Description

Optical fiber coiling device and winding method thereof

The invention relates to a coiling device for an optical fiber and a winding method thereof, and particularly relates to a device and a method for coiling and storing a pigtail, an optical fiber and a fiber jumper in a communication device. Background technique

In the field of communication, the fiber, fiber, and fiber jumper of various communication devices or connection devices and optical cables are generally referred to as optical fibers. Modern communication rooms are filled with communication equipment, and the number of optical fibers connected to them is large. One end of the optical fiber is connected to a communication device such as a transmission device or a switch, and the other end is connected to an optical distribution device (ODF). The fiber is uniformly tuned in the optical distribution equipment to connect the different devices to form the desired communication network. A large-capacity optical distribution device can access more than 1000 optical fibers.

When the fiber is routed, the length of the fiber is 1 to 10 meters longer or more, and the excess fiber is usually placed and stored in a device that is connected to the fiber or through which the fiber passes. Disc fiber, the process of coiling excess fiber. The device used to store excess fiber is a disk device. As shown in Fig. 13, the large-span fiber-optic device usually consists of two sets of symmetrically distributed coiled cylinders 10. The two sets of coiled cylinders 10 have a large distance between them, and can be stored in a circle for about 1 to 4 meters. The length of the fiber, the vast majority of the fiber 9 is stored in the large-span fiber-optic device. Small-span fiber-optic devices are usually circular, single-cylinders 11, which can hold only a small number of fixed-length fibers 9 in a single coil. At present, optical distribution equipment generally uses a large-span fiber-optic device to cooperate with a small-span fiber device to store excess optical fibers.

In the maintenance of the communication network, it is often necessary to adjust the connection relationship of the optical fibers, that is, to schedule. When operating, first remove the end plug of the adjusted fiber from the adapter, then remove the part of the fiber wrapped around the fiber device, re-route, coil, and then plug the fiber end plug into the new adapter. in. It has the following disadvantages:

1. Fiber accumulation, scheduling is difficult. Due to the limitations of the wiring equipment space, the large-span disk replacement page "Article 26" The number of devices is limited, and a large number of optical fibers are stacked on the same set of fiber-optic devices, which are mutually squeezed, and the fiber scheduling is extremely inconvenient. After a large number of fibers are scheduled at one time, or after multiple operations of scheduling fibers, the kinking phenomenon between the fibers becomes very serious, which may result in the inability to perform new scheduling operations, and the optical wiring device loses the most basic configuration. Line function.

2. Scheduling time signal interruption time is very long. Since the plug of one end of the fiber is first unplugged from the adapter during scheduling, and then many operations can be performed, the plug is plugged in at the last moment of scheduling, so the signal in the optical fiber is interrupted during the entire scheduling process.

3. The scrapped fiber cannot be removed. After the fiber is repeatedly scheduled, the fiber will be kinked together. When the fiber is twisted and can not be separated, the new fiber can only be used to replace the scheduling fiber. The scrap fiber can not be removed, and it can only be left in the wiring device, which not only takes up space, but also takes up space. And will cause hidden communication

4. Accurate coiling is not possible, leaving excess fiber. Since the length of the disk of the small span fiber device is a fixed value, the excess fiber smaller than the length can only be randomly placed in the wiring device.

5. Fiber distortion, increase construction difficulty and reduce construction speed. The existing fiber-optic device generates torque in the fiber during the fiber-optic process, which causes the pigtail to rotate around its axis, which easily causes the fiber itself and the other fibers to be entangled, which increases the construction difficulty and affects the construction speed.

Or a circular, elliptical shape composed of a plurality of column combinations, see Figures 3 and 5.

The upright or curved plate constituting the fiber-optic shaft 3 may further comprise a disk column 6 on the side of the fiber-optic channel 8, see Figures 2, 3, 5. The fiber column 6 includes a fiber side 4 of the wound fiber 9 and may also include a limit side 5 on the side of the fiber channel 8. During operation, the fiber-optic inlet 9 of the disk to be stored is embedded in the fiber-optic channel 8 to rotate the fiber-optic shaft 3, and under the action of the limiting side 5, the fiber 9 is wound around the fiber along the fiber-side side 4 On the shaft 3.

Referring again to FIG. 6, an embodiment of the fiber winding method according to the present invention includes the following steps:

1). Inlaid fiber: After the optical fiber 9 enters the communication device, the central portion of the optical fiber 9 that needs to be stored is embedded in the fiber-optic channel 8 of the disk fiber column 6;

2). The central section of the optical fiber 9 is formed with a smooth curve of an odd number of inflection points 1 2 in the fiber insertion channel 8;

4). Disc: Rotating the disc column 6, so that the fiber 9 on both sides of the center section is wound on the disc column 6 along the smooth curve in the same direction.

In the case of fiber insertion, in order to make the optical fiber 9 coiled evenly and completely, generally, the end of the optical fiber 9 is connected to the adapter, and then the central segment is selected for the fiber. The number of inflection points of the curve in the inlaid channel 8 is optimal with one inflection point, and the implementation is simple, and the signal attenuation is small. Number of inflection points The amount can also be three or more, but the total number of inflection points must be an odd number. The formation of a smooth curve in the center section of the fiber 9 in the fiber channel 8 means that the connection between the curves is a smooth transition. The fiber is obtained by winding the optical fiber 9 or the clockwise or counterclockwise disk on the fiber column 6. In practical applications, it can be selected as needed. The plane of the smooth curve with an odd number of inflection points in the fiber channel 8 may be parallel to the cross section of the fiber column 6, as shown in Fig. 7, or may form an angle with the cross section of the fiber column 6, see Fig. 8.

The fiber-optic mode can be divided into three types: The first method is that the fiber 9 is only spirally stacked along the fiber column 6 to form a single layer arrangement along the axial direction, which mainly occupies the radial space of the disk fiber column 6, as shown in FIG. In the second mode, the optical fibers 9 are only spirally wound along the axial direction of the fiber column 6 to form a single layer arrangement in the radial direction, which mainly occupies the axial space of the fiber column 6 . See Figure 1 0. In the third mode, the optical fiber 9 is wound both in the axial direction of the fiber column 6 and in the radial direction of the fiber column 6. That is, the optical fiber 9 is formed in two or more layers in the axial direction and the radial direction of the fiber column .6, and the space to be occupied can be selected as needed. An embodiment using the fiber-optic mode 3 is shown in Fig. 1 1. In this manner, the optical fibers on both sides of the central segment can be wound in two layers in a radial direction, as shown in Fig. 12.

During maintenance, if the fiber 9 needs to be scheduled, the disk string 6 is rotated in the reverse coil direction, and the fiber 9 wound on the disk column 6 is completely released. At this time, the connection end of the fiber 9 can be removed from the current adapter. Unplug it and plug it into the desired adapter. The released fiber 9 is then re-wound onto the disk column 6 in accordance with the winding step. Since all of the optical fibers 9 are stored on the respective fiber strings 6, the optical fibers are independent of each other and do not affect each other.
