[0048] In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Embodiment 1:

[0050] Embodiment 1 of the present utility model provides an optical fiber disk, such as Figure 1 It includes: a chassis 1, a first optical fiber channel 2, a single fiber lead slot 4, a sinking slot 5 and a fiber lead channel 6, wherein:

[0051] The first optical fiber channel 2 is arranged on the chassis 1; the first optical fiber channel 2 includes a plurality of optical fiber grooves, and the optical fiber groove in the innermost circle is extended to be provided with the single fiber lead groove 4.

[0052] Each circle of optical fiber grooves in the first optical fiber channel 2 includes a plurality of arc grooves connected in sequence; the first optical fiber channel 2 includes a second arc region 22, and the arc center of the arc groove in the second arc region 22 is located outside the first optical fiber channel 2; the innermost circle of arc grooves in the second arc region 22 is extended with the single fiber lead groove 4.

[0053] In this embodiment, the first optical fiber channel 2 is used for winding the optical fiber, and one end of the optical fiber starts to be wound from the optical fiber groove at the inner circle position of the first optical fiber channel 2; the arc groove is a section of optical fiber groove that is curved in an arc shape; each circle of optical fiber grooves in the first optical fiber channel 2 is formed by a plurality of arc grooves connected in sequence, and the arc directions between two adjacent arc grooves are opposite, and the two adjacent arc grooves are tangentially connected; wherein the arc grooves are selected to have a suitable arc radius to ensure the high-order mode loss intensity and beam quality of the optical fiber and improve the transverse mode instability (TMI) threshold, and the arc radius of the arc groove needs to be determined according to the model of the optical fiber. The arc center of the arc groove in the second arc area 22 is located outside the first optical fiber channel 2, which means that the arc groove in the second arc area 22 is curved toward the inside of the first optical fiber channel 2. In this embodiment, the arc radius of each arc groove on the first optical fiber channel 2 can be 5cm-7.8cm.

[0054] In this embodiment, considering the heat dissipation effect of the optical fiber when working in the optical fiber tray, the chassis 1 can be made of aluminum material to improve the heat dissipation efficiency of the optical fiber tray.

[0055] In this embodiment, a certain length of optical fiber lead-out needs to be reserved at the inner circle position of the first optical fiber channel 2 for connection with other optical devices to realize the winding arrangement and normal operation of the optical fiber. Since the arc groove at the inner circle position of the second arc region 22 in this embodiment is bent toward the inner circle of the first optical fiber channel 2, in the inner circle of the first optical fiber channel 2, the peripheral side of the arc groove of the second arc region 22 has a corresponding space to set a groove for leading out the optical fiber in the arc groove.

[0056] In this embodiment, the inner circle of the first optical fiber channel 2 refers to a middle area surrounded by the optical fiber grooves at the inner circle position of the first optical fiber channel 2 where no optical fiber grooves are provided.

[0057] like Figure 2 and Figure 3 As shown, the arc-shaped groove at the inner circle position of the second arc-shaped area 22 is extended with the single fiber leading groove 4, and one end of the single fiber leading groove 4 is tangent to the arc-shaped groove at the inner circle position of the second arc-shaped area 22.

[0058] like Figure 1-Figure 3As shown, since the first optical fiber channel 2 in this embodiment is an optical fiber groove arranged in multiple circles, if the corresponding structural design is not made, the optical fiber led out of the single fiber lead groove 4 needs to be extended out of the chassis 1 along the direction of the single fiber lead groove 4 to connect with other optical devices. This process will cause the led optical fiber to cover the upper ends of other optical fibers in the first optical fiber channel 2; since the optical fiber has a heating problem when it is actually working, it will affect the performance of the optical fiber itself. If the optical fiber leading out of the single fiber lead groove 4 is directly arranged above other optical fibers, the heat dissipation of this part of the optical fiber will be suppressed, thereby affecting the performance of the optical fiber. Therefore, this embodiment provides an optical fiber tray with a corresponding structural design to prevent the optical fiber led out of the single fiber lead groove 4 from covering the upper ends of other optical fibers on the lead-out path. The corresponding structural design is:

