Detailed Description

The embodiments of the present invention will be described below with reference to the drawings.

The optical fiber distribution equipment is applied to optical network technology. Optical network technology refers to network fabric technology that uses optical fiber transmission. The optical network technology is not only a simple optical fiber transmission link, but also realizes interconnection and flexible scheduling of a multi-node network by utilizing optical and electronic control technologies on the basis of a large-capacity, long-distance and high-reliability transmission medium provided by optical fibers. Optical networks generally refer to wide area networks, metropolitan area networks, or newly created large area local area networks that use optical fibers as the primary transmission medium.

An Optical Network or an Optical fiber scheduling system provided in an embodiment of the present application is an ODN (Optical Distribution Network). The ODN is a Fiber-To-The-Home (FTTH) cable Network based on a PON (Passive Optical Network, J) device, and functions To provide an Optical transmission channel between an OLT (Optical Line Terminal) and an ONU (Optical Network Unit). Functionally, the ODN can be divided into four parts, i.e., a feeder cable subsystem, a distribution cable subsystem, a service line cable subsystem, and an optical fiber terminal subsystem, from the local side to the subscriber side.

In one possible implementation manner, the jumper recovery device is directly installed inside the optical fiber distribution equipment, and the jumper recovery device is fixedly connected with a frame body (or a shell or a frame) of the optical fiber distribution equipment. In this embodiment, the recovery area is an area where the jumper recovery device is installed.

A plug-in device is understood to mean an automated transport and handling device provided with a gripper (or a robot arm, or a robot). The plug-in device can move between the wiring area and the storage area and/or between the wiring area and the recovery area. The plugging device can execute plugging action in the wiring area, fiber taking action in the storage area (namely, taking out the standby jumper from the jumper storage device), and recovery abandoning jumper action in the recovery area. The plugging device can take out the standby jumper from the jumper storage device and insert two connectors of the standby jumper into the corresponding first port and the second port respectively to realize an optical access; and/or the two connectors of the connecting jumper are respectively pulled out from the corresponding first port and the second port, the pulled-out connecting jumper is the abandoned jumper, and the plugging device is used for conveying the abandoned jumper to the jumper recovery device.

In a conventional optical fiber distribution facility, two distribution panels (or two distribution areas on one panel) are included, wherein one distribution panel (or distribution area) is used for arranging connectors (plugs for inserting optical fiber adapters), each connector is connected with an optical fiber (also called a pigtail), and it can be understood that the distribution panel is used for connecting a large number of optical fibers, which are all multiplexed optical fibers, that is, one optical fiber needs to be repeatedly used to perform different service requirements. When a certain optical fiber is needed to communicate with a certain optical path, the optical fiber needs to be pulled out from one distribution panel by a robot arm, transported to another distribution panel, and inserted into an adapter port of another distribution panel. When it is desired to disconnect an optical path, the corresponding fiber is retracted, i.e., its connector is pulled from the adapter port and returned to its original position. Under the structure, the optical fiber distribution equipment needs a larger space to store the optical fiber, so that the cost is high and the volume is huge. Moreover, each optical fiber needs to be managed orderly, and is in a straightening state in the storage space, the optical fiber is in a stretched state for a long time, and in the process of inserting and taking up the wire, the service life of the optical fiber is reduced due to the fact that the optical fiber is pulled back and forth, and risks such as signal interruption or badness are formed for optical communication services.

The application provides an optic fibre distribution equipment is consumptive material formula distribution equipment, takes out reserve jumper wire from the jumper wire storage device through the plug module, and this reserve jumper wire uses as disposable consumptive material, and the plug module is connected reserve jumper wire in order to realize the light path of the business port that corresponds between first port and the second port. The standby jumper is a disposable consumable material, is stored in the jumper storage device before being connected to the first port and the second port and is in a naturally placed storage state, and is changed into the connection jumper after being connected to the first port and the second port, and the connection jumper is in a non-tensioned state, namely a cable for connecting the jumper is not subjected to any tension force, for example, the connection jumper is pulled for a long time without structures such as coil springs. The design can ensure the mechanical and optical performance of the connecting jumper, is favorable for ensuring the quality of each optical path (particularly ensuring the signal transmission performance and reducing the insertion loss), and because the mechanical and optical performance of the standby jumper is ensured, the communication service is not easy to have the risk of signal interruption or poor signals caused by the quality problem of optical fibers, thereby being favorable for reducing the risk of the optical communication service. Because the jumper wire storage device is an independent module, the jumper wire storage device can be installed in the optical fiber distribution equipment in a detachable assembly mode, a user can configure the jumper wire storage device as required (according to the demand of the standby jumper wires), when the demand is less, the quantity of the standby jumper wires can be smaller, after the standby jumper wires in the jumper wire storage device are used up, the standby jumper wires can be supplemented or replaced, a large number of standby jumper wires do not need to be stored in the jumper wire storage device, the size of the jumper wire storage device can be designed to be small, the miniaturization of the optical fiber distribution equipment can be realized, and the cost of the optical fiber distribution equipment can be reduced.

Specifically, the circumscribed panel may be provided at the wiring region, and the circumscribed port on the circumscribed panel and the first port (or the second port) in the wiring region may be integrated on one panel. The external panel can also be outside the wiring area, and can guide the signal at the first port or the second port to the external port on the external panel through the cable.

second claws

26211 and 26212 are located on opposite sides of the connector, respectively, and at this time, the first and

second claws

26211 and 26212 are moved relatively close to each other and clamp the connector by driving the clamping drive motor 2672. The traversing motor 2682 is driven to drive the connectors carried by the first claws 26211 and the second claws 26212 to move to the crawling area 105, so that the connectors are kept away from other connectors on the wiring panel, and the connectors can be conveniently conveyed to the jumper wire recovery device 400.

Of course, four driving wheels may be provided, and it is understood that two third driving wheels are provided in the bottom area S4, and the size of the conveying path of the conveyor belt 423 may be adjusted to match different application requirements by increasing the number of the driving wheels. For example, when the size of the spare patch cord is long, the conveying path of the conveyor belt can be extended in a limited space by increasing the number of the driving wheels to match the long size of the spare patch cord, so as to smoothly bring the spare patch cord into the recovery box 41.

The discharge area S6 is adjacent to the first end 4201, and the take-out area S7 is located at the top area S5 and adjacent to the second end 4202. When the connectors discarding the jumper wires are carried to the position of the material taking section S7 by the conveyor belt 423, the plugging device 200 removes the fixed relationship between the connectors discarding the jumper wires and the conveyor belt, and then the discarding jumper wires fall into the recovery box 41 by gravity by the reverse movement of the conveyor belt 423.

In this embodiment, the plugging device 200 moves in the direction perpendicular to the first baffle 421, so that the plugging device 200 operates the connector for discarding the jumper wire in the material placing region S6 and the material taking region S7. Specifically, the first baffle 421 is provided with a discharging port 4214 and a material taking port 4215, the discharging port 4214 is located in the discharging area S6, and the material taking port 4215 is located in the material taking area S7.
