specific Embodiment 1

[0070] Such as figure 1 As shown, the hierarchical structure of the FTTdp-based fiber broadband access model in the present invention includes: OLT (optical line terminal, optical line terminal), DPU and VDSL equipment.

[0071] The OLT includes a main control panel and a line card. The main control panel is used to connect to other platforms upwards and manage the line cards downward; the line card is connected to the main control panel upwards to manage the ONU (optical network unit, optical network unit) and DPU downward.

[0072] The DPU connects to the connection card upwards and manages the VDSL equipment downwards. The DPU is similar to optical splitting. It has multiple VDSL interfaces and can be connected to one or more VDSL equipments. Usually, it can be connected to 8 VDSL equipments.

[0073] VDSL equipment is the user's home equipment, and each VDSL equipment corresponds to a user. The service activation is based on the VDSL equipment, and the VDSL equipment accou...

specific Embodiment 2

[0081] In the specific embodiment 2 of the present invention, the service provisioning process of the VDSL device only includes the account input of the VDSL device, and the DPU itself does not have any additional actions during the provisioning process, and the self-registration process is automatically completed, and the system will not allocate additional resources to the DPU for registration.

[0082] Such as image 3 , Figure 4 As shown, the specific steps for the DPU to automatically complete the registration with the OLT are as follows:

[0083] Step 211: DPU accesses OLT;

[0084] Step 212: When the OLT obtains the device information, it reports information according to the capability of the ONU to know whether the connected ONU is a DPU device, and if it is a DPU device, step 213 is performed; otherwise, the normal optical modem registration process is performed;

[0085] Step 213: the line card reports the device information of the DPU to the main control panel; ...

specific Embodiment 3

[0101] Specific embodiment 3 of the present invention has provided the method for realizing VDSL equipment speed limit by DPU, and concrete method is as follows:

[0102] Configure the rate limit data of the VDSL device on the ITMS and send it to the DPU through the OLT. The configured speed limit data includes the network speed of the desired limited VDSL device and the VDSL interface of the DPU bound to the VDSL device;

[0103] After the DPU receives the speed limit data sent by the OLT, it binds the limited network speed value to the VDSL interface corresponding to the DPU.

[0104] During use, the DPU controls the rate of the VDSL device through the limited network speed configured on the VDSL interface.

[0105] Through the above method, it is possible to limit the network speed of different users, increase the types of services, and meet the needs of different users. For example: on the premise of not changing the hardware, it can provide broadband services of differe...

Abstract

The invention discloses an optical fiber broadband access system based on FTTdp mode and its implementation method. The method includes: VDSL equipment connects optical fiber through DPU; The multi-channel copper cable data transmitted by the copper cable is sent from the corresponding VDSL interface of the DPU to the VDSL device according to the VDSL interface bound to the account of the VDSL device; in the uplink direction, the DPU maps the copper cable data transmitted by each VDSL device into The optical fiber data is aggregated and sent to the OLT through the optical fiber. In the present invention, the data signal is switched back and forth between the optical fiber data and the copper cable data through the DPU, which not only achieves the correctness of the upwardly converged data signal, but also ensures the correctness of the downward distribution of the data signal, ensuring the copper cable to enter the home. Users can enjoy the high-speed network of optical fibers when using VDSL equipment.

Description

technical field [0001] The present invention relates to the field of FTTdp (Fiber to the Distribution Point, fiber to distribution point) fiber optic broadband access, in particular to an FTTdp-based fiber optic broadband access system and an implementation method thereof. Background technique [0002] With the rapid development of the Internet, people's requirements for accessing the Internet are getting higher and higher. Regardless of construction cost, or transmission speed and capacity, compared with ADSL, optical fiber transmission technology has obvious advantages. Therefore, "light advances copper and retreats" has become the general trend of communication network development in recent years. [0003] Although, FTTH (Fiber to the Home, fiber to the home) is the most ideal broadband access mode with the most development potential. However, due to the high cost of fiber-to-the-home projects, especially for some old buildings, the construction of fiber-to-the-home is ...
