Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, and in particular to an optical port component and an optical module. Background Technology

[0002] The optical port of existing optical modules requires a Mechanical Transfer (MT) ferrule. The MT ferrule is used to couple the optical port of the optical module to external devices. When limiting the MT ferrule in the existing optical module housing, discrete devices on the optical module housing are usually used to fix and limit the MT ferrule. However, discrete devices often occupy more space on the optical module housing. At the same time, the position of discrete devices on the optical module housing will also have errors, making it difficult to guarantee the accuracy of the position of discrete devices. As a result, when the discrete devices limit and fix the MT ferrule, the position of the MT ferrule will also have a large error, causing the transmission performance and coupling efficiency of the MT ferrule to fall short of expectations.

[0003] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0023] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1: Embodiment 1 of this utility model provides an optical port assembly, such as... Figure 1 and Figure 2 As shown, it includes: adapter 1, wherein: the adapter 1 includes: reference block 11, first claw 12 and second claw 13; the first claw 12 and the second claw 13 are both located on the first side 111 of the reference block 11, the reference block 11, the first claw 12 and the second claw 13 are integrally formed, and the MT ferrule 3 is clamped between the first claw 12 and the second claw 13; the first claw 12 and the second claw 13 are used to limit the MT ferrule 3 and prevent the MT ferrule 3 from coming out from between the first claw 12 and the second claw 13.

[0025] like Figure 3 As shown, the optical port assembly is housed within an optical module, which also includes a housing 2. One or more receiving slots 21 are provided in the housing 2, and the adapter 1 is disposed in the receiving slot 21. The first side 111 of the adapter 1 faces the electrical port 23 of the housing 2.

[0026] like Figures 1-5As shown, in this embodiment, adapter 1 is used to insert MT ferrule 3, limiting the MT ferrule 3 within adapter 1, and adapter 1 with MT ferrule 3 inserted is placed in receiving groove 21 of housing 2. Housing 2 is the outer shell of optical module, and receiving groove 21 is located at optical port 25 of housing 2. One end of MT ferrule 3 serves as optical port 25 of optical module, and the other end of housing 2 serves as electrical port 23 of optical module. Reference block 11 is located in the middle of adapter 1. The two sides of reference block 11 are used as platforms to set different structural components. The side of reference block 11 facing electrical port 23 is the first side 111, and the side of reference block 11 facing optical port 25 is the second side 112. The first claw 12 and the second claw 13 both extend outward from the first side 111. When the MT ferrule 3 is inserted into the adapter 1, the first claw 12 and the second claw 13 are located on both sides of the MT ferrule 3, limiting the MT ferrule 3. A positioning clamp 5 is provided on the second side 112, which is used to fix the external device and the housing 2 relative to each other when the external device and the MT ferrule 3 at the optical port 25 are mated.

[0027] In one embodiment, the first claw 12 and the second claw 13 both extend vertically outward from the first side 111; or, the first claw 12 and the second claw 13 both extend outward at a preset angle from the first side 111. The angle of inclination can be determined according to the actual situation and is not specifically limited here.

[0028] like Figure 4 As shown, the reference block 11 is also provided with an assembly port 14, which connects from the first side 111 of the reference block 11 to the second side 112 of the reference block 11. The assembly port 14 is used to insert the MT ferrule 3. The first claw 12 is located on one side of the assembly port 14, and the second claw 13 is located on the other side of the assembly port 14.

[0029] Furthermore, in this embodiment, the first claw 12 and the second claw 13 need to limit the two sides of the MT ferrule 3, and also need to limit the MT ferrule 3 in the horizontal direction. Therefore, this embodiment also involves the following design: Figure 6As shown, the first claw 12 includes a first extension 121 and a first limiting hook 122, and the second claw 13 includes a second extension 131 and a second limiting hook 132. Specifically: one end of the first extension 121 is disposed on the first side 111 and extends outward; the first limiting hook 122 is disposed at the other end of the first extension 121 and faces the inner side of the first extension 121; one end of the second extension 131 is disposed on the first side 111 and extends outward; the second limiting hook 132 is disposed at the other end of the second extension 131 and faces the inner side of the second extension 131; the first limiting hook 122 and the second limiting hook 132 are used to limit the outer end face of the MT ferrule 3.