[0059] like Figure 1-Figure 3 As shown, the sinking groove 5 is arranged on the chassis 1, and the sinking groove 5 is connected to the fiber introduction single groove 4. The side of the sinking groove 5 facing the fiber introduction single groove 4 is a guiding slope 51, and the guiding slope 51 extends to the bottom of the sinking groove 5; a fiber introduction channel 6 is arranged on the inner side surface of the sinking groove 5 on the side facing away from the fiber introduction single groove 4, and the fiber introduction channel 6 leads to the outer side surface of the chassis 1.

[0060] The single fiber lead-in groove 4 is used to lead the optical fiber out from the arc groove at the inner circle position of the second arc region 22 , and to lead the optical fiber out from the outer side surface of the chassis 1 through the fiber lead-in channel 6 .

[0061] like Figure 2 and Figure 3 As shown, the optical fiber in the single fiber lead slot 4 is led to a horizontal height position lower than the fiber slot through the guiding slope 51, and extends out of the chassis 1 through the fiber lead channel 6. Since the horizontal height of the fiber lead channel 6 is lower than the horizontal height of the fiber slot, the optical fiber in the fiber lead channel 6 will not contact the optical fiber in the fiber slot, thereby avoiding the lead-out optical fiber interfering with the heat dissipation of the optical fiber in the fiber slot, thereby improving the heat dissipation performance of the overall optical fiber in the fiber tray.

[0062] Furthermore, in order to be compatible with more optical fibers of different lengths, the optical fiber tray in this embodiment, based on the above structural design, also involves the following designs:

[0063] like Figure 4 As shown, the optical fiber disk also includes a second optical fiber channel 3, which is arranged on the chassis 1; the second optical fiber channel 3 is an optical fiber groove arranged in multiple circles, and the second optical fiber channel 3 is located at the periphery of the first optical fiber channel 2, and the optical fiber groove of the second optical fiber channel 3 at the inner circle position is connected to the optical fiber groove of the first optical fiber channel 2 at the outer circle position.

[0064] It should be noted that the outer circle position in this embodiment refers to the position of the optical fiber groove of the outermost circle of the first optical fiber channel 2 or the second optical fiber channel 3, and the inner circle position refers to the position of the optical fiber groove of the innermost circle of the first optical fiber channel 2 or the second optical fiber channel 3.

[0065] like Figure 4 As shown, in this embodiment, the second optical fiber channel 3 and the first optical fiber channel 2 are both optical fiber grooves arranged on the chassis 1, and the second optical fiber channel 3 is connected to the first optical fiber channel 2 for winding the same optical fiber. It should be noted that in this embodiment, the length of the optical fiber is greater than the total length of the optical fiber groove of the first optical fiber channel 2, and one end of the optical fiber is arranged starting from the optical fiber groove at the inner circle position of the first optical fiber channel 2. When all the optical fiber grooves of the first optical fiber channel 2 are fully arranged, the optical fiber groove at the inner circle position of the second optical fiber channel 3 is continued to be arranged. When the optical fiber is basically all arranged, a certain length is reserved for outputting the fiber from the second optical fiber channel 3 and connected to other optical devices to realize the winding arrangement and normal operation of the optical fiber.

[0066] After the optical fiber fills the optical fiber groove in the first optical fiber channel 2, it continues to be coiled in the second optical fiber channel 3, and finally the optical fiber is taken out at a certain circle layer of the second optical fiber channel 3. Since the optical fiber outlet position needs to be fused, the fusion point position needs to be kept straight, so it cannot be led out at the arc groove position, otherwise there will be stress at the bending position, resulting in reduced reliability of the fusion point position. Therefore, this embodiment needs to ensure that the optical fiber can be taken out at the straight optical fiber groove position, so this embodiment also involves the following designs:

[0067] like Figure 4 As shown, each circle of optical fiber grooves in the second optical fiber channel 3 includes at least one straight groove and a plurality of arc grooves connected in sequence; wherein the arc grooves are used to improve the performance of the optical fibers arranged therein, and the straight grooves are used to arrange the optical fibers or provide optical fiber outlets.

