loss and crosstalk of the optical signal.

[0052] Assemble the pluggable interface module: The ceramic ferrule is precision-machined to ensure its internal capillary aperture size precisely matches the outer diameter of the optical fiber. The optical fiber is inserted into the capillary aperture and secured with adhesive. Then, the ceramic ferrule with the optical fiber is assembled with the optical lens, ensuring the lens and fiber axes are aligned for optimal optical coupling.

[0053] Assembly: Install the prefabricated optical splitter body into the slot inside the housing and secure it firmly. Next, connect the assembled pluggable interface module to the optical splitter body, ensuring a tight connection and smooth optical signal transmission. Finally, seal the housing, completing the assembly of the entire highway portable passive optical equipment integration device.

[0054] Testing and Debugging: Perform optical performance tests on the assembled optical splitter unit, including testing parameters such as insertion loss, splitting ratio accuracy, and return loss. Based on the test results, perform debugging, adjusting or reassembling any parts that do not meet the requirements until the performance of the optical splitter unit meets the design requirements.

[0055] The working principle of the portable passive optical device integration device for highways provided by this utility model is as follows:

[0056] In use, when disassembling the multiple first pluggable interface modules 3 or multiple second pluggable interface modules 8 on the optical splitter body 2 and the housing 7, the multiple first pluggable interface modules 3 or multiple second pluggable interface modules 8 can be separated from the optical splitter body 2 or the housing 7 by pulling them apart.

The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0061] Specifically, the difference in the second embodiment of this application regarding the highway portable passive optical device integration device is that a disassembly assembly 11 is provided between the optical splitter body 2 and the plurality of first pluggable interface modules 3. The disassembly assembly 11 includes a rectangular disassembly frame 111, two positioning blocks 112, two positioning grooves 113, two rubber pads 114, and a plurality of threaded bolts 115. The two positioning blocks 112 are respectively connected to the left and right sides of the rectangular disassembly frame 111, the two positioning grooves 113 are opened on the surface of the optical splitter body 2, and the two rubber pads 114 are respectively disposed on the top and bottom of the rectangular disassembly frame 111.

The use of the positioning block 112 and the positioning slot 113 facilitates the positioning between the rectangular disassembly frame 111 and the optical splitter body 2, and also facilitates the installation between the rectangular disassembly frame 111 and the optical splitter body 2 by the threaded bolt 115.

[0064] The working principle of the portable passive optical device integration device for highways provided by this utility model is as follows:

[0065] When using the optical splitter body 2, to disassemble the first pluggable interface module 3, first remove the multiple threaded bolts 115 between the two positioning blocks 112 and the optical splitter body 2. After the multiple threaded bolts 115 are removed, pull the optical splitter body 2 to drive the rectangular disassembly frame 111 to pull outward. When the rectangular disassembly frame 111 is pulled outward, it causes the positioning blocks 112 on both sides to separate from the positioning grooves 113 on the surface of the optical splitter body 2, so that the first pluggable interface module 3 can be removed and replaced.
