Accessing device, system and method for fiber network

Abstract

An accessing device, system and method for fiber network are provided. The device includes a line card, a forwarding chip and an uplink plug-in card. The forwarding chip is connected to a service interface of the line card via a first physical bus, and is used for sending service data from the service interface of the line card to a corresponding uplink port in the uplink plug-in card based on corresponding relationship between the MAC address of the service interface and the MAC address of the uplink port; and the uplink plug-in card accesses the fiber network via a second physical bus, and is used for forwarding the service data from the forwarding chip to the fiber network via the uplink port. The forwarding chip can implement different accessing modes via a unified physical bus and by multiplexing physical ports which are needed by different accessing modes, therefore, the development and maintenance cost is reduced, and the accessing flexibility is improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to an access device, system and method for an optical fiber network. Background technique [0002] With the maturity of network service applications, users have higher and higher requirements for bandwidth. Optical fiber instead of cable has become the development trend of access network. The promotion of fiber-to-the-x (FTTx) network construction mode, for example: Fiber To The Cell (FTTC for short), Fiber To The Building (FTTB for short), etc., make the distance between the optical network unit and the user terminal closer and closer, and network operators have to increase Deploy a large number of small and medium-sized optical network units. [0003] In the prior art, for different access methods, the optical network unit uses different forwarding chips to forward the service data received by the line card from the user; for different uplink access modes, d...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, for different access methods, the optical network unit uses different forwarding chips to forward the service data received by the line card from the user; for different uplink access modes, different uplink cards need to be replaced, For example: for a Digital Subscriber Line (DSL) network, the DSL forwarding chip used by the optical network unit will send the service data received through the service interface corresponding to the DSL on the specified line card to the specified uplink access mode. The uplink port in the uplink card; for a local area network (LAN for short), the LAN forwarding chip used by the optical network unit sends the service data received through the service interface corresponding to the LAN on the specified line card to the specified uplink access port. The uplink port in the uplink card corresponding to the corresponding mode, which makes the development and maintenance costs high and lacks access flexibility