[0068] In this embodiment, the linear groove is a straight section of optical fiber groove; the arc groove is used to improve the high-order mode loss, beam quality and TMI threshold of the optical fiber arranged therein; the linear groove is used to set the optical fiber or provide the optical fiber for fiber output; since the second optical fiber channel 3 includes multiple circles of optical fiber grooves arranged around, each circle of optical fiber grooves and each circle of linear grooves can be used for fiber output; when the optical fiber length is relatively short, the optical fiber is output at the linear groove near the inner circle position of the second optical fiber channel 3; when the optical fiber length is relatively long, the optical fiber is output at the linear groove near the outer circle position of the second optical fiber channel 3; therefore, the optical fiber disc provided in this embodiment is compatible with optical fibers of different lengths. It should be noted that in this embodiment, the optical fiber can be bonded to the optical fiber groove at the corresponding position by glue to achieve the fixation of the optical fiber in the optical fiber groove.

[0069] In this embodiment, the optical fiber disc can be used to set a 20 / 400 type active optical fiber, that is, an active optical fiber with a 20um core and a 400um cladding, and a 14 / 250 type active optical fiber, that is, an active optical fiber with a 14um core and a 250um cladding.

[0070] Taking the 20 / 400 model active optical fiber as an example, when the optical fiber disk is used to set the 20 / 400 model active optical fiber, the arc radius of each arc groove in the first optical fiber channel 2 can be 5cm-7.8cm, and the total length of the optical fiber grooves in the first optical fiber channel 2 can be 20m. When the 20 / 400 model active optical fiber is set in an arc groove with an arc radius of 5cm-7.8cm, the high-order mode loss of the 20 / 400 model active optical fiber is relatively strong. As the arc radius of the arc groove continues to increase, the high-order mode loss of the 20 / 400 model active optical fiber is almost negligible.

[0071] In this embodiment, the maximum circumference of the second optical fiber channel 3 can be 36m, and finally the area size of the entire optical fiber disk does not exceed 35cm*19cm.

[0072] Based on the above description, this embodiment provides a preferred structural design of the first optical fiber channel 2 as follows:

[0073] like Figure 5 As shown, the first optical fiber channel 2 also includes a first arc region 21, a third arc region 23 and a fourth arc region 24, and the first arc region 21, the second arc region 22, the third arc region 23 and the fourth arc region 24 are connected end to end in sequence; the first arc region 21, the second arc region 22, the third arc region 23 and the fourth arc region 24 all include arc grooves at corresponding positions of all circles in the first optical fiber channel 2.

[0074] In this embodiment, the first arc region 21 is connected to the second arc region 22 , the second arc region 22 is connected to the third arc region 23 , the third arc region 23 is connected to the fourth arc region 24 , and the fourth arc region 24 is connected to the first arc region 21 .

[0075] like Figure 5 As shown, the first arc-shaped area 21 and the third arc-shaped area 23 are arranged opposite to each other, and the arc centers of the arc-shaped grooves in the first arc-shaped area 21 and the arc centers of the arc-shaped grooves in the third arc-shaped area 23 are both located inside the first optical fiber channel 2 .

[0076] In this embodiment, the arc grooves in the first arc region 21 and the third arc region 23 are both bent toward the outside of the first optical fiber channel 2. At this time, the arc centers of the arc grooves in the first arc region 21 and the arc centers of the arc grooves in the third arc region 23 are both located inside the first optical fiber channel 2; and the arc radii of the arc grooves in the first arc region 21 and the third arc region 23 can correspond to each other.

