Description
Technical field
The embodiment of the invention relates to the optical communication technique field, particularly a kind of service data transmission method and device.
Background technology
Along with the decline of traditional voice income and the aggravation of competition, by the business model of voice, video and data " unification of three nets " being supported income, this tie-in mode needs access device that bigger bandwidth, lower cost of investment (CapEx) and operation cost (OPEX) can be provided in telecom operators.
At present, SDH (Synchronous Digital Hierarchy) (Synchronous Digital Hierarchy, hereinafter to be referred as SDH), Synchronous Optical Network (Synchronous Optical Network, hereinafter to be referred as: SONET), optical transfer network (Optical Transport Network, hereinafter to be referred as: OTN), bag transmits network (PacketTransport Network, hereinafter to be referred as: PTN) be mature technology in the transmission field, obtained using widely.
In existing Access Network field many implementations are arranged also, for example: digital subscriber line xDSL, active point-to-point, EPON (Passive Optical Network, hereinafter to be referred as: PON), technology such as wireless access.Wherein the ADSL technical costs is lower, but limited bandwidth; The VDSL bandwidth can reach more than the 50M, but transmission range is shorter; Digital subscriber line xDSL is based on the technology of copper cash, have antijamming capability a little less than, the shortcoming that bandwidth is lower, and along with copper in short supply as strategic resource, its development also is restricted.
Fig. 1 is an optical-fiber network schematic diagram in the prior art, as shown in Figure 1, PON is as a kind of broadband light access network technology, be characterized in a little arriving the physical topological structure of multiple spot, PON is by optical line terminal (Optical LineTerminal, hereinafter to be referred as: OLT), passive optical distribution network (Optical DistributionNetwork, hereinafter to be referred as: ODN), a plurality of optical network unit (Optical Network Unit, hereinafter to be referred as: ONU) form; A plurality of ONU share fiber resource and OLT port; Optical branch point among the ODN does not need active node device, only need passive optical branching device, therefore PON has that machine room investment, device security height are shared, saved to bandwidth resources, fast, the comprehensive networking cost of networking speed is low and advantage such as operation maintenance cost is low, is the ideal solution of " last kilometer ".These advantages make the application of PON increase sharply, and become the main means of FTTx.FTTx comprises that Fiber To The Building (Fiber To The Building, hereinafter to be referred as: FTTB), Fiber To The Curb (Fiber To The Curb, hereinafter to be referred as: FTTC), Fiber To The Equipment (Fiber To The Equipment, hereinafter to be referred as: FTTE), Fiber to the home (FiberTo The Home, hereinafter to be referred as: FTTH), FTTC (Fiber To The Neighborhood, hereinafter to be referred as: FTTN), fiber-to-the-subscriber (Fiber To The User, hereinafter to be referred as: FTTU).
