It features a compact size, a wide operating wavelength range, high reliability, and excellent optical splitting uniformity. This splitter is particularly suitable for connecting central offices and terminal devices in passive optical networks and for splitting optical signals. Currently, the market primarily offers 1×N and 2×N types.

[0003] The optical fiber of the bare fiber optical splitter is composed of a hard protective cover wrapped around the outside of the optical fiber, and is connected by plugging. Because the outlet of the bare fiber optical splitter is preset with multiple groups of optical fibers for plugging, and during the plugging process, there will be a large number of groups of optical fibers, and it is not necessary to plug all of them. At this time, the optical fiber plugging parts exposed to the air will be in contact with dust in the air for a long time, causing failure during subsequent plugging. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] The following is combined with Figure 1-4 The embodiments of the present application are described in further detail.

[0027] Example 1

[0028] See also Figure 1-Figure 4 , this embodiment provides a technical solution: a bare fiber optical splitter, comprising: an optical splitter body 1, a frame 2, a driving mechanism 3, a first optical fiber 4 and a second optical fiber 5;

[0029] The optical splitter body 1 is based on the physical properties of the optical waveguide. When a single-mode optical fiber transmits an optical signal, the energy of the light is not completely concentrated in the core and propagates. A small amount is propagated through the cladding close to the core. Therefore, when the cores of the two optical fibers are close enough, the mode field of the light transmitted in one optical fiber can enter the other optical fiber, thereby realizing the redistribution of the optical signal in the two optical fibers. The above is the existing technology and will not be repeated below. The frame 2 is set at the bottom of the optical splitter body 1. The frame 2 is connected by bonding. The cavity opened inside the frame 2 can provide the placement of the internal structure, and the bottom of the frame 2 is provided with a strip through hole, which can provide the internal structure with sliding displacement, and the side of the frame 2 is provided with a rectangular through hole, which can provide the internal structure with sliding displacement. The pushing mechanism 3 is set inside the frame 2, and the pushing mechanism 3 can provide a stable driving force for the internal structure of the frame 2 to move.

[0030] The pushing mechanism 3 includes a slider 301 slidably connected to the inside of the bar-shaped through-hole of the frame 2, and the slider 301 can be stably moved inside the bar-shaped through-hole of the frame 2, and the "U"-shaped block 302 bonded to one end of the slider 301, and the "U"-shaped block 302 can be connected with the slider 301, thereby achieving stable movement of the structure, and a No. 1 limit block 303 bonded to one end of the "U"-shaped block 302, and the No. 1 limit block 303 can limit the structure at one end, and a No. 2 limit block 304 bonded to the other end of the "U"-shaped block 302, and the No. 2 limit block 304 can cooperate with the No. 1 limit block 303 to limit the inner structure, and a shift block 305 bonded to the other end of the slider 301, and the shift block 305 can be provided for people to hold, thereby driving the structure connected to the outer wall to move synchronously, and the shift block 305 is arranged on the outside of the frame 2, which can provide convenience when people hold it.

[0031] The optical fiber No. 1 4 is connected to the outlet of the optical splitter main body 1, and the optical fiber No. 1 4 can be plugged into the device. The optical fiber No. 1 4 is arranged inside the No. 1 limit block 303 and the No. 2 limit block 304, and can drive the No. 1 optical fiber 4 to move synchronously during the movement of the No. 1 limit block 303 and the No. 2 limit block 304. The optical fiber No. 2 5 is connected to the inlet of the optical splitter main body 1, and the optical fiber No. 2 5 can be plugged into the device.

[0032] The No. 2 optical fiber 5 is plugged into the device to transmit the signal to the optical splitter body 1. When the optical splitter body 1 needs to be transmitted to another group of devices through the No. 1 optical fiber 4, the dial block 305 is toggled. At this time, the dial block 305 will drive the slider 301 connected to the outer wall to move inside the strip-shaped through hole of the frame 2. At this time, the slider 301 will drive the "U"-shaped block 302 to move. When the "U"-shaped block 302 moves, because the No. 1 optical fiber 4 is limited by the No. 1 limit block 303 and the No. 2 limit block 304 inside the "U"-shaped block 302, the No. 1 optical fiber 4 can be pushed out of the frame 2 during the movement, thereby quickly realizing the connection with another group of devices.

[0033] Example 2

[0034] See also Figure 1-Figure 4 , this embodiment provides a technical solution: a bare fiber optical splitter, comprising: a first rack 306, a second rack 307, a hinge 308 and a baffle 309;

[0035] The No. 1 rack 306 bonded to the shift block 305 can mesh with the structures to quickly achieve fixation. The No. 2 rack 307 bonded to both sides of the outer wall of the strip-shaped through hole of the frame 2 can mesh with the No. 1 rack 306 to quickly position the No. 1 rack 306. The No. 2 rack 307 meshes with the No. 1 rack 306. After the No. 1 rack 306 moves to the specified position, the positioning and fixing work can be quickly achieved.

[0036] A hinge 308 is fixed on the outer wall of the rectangular through hole of the frame 2, and the hinge 308 is connected to the outer wall of the frame 2 by bolts. A baffle 309 is fixed at the other end of the hinge 308, and the baffle 309 is connected to the hinge 308 by bolts. The baffle 309 is set inside the rectangular through hole of the frame 2, and the baffle 309 can be rotated to determine whether to block the rectangular through hole of the frame 2.

[0037] During the movement of the shift block 305, the No. 1 rack 306 on the outer wall can engage with the No. 2 rack 307 on the outer wall of the frame 2, thereby providing a quick snap-in fixation to avoid entanglement between the No. 1 optical fibers 4. The baffle 309 in the rectangular through hole of the frame 2 can be rotated open by the hinge 308.

[0038] The implementation principle of a bare fiber optical splitter of the present application is:

[0039] First, the second optical fiber 5 is plugged into the device to transmit the signal to the optical splitter body 1 .

[0040] Secondly, when it is necessary to transport the optical splitter body 1 to another group of equipment through the optical fiber No. 1 4, the baffle 309 in the rectangular through hole of the frame 2 can be rotated and opened by the hinge 308, and the dial block 305 is moved. At this time, the dial block 305 will drive the slider 301 connected to the outer wall to move inside the strip through hole of the frame 2, and the slider 301 will drive the "U"-shaped block 302 to move. When the "U"-shaped block 302 moves, because the optical fiber No. 1 4 is limited by the No. 1 limit block 303 and the No. 2 limit block 304 inside the "U"-shaped block 302, the optical fiber No. 1 4 can be pushed out of the frame 2 during the movement, thereby quickly realizing the connection with another group of equipment.

[0041] Finally, during the movement of the shift block 305 , the first rack 306 on the outer wall can engage with the second rack 307 on the outer wall of the frame 2 , thereby providing a quick engagement and fixation.

[0042] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