[0077] like Figure 5 As shown, the second arc-shaped area 22 and the fourth arc-shaped area 24 are arranged opposite to each other, and the arc centers of the arc-shaped grooves in the second arc-shaped area 22 and the arc centers of the arc-shaped grooves in the fourth arc-shaped area 24 are both located outside the first optical fiber channel 2 .

[0078] In this embodiment, the arc grooves in the second arc region 22 and the fourth arc region 24 are both bent toward the inside of the first optical fiber channel 2. At this time, the arc centers of the arc grooves in the second arc region 22 and the arc centers of the arc grooves in the fourth arc region 24 are both located outside the first optical fiber channel 2.

[0079] like Figure 5 As shown, the second optical fiber channel 3 includes a fifth arc region 31, a first straight region 32, a sixth arc region 33 and a second straight region 34 which are connected end to end in sequence; the fifth arc region 31 and the sixth arc region 33 both include arc grooves at corresponding positions of all circles in the second optical fiber channel 3, and the first straight region 32 and the second straight region 34 both include straight grooves at corresponding positions of all circles in the second optical fiber channel 3.

[0080] The fifth arc region 31 , the first straight region 32 , the sixth arc region 33 and the second straight region 34 are all different parts of the second optical fiber channel 3 , and the fifth arc region 31 , the first straight region 32 , the sixth arc region 33 and the second straight region 34 all include a portion of the optical fiber groove in the second optical fiber channel 3 .

[0081] like Figure 5 As shown, the fifth arc-shaped area 31 and the sixth arc-shaped area 33 are opposite to each other, and the arc centers of the arc-shaped grooves in the fifth arc-shaped area 31 and the arc centers of the arc-shaped grooves in the sixth arc-shaped area 33 are both located inside the second optical fiber channel 3 .

[0082] In this embodiment, the arc grooves in the fifth arc region 31 and the sixth arc region 33 are both bent toward the outside of the second optical fiber channel 3. At this time, the arc center of the arc groove in the fifth arc region 31 and the arc center of the arc groove in the sixth arc region 33 are both located inside the second optical fiber channel 3.

[0083] like Figure 5As shown, the first straight area 32 and the second straight area 34 are located opposite to each other, and the first straight area 32 and the second straight area 34 both contain the straight grooves.

[0084] It is worth mentioning that, in this embodiment, the fifth arc-shaped area 31 can be arranged on the periphery of the first arc-shaped area 21, the sixth arc-shaped area 33 can be arranged on the periphery of the third arc-shaped area 23, the first straight line area 32 can be arranged on the periphery of the second arc-shaped area 22, and the second straight line area 34 can be arranged on the periphery of the fourth arc-shaped area 24.

[0086] The transition position between the second optical fiber channel 3 and the first optical fiber channel 2 may be between the fifth arc-shaped area 31 and the first arc-shaped area 21 or between the sixth arc-shaped area 33 and the third arc-shaped area 23 .

[0087] Through the above structural design, the second optical fiber channel 3 and the first optical fiber channel 2 are arranged more compactly, and the occupied area on the chassis 1 is smaller.

[0088] Accordingly, in order to further be compatible with optical fibers of various lengths, the present embodiment can adjust the coil layer of the optical fiber set in the optical fiber groove by means of fiber jumper, so as to be compatible with relatively shorter optical fibers. Therefore, the present embodiment also involves the following designs:

[0089] In this embodiment, the length of the first 15 turns of the first optical fiber channel 2 is 10.5 m. According to the heat conduction equation of the optical fiber, 95% of the heat of the optical fiber is concentrated in the first 10 m of the optical fiber, so fiber jumper can only be performed after the 15th turn.

[0090] like Figure 6 As shown, a first fiber jump slot 25 is provided on the first arc-shaped area 21 , and the first fiber jump slot 25 is connected with at least two circles of arc-shaped slots, and the first fiber jump slot 25 is located at the 20th to 24th circles of optical fiber slots.