[0030] Furthermore, such as Figure 6 As shown, this embodiment also involves the following design for the first limiting hook 122 and the second limiting hook 132.

[0031] The first limiting hook 122 has a first buffer slope 122-1 on the side facing the electrical port 23, and the first buffer slope 122-1 is inclined towards the electrical port 23. The side of the first limiting hook 122 facing the optical port 25 has a first right angle surface 122-2. The second limiting hook 132 has a second buffer slope 132-1 on the side facing the electrical port 23, and the second buffer slope 132-1 is inclined towards the electrical port 23. The side of the second limiting hook 132 facing the optical port 25 has a second right angle surface 132-2.

[0032] When the MT ferrule 3 is clamped between the first claw 12 and the second claw 13, the first right-angled surface 122-2 and the second right-angled surface 132-2 are used to fit against the outer end face of the MT ferrule 3 to prevent the MT ferrule 3 from coming out between the first claw 12 and the second claw 13.

[0033] In this embodiment, the first limiting hook 122 is provided with a first buffer slope 122-1, which is inclined towards the electrical port 23, and the side of the first limiting hook 122 facing the optical port 25 is a first right-angled surface 122-2; the second limiting hook 132 is provided with a second buffer slope 132-1, which is inclined towards the electrical port 23, and the side of the second limiting hook 132 facing the optical port 25 is a second right-angled surface 132-2; when the MT ferrule 3 is inserted horizontally into the assembly port 14 of the first side surface 111, the MT ferrule 3 moves along the first buffer slope 122-1. 22-1 and the second buffer slope 132-1 press the first limiting hook 122 and the second limiting hook 132 outwards, and the first extension 121 and the second extension 131 deform outwards. The end of the MT plug 3 facing the electrical port 23 is a step 31, and the step 31 protrudes relative to the outer periphery of the MT plug 3. When the MT plug 3 is fully inserted into the assembly port 14, the first right angle surface 122-2 and the second right angle surface 132-2 abut against the outer end face of the step 31. The first right angle surface 122-2 and the second right angle surface 132-2 are used to prevent the MT plug 3 from coming out of the assembly port 14 and to limit the MT plug 3.

[0034] Furthermore, in this embodiment, the MT ferrule 3 is limited by the first right-angled surface 122-2 and the second right-angled surface 132-2 to prevent the MT ferrule 3 from coming out of the assembly port 14. In addition, it is also necessary to limit the depth of the MT ferrule 3 inserted into the assembly port 14. Therefore, this embodiment also involves the following design: like Figure 7 As shown, the first side 111 is also provided with one or more limiting platforms 16, wherein: the one or more limiting platforms 16 are distributed on the periphery of the assembly port 14, and the limiting platforms 16 abut against the step 31 on the outer side of the MT ferrule 3.

[0035] In this embodiment, two limiting platforms 16 can be provided on one side of the assembly port 14 and two limiting platforms 16 can be provided on the other side of the assembly port 14. Different limiting platforms 16 are used to limit the end face of the step 31 facing the light port 25.

[0036] Example 2: Based on the optical port component of Embodiment 1 above, this embodiment provides an optical module including the optical port component.

[0037] like Figure 3 and Figure 8 As shown, the optical module also includes a housing 2, in which one or more receiving slots 21 are provided, and the adapter 1 is disposed in the receiving slot 21, with the first side 111 of the adapter 1 facing the electrical port 23 of the housing 2.

