In one embodiment, the connection jumper 13 has both the function of light transmission and the function of current transmission. In one embodiment, the connector 131 may be an optical fiber connector. In other embodiments, the connector 131 may also be an optoelectronic connector. Correspondingly, the cable may be an optical fiber, and the cable may also include both optical fibers and wires. For the connector 133 in the connection jumper provided by the present application, taking the optical fiber connector as an example, it is classified according to the different transmission media. There are other optical fiber connectors such as plastics as the transmission medium. According to the structure of the connector, the connectors can be divided into: FC, SC, ST, LC, D4, DIN, MU, MT and so on. In addition to the above-mentioned various forms of plug structures, the connectors for connecting jumpers and spare jumpers provided by the present application can also be miniaturized and customized bullet-type connectors.

The spare jumper includes a cable and two connectors (which are plugs matched with the adapter ports) , the two connectors are respectively connected at both ends of the cable. The spare jumper has the same structure as the connecting jumper. When the spare jumper is connected to the wiring panel, it becomes the connecting jumper. In one embodiment, the spare jumper can be an optical jumper, and its connector is an optical fiber connector. The number of jumper storage devices can be one or more, and the number of spare jumpers in the jumper storage device can be multiple. In the case of frequent update or replacement needs, a larger number of spare jumpers can be configured, or the number of jumper storage devices can be increased.

The specific meaning of "discarded" refers to a jumper that has been replaced in an optical path of a certain service. In one embodiment, after the discarded jumper is transported to the recycling box, it may only include one connector connected to one end of the cable, and the other connector is cut off during the process of recycling the jumper to facilitate the discarded jumper. Recycling of cables, for example, when the connector connecting the jumper is a common SC plug structure, after the jumper is removed from the wiring panel, it becomes a discarded jumper, in order to ensure the smoothness of the process of recycling the jumper , to prevent the connector at the end of the discarded jumper from interfering with other connecting jumpers during the process of recycling the jumper, which affects the recycling of the jumper. It is necessary to cut off one connector of the discarded jumper. In another embodiment, the discarded jumper may include a cable and two connectors connected to both ends of the cable, respectively, the two connectors are of smaller size models, such as custom bullet-type connectors, the size of For smaller connectors, the shell of the connector is designed with a sleek or pointed tip.

In this embodiment, the storage area is an area where the jumper storage device is installed. In other embodiments, the storage area in the optical fiber distribution equipment provided by the present application may be a window (interface) for the optical fiber distribution equipment to receive spare jumpers, and the optical fiber distribution equipment does not include a jumper storage device, and the jumper storage device is: A device independently arranged outside the optical fiber distribution equipment can transport (or load) the jumper storage device to the storage area of the optical fiber distribution equipment through an external device, that is, the jumper storage device can be introduced externally.

The insertion and extraction device can be understood as an automatic transmission and execution device provided with a gripper (or a manipulator, or a robot). The plugging device can move between the wiring area and the storage area, and/or between the wiring area and the recycling area. The plugging and unplugging device can perform plugging and unplugging operations in the wiring area, perform fiber fetching (that is, take out the spare jumper wire from the jumper storage device) in the storage area, and perform recycling in the recycling area. action. The plug-in device can take out the spare jumper from the jumper storage device, and insert the two connectors of the spare jumper into the corresponding first port and the second port respectively to realize the optical path; and/or pulling out the two connectors of the connection jumper from the corresponding first port and the second port respectively, and the pulled-out connection jumper is the discarded jumper, The plug-in device is used for transporting the discarded jumper wires to the jumper wire recovery device.

The traditional optical fiber distribution equipment includes two distribution panels (or two distribution areas on one panel), one of which is used to set connectors (or two distribution areas on one panel). Plug), each connector is connected to optical fibers (also known as pigtails), which can be understood as this patch panel is used to connect a large number of optical fibers, these optical fibers are multiplexed optical fibers, that is, a certain optical fiber needs to be used repeatedly to perform different services need. When a fiber needs to be used to connect an optical path, the fiber needs to be pulled out from one distribution panel by the robot arm, transported to another distribution panel, and inserted into the adapter of the other distribution panel on the port. When a certain optical path needs to be disconnected, the corresponding optical fiber is to be retracted, that is, its connector is pulled out of the adapter port and returned to its original position. Under this structure, the optical fiber distribution equipment needs a large space to store this part of the optical fiber, which is not only expensive but also bulky. Moreover, each optical fiber needs to be managed in an orderly manner. It is in a straight state in the storage space, and the optical fiber is stretched for a long time. During the process of plugging and retracting, pulling the optical fiber back and forth will lead to a decrease in the service life of the optical fiber, which may cause signal damage to optical communication services. Interruption or adverse risk.

The optical fiber wiring equipment provided in this application is a consumable type wiring equipment. The spare jumper is taken out from the jumper storage device through the plug-in module. The spare jumper is used as a disposable consumable material. Connected between the first port and the second port to realize the optical path of the corresponding service port. Since the spare jumper is a disposable consumable material, the spare jumper is stored in the jumper storage device before being connected to the first port and the second port, and is in a natural storage state, and the spare jumper is connected to the first port. After connecting to the second port, it becomes a connection jumper, and the connection jumper is in a non-tight state, that is, the cable connected to the jumper is not subject to any tension, for example, there is no structure such as a coil spring to pull the connection jumper for a long time. Such a design can ensure the mechanical and optical performance of the connecting jumper, which is conducive to ensuring the quality of each optical path (specifically: ensuring signal transmission performance and reducing insertion loss). Due to the guaranteed mechanical and optical performance of the spare jumper, communication The service is also less prone to the risk of signal interruption or poor signal caused by fiber quality problems. Therefore, the present application is conducive to reducing the risk of optical communication services. Since the jumper storage device is an independent module, it can be installed in the optical fiber distribution equipment by detachable assembly. Users can configure the jumper storage device as needed (according to the demand for spare jumpers). In the case of a small amount, the number of spare jumpers can be smaller. After the spare jumpers in the jumper storage device are used up, the spare jumpers can be supplemented or the jumper storage device can be replaced. A large number of spare jumpers are stored in the storage device, and the volume of the jumper storage device can be designed to be miniaturized, which can not only realize the miniaturization of the optical fiber distribution equipment, but also reduce the cost of the optical fiber distribution equipment.

As shown in Figure 3, the optical fiber distribution equipment also includes an external panel, which is used to provide external ports. It can be understood that a number of external ports are set on the external panel. The external ports may include input ports and output ports. The external ports are used for Connect the terminal equipment and the external network, specifically, connect between the terminal equipment and the external port, and between the external network and the external port through cables, whereby the optical fiber distribution equipment can realize the connection between different terminal equipment or sites. optical communication between terminals, or realize optical communication between terminal equipment and external networks. Specifically, the external panel may be arranged in the wiring area, and the external port on the external panel and the first port (or the second port) in the wiring area may be integrated on one panel. The external panel can also be outside the wiring area, and the signal at the first port or the second port can be guided to the external port on the external panel through a cable.