[0091] like Figure 6 As shown, a second fiber jumper slot 26 is provided on the third arc-shaped area 23 , and the second fiber jumper slot 26 is connected with at least two circles of arc-shaped slots, and the second fiber jumper slot 26 is located at the 15th to 19th circles of optical fiber slots.

[0092] like Figure 6 As shown, the first straight region 32 is provided with a third fiber jump slot 35, and the third fiber jump slot 35 is located at the 31st to 35th straight grooves. Alternatively, the second straight region 34 is provided with a third fiber jump slot 35, and the third fiber jump slot 35 is located at the 31st to 35th straight grooves.

[0093] The present embodiment provides a preferred design of a first fiber jump slot 25, a second fiber jump slot 26 and a third fiber jump slot 35, wherein the first fiber jump slot 25, the second fiber jump slot 26 and the third fiber jump slot 35 all serve as fiber jump slots, and optical fibers at different circle positions can be jumped through the fiber jump slots to achieve position adjustment of the optical fibers; specifically, any optical fiber slot at one end of the fiber jump slot can be arranged and connected with any optical fiber slot at the other end.

[0094] Among them, the first fiber jumping groove 25 can be located between the 20th circle of arc grooves and the 24th circle of arc grooves in the first arc area 21, the second fiber jumping groove 26 can be located between the 15th circle of arc grooves and the 19th circle of arc grooves in the third arc area 23, and the first fiber jumping groove 25 can be located between the 31st circle of straight grooves and the 35th circle of straight grooves in the first straight area 32 or the second straight area 34.

[0095] like Figure 7-Figure 9 As shown, taking the second fiber jump slot 26 as an example, Figure 7 This is a schematic diagram of the fiber winding without fiber patching. Figure 8 This is a schematic diagram of the winding of the optical fiber when jumping one circle. Fig. 9 Schematic diagram of the winding of the optical fiber when it jumps two circles.

[0096] like Fig.10 As shown, when optical fibers of different lengths are arranged in the combined optical fiber tray provided in this embodiment, optical fibers of different lengths are jumpered in the first jumper slot 25 and the second jumper slot 26; Fig.10 The No. 1 slot in the table is the second fiber jump slot 26, and the No. 2 slot in the table is the first fiber jump slot 25; it should be noted that since the third fiber jump slot 35 is generally used for fine-tuning the fiber jump when the optical fiber finally emerges from the straight slot, the fine-tuning is generally caused by the length mismatch caused by the error when the optical fiber is processed and cut, so Fig.10 is not considered in the table for now.

[0097] In this embodiment, before the fusion splicing point is set at the fiber outlet position of the optical fiber, the optical fiber near the fiber outlet position usually needs to be fixed by adhesive tape, and the adhesive tape usually covers and fixes the optical fiber inside the optical fiber groove from the top of the optical fiber groove. However, since most of the optical fiber has been immersed in the optical fiber groove, it is difficult for the adhesive tape to contact and cover the optical fiber over a large area, resulting in limited bonding and fixing effect on the optical fiber. Therefore, this embodiment involves the following designs:

[0098] like Figure 6 As shown, the first straight area 32 is provided with a bonding and fixing groove 36. Alternatively, the second straight area 34 is provided with a bonding and fixing groove 36. Each circle of optical fiber grooves on the first straight area 32 or the second straight area 34 is removed at the position of the bonding and fixing groove 36, and the bonding and fixing groove 36 is used for adhesive tape to fix the optical fiber in the bonding and fixing groove 36.

[0099] The optical fiber grooves at the positions of the bonding and fixing grooves 36 are all removed, so that optical fibers at different ring positions can also be jumped through the bonding and fixing grooves 36 to achieve position adjustment of the optical fibers in the second optical fiber channel 3 .

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