[0038] Furthermore, the structure of the receiving groove 21 in the casing 2 needs to be adapted to the structure of the adapter 1 in order to limit and install the adapter 1. Therefore, this embodiment also involves the following design: like Figure 8 and Figure 9 As shown, the receiving slot 21 includes a cable guide slot 211, a placement slot 212, and a limiting slot 213 that are connected sequentially from the electrical port direction to the optical port direction. The cable guide slot 211 is used to place the optical fiber that is connected to the MT ferrule 3. The first claw 12, the second claw 13, and the MT ferrule 3 are located in the placement slot 212, and the reference block 11 is located in the limiting slot 213.

[0039] In this embodiment, the cable guide slot 211 is used to place the optical fiber that mates with the MT ferrule 3. Therefore, the cable guide slot 211 requires minimal space. The cross-sectional areas of the first claw 12, the second claw 13, and the MT ferrule 3 are smaller than the cross-sectional area of ​​the reference block 11. Therefore, the lateral width of the limiting slot 213 is greater than the lateral width of the placement slot 212. The lateral width is the slot width perpendicular to the optical signal transmission direction. However, since the lateral widths of the first claw 12, the second claw 13, and the MT ferrule 3 are greater than the lateral width of the reference block 11, the width of the placement slot 212 is greater than the width of the limiting slot 213. The width is the dimension on the horizontal plane parallel to the optical signal transmission direction. The placement slot 212 and the limiting slot 213 are used to limit the positioning of the adapter 1 with the MT ferrule 3 inserted.

[0040] Furthermore, in this embodiment, since the other end of the adapter 1 needs to be connected to the external device and the optical port 25, a corresponding structure is required to limit the external device. Therefore, this embodiment involves the following design.

[0041] like Figures 8-10 As shown, a positioning clamp 5 is provided on the second side 112 of the reference block 11; the periphery of the reference block 11 protrudes relative to the periphery of the positioning clamp 5; the size of the limiting groove 213 is adapted to the size of the reference block 11, and the periphery of the reference block 11 is located in the limiting groove 213.

[0042] In this embodiment, the positioning clamp 5 is arranged around the assembly port 14. The external device enters the positioning clamp 5 and docks with the MT insert 3 in the assembly port 14. The positioning clamp 5 is used to limit the peripheral movement of the external device. Both sides of the positioning clamp 5 are provided with buckles for cooperating with the external device to fix the external device.

[0043] like Figure 10As shown, the reference block 11 is stepped and protrudes relative to the clamping fixture 5. At the same time, the reference block 11 is also stepped and protrudes relative to the first claw 12 and the second claw 13. The reference block 11 is limited by the size-adapted limiting groove 213 to realize the limiting of the adapter 1. The reference block and the limiting groove 213 effectively isolate the two sides of the first side and the second side, effectively preventing the contamination dust on the second side from entering the first side. However, the disadvantage is that the reference block 11 will occupy more space inside the tube shell 2.

[0044] Furthermore, this embodiment also provides an alternative design for the reference block 11 and the positioning fixture 5 compared to the above structure.

[0045] like Figures 11-13 As shown, a positioning clamp 5 is provided on the second side 112 of the reference block 11; the periphery of the reference block 11 is aligned with the periphery of the positioning clamp 5, and one or more fixing grooves 51 are provided on the periphery of the positioning clamp 5; the limiting groove 213 extends toward the optical port 25 of the optical module housing, and one or more fixing bosses 214 are provided in the limiting groove 213, and the fixing bosses 214 are located in the fixing grooves 51.

[0046] like Figure 11 As shown, the reference block 11 extends directly to the periphery of the positioning clamp 5, and the step height difference between the reference block 11 and the positioning clamp 5 is relatively small. The adapter 1 is limited by the cooperation between the fixed boss 214 and the fixed groove 51. In this embodiment, four fixed grooves 51 can be provided on the periphery of the positioning clamp 5. The four fixed grooves 51 are arranged around the periphery of the positioning clamp 5. The corresponding positions on the limiting groove 213 are also provided with four fixed bosses 214 to correspond to the four fixed grooves 51. The advantage of the above design is that the reference block 11 does not need to be protruded with a large size and does not need to occupy a large amount of space inside the tube shell 2. However, the isolation effect of the reference block 11 between the first side and the second side is relatively weak, and it is difficult to effectively isolate the dust on both sides.

