Description

Technical Field

[0001] This utility model relates to the field of fiber optic connector design technology, and in particular to a multifunctional loop jumper connector assembly. Background Technology

[0002] With the development of modern communication technology, the high speed and low cost of fiber optic communication have brought many conveniences to people's production, life, and scientific research. Therefore, optical patch cords are widely used in communication equipment rooms and equipment connections. However, when these optical patch cords are widely used in equipment rooms, chassis, and equipment connections, situations often arise where two adjacent ports need to be interconnected for testing or signal conversion. In existing technology, a fiber optic distribution box with LC dual-connector ports on the front panel, if two adjacent ports A and B need to be interconnected for testing, previously, ordinary LC optical patch cords were used for connection. If the product length was relatively long, it would be inconvenient to carry and use on-site. Later, researchers developed shorter and simpler loop patch cords and loop patch cord boxes (usually containing 0.9mm OD fiber optic cable or 0.25mm fiber optic cable), making them neater, more aesthetically pleasing, and easier to carry and use. However, in current high-density and complex application scenarios, the application and construction space may be very limited, and this product cannot meet the requirements. Therefore, further improvements are needed. Utility Model Content

[0014] Furthermore, the reflective component includes a dual-fiber pigtail assembly and a self-focusing lens and filter mounted on one end of the dual-fiber pigtail. The dual-fiber pigtail assembly is connected to the ferrule assembly of the LC connector via two optical fibers.

[0053] In this embodiment, the tailpipe structure 8 is provided with a first fixing part 801 and a second fixing part 802.

[0060] like Figure 6-12 As shown, a method for manufacturing a multifunctional loop jumper connector assembly includes the following steps:

[0061] X1: Creating Patch Components

[0062] like Figure 6 As shown, the plane of the filter 11 coated with the total reflection film is attached to the plane of the self-focusing lens 10. After wrapping the joint with UV100 glue, it is dried under a 365nm ultraviolet lamp and then placed in a high-temperature oven for secondary curing to obtain the patch assembly.

[0063] X2: Create a reflection component

[0064] like Figure 7 As shown, the dual-fiber pigtail assembly 9 and the patch assembly are coupled under a reflective coupling machine, the gap and loss value are adjusted, and then cured again to obtain the reflective assembly 4;

[0065] X3: Fabricating Connector Components

[0066] like Figure 8As shown, the two optical fibers (optical fiber 4A and optical fiber 4B) of the reflective component 4 are cut to a certain length, and then a 125um optical fiber is stripped out and inserted into the LC connector 3 and the ferrule assembly 303 which are filled with 353ND glue, respectively. They are then baked and cured at high temperature, and the end face of the LC ferrule assembly 303 is ground. The end face of the ferrule assembly 303 is inspected and its performance is tested. After completion, LC dust caps 305 are put on the ferrule assembly 303 to obtain the connector assembly.

[0067] X4: Connector assembly

[0068] like Figure 9 As shown, the base 1 is inserted into one end of the connector assembly 4, and then the two LC connectors 3 are respectively inserted into the first receiving groove 101 and the second receiving groove 102 corresponding to the base 1. The two optical fibers are straightened and inserted into the fiber guide groove 104, and then the cover plate 2 is put on to lock the base 1.

[0069] X5: Crimping the connector assembly

[0070] like Figure 10 As shown, inject 353ND adhesive to a depth of about 10mm into the large opening of the crimping metal tube 6. Insert the optical fiber on the right side of the assembled connector assembly and the reflective component 4 into the crimping metal tube 6. Fit one end of the base 1 onto the large opening of the crimping metal tube 6. Use crimping pliers to press the crimping metal tube 6 tightly. Place part of the crimping metal tube 6 in an 80° oven for heating to cure the 353ND adhesive and the reflective component 4 inside.

[0071] X6: Curing

[0072] like Figure 11 As shown, the tail sleeve assembly 7 is fitted onto the press-fit metal tube 6 and placed at the stop position of the base 1 to obtain the finished connector assembly.

[0073] In this embodiment, the specific steps of step X2 are as follows:

[0074] The dual-fiber pigtail and the patch assembly are coupled under a reflective coupling machine. The gap is adjusted, and the loss value is adjusted to ≤0.2dB. UV glue 10 is applied to the outer ring of the gap between the dual-fiber pigtail and the patch assembly. The assembly is dried under a 365nm UV lamp and then placed in a high-temperature oven for secondary curing to obtain reflective component 4.

[0075] If energy distribution or wavelength selection is required in this application, a filter with the corresponding coating function can be selected. The rest of the process is exactly the same, only the selection and setting of test parameters need to be noted.

[0076] This utility model takes into account practical application scenarios and combines a reflective component with a coated filter with a traditional connector structure. The overall design length is 57mm, which is much shorter than the length of conventional LC loop jumpers on the market and more compact than box-type packaging, with obvious advantages.

[0077] In addition, this utility model product also has a variety of other functions and can be manufactured according to actual needs to meet different application requirements (such as...). Figure 13 As shown):

[0078] (1) When it is required that all optical signals input from Connector A be transmitted to Connector B, a filter with a total reflection film can be used to achieve this function. In this case, the design is exactly the same as the function of a conventional loop jumper.

[0079] (2) When only 20% (or more percentages, such as 90%, 80%, 70%, 60%, ..., 10%) of the optical signal energy input from Connector A is required to be transmitted to Connector B, a 20% reflectance splitting ratio coated filter can be used to achieve this, and other percentages can be selected.

[0080] (3) When only a portion of the wavelength of the optical signal input from Connector A needs to be transmitted to Connector B, a coated filter that can filter that specific wavelength can be selected. For example, if the optical signal input from Connector A is a broadband optical signal with a wavelength range of 1260–1650 nm, and Connector B is required to receive only the wavelength range of 1420–1560 nm, then a filter coated to reflect the wavelength range of 1420–1560 nm can be selected. Filtering functions for other wavelength bands can be selected similarly.

[0081] When the optical signal transmitted from the fiber optic cable of Connector A passes through the self-focusing lens and reaches the filter layer, since a total internal reflection film is selected at this time, the entire optical signal is returned and converged through the self-focusing lens into another fiber optic cable for transmission to the output of Connector B. The loss can be controlled within 0.5dB.

[0082] This utility model provides a multifunctional loop patch cord connector assembly with advantages such as ease of use, simple operation, and effective improvement in fiber optic ferrule cleaning efficiency. This application, through a unique structural design that comprehensively considers practical application scenarios, combines a reflective component 4 with a coated filter 11 with the connector structure. The overall design length is 57mm, significantly shorter than existing conventional LC loop patch cords on the market, and more compact than box-type packaging, offering clear advantages. If energy distribution or wavelength selection is required, selecting the filter 11 with the corresponding coating function is sufficient, making operation very convenient. This application effectively improves product quality; therefore, it has significant economic and practical value.