[0047] Furthermore, conventional optical modules come in two types: dual-port and single-port. For dual-port optical modules, two adapters 1 with MT ferrules 3 need to be installed inside the housing 2, and the interfaces of the MT ferrules 3 in both adapters 1 face the optical port 25. Therefore, this embodiment involves the following design: like Figure 14 and Figure 15 As shown, the tube shell 2 is provided with a plurality of receiving grooves 21 arranged side by side, and the outer side of the first claw 12 and the outer side of the second claw 13 are both in contact with the inner side of the receiving groove 21.

[0048] In this embodiment, since the dual-port optical module has two adapters 1, considering the size limitations of the optical module in the vertical direction, it is not advisable to stack the two adapters 1. However, if the two adapters 1 are arranged side by side in the housing 2, since the adapters 1 are laid flat, Figure 14 From a visual perspective, the length and width of the base surface have the largest area. If the two adapters 1 are placed flat inside the casing 2, the horizontal space occupied by the two adapters 1 would be too large to meet the size requirements of the casing 2. Therefore, in this embodiment, the adapters 1 are placed on their sides. Figure 14 From the perspective of the long and tall surface as the bottom surface, the horizontal area occupied by the two adapters 1 placed side by side is relatively smaller. Therefore, the two receiving slots 21 in the shell 2 are placed side by side and the receiving slots 21 are designed to be adapted to the side-placed adapters 1. The two inner sides of the receiving slots 21 abut against the outer side of the first claw 12 and the outer side of the second claw 13, respectively.

[0049] Furthermore, for a single-port optical module, an adapter 1 needs to be installed inside the housing 2. The interface of the MT ferrule 3 in the corresponding adapter 1 faces the direction of the optical port 25. In this case, since the size of a single adapter 1 is limited, it usually does not put too much pressure on the size of the housing 2. Therefore, this embodiment involves the following design.

[0050] like Figure 16 As shown, a receiving groove 21 is provided in the tube shell 2, and the outer side of the second claw 13 is in contact with the bottom surface of the receiving groove 21.

[0051] In this embodiment, when an adapter 1 is provided in the single-port optical module, the area occupied by a single adapter 1 in the horizontal direction when placed flat will not exceed the size limit of the housing 2. Based on this, in order to minimize the size occupied by the adapter 1 in the vertical direction, the adapter 1 is placed flat in the housing 2, that is, the adapter 1 is placed flat in the housing 2. Figure 14 Using the length and width as the bottom surface from the perspective, the height of adapter 1 is relatively small, so it occupies the smallest size in the vertical direction. The receiving groove 21 is designed to fit the flat adapter 1. The outer side of the second claw 13 is in contact with the lower end surface of the receiving groove 21, and the outer side wall of the first claw 12 is in contact with the upper end surface of the receiving groove 21.

[0052] Example 3: This embodiment, based on the above embodiments, provides a practical application scenario in which: one of the core components of optical fiber communication is the conversion of photoelectric signals. Optical fiber communication uses optical signals carrying information to transmit in optical fibers / waveguides, utilizing the passive transmission characteristics of light in optical fibers to achieve low-cost, low-loss information transmission. However, information processing devices such as computers use electrical signals, which necessitates the mutual conversion between electrical and optical signals during signal transmission.

[0053] In the field of fiber optic communication technology, optical modules realize the aforementioned photoelectric conversion function, and the mutual conversion between optical signals and electrical signals is the core function of optical modules. Optical modules achieve electrical connection with external host computers through gold fingers on the circuit board. The main electrical connections include power supply, I2C signals, data transmission signals, and grounding. The gold finger-based electrical connection method has become the standard method in the optical module industry. Based on this, the circuit board is an essential technical feature in most optical modules.

[0054] Figure 17 This is a schematic diagram illustrating the connection relationship of optical communication terminals, using a hybrid mode optical modem as an example.
