According to the method, the whole path from a local terminal to a user terminal is an optical path, and the optical signals can be directly transmitted to the user terminal, thereby greatly increasing the service band width of a user and making full use of the performance of the optical network system.
Description
Technical field
The present invention relates to optical transport technology, specifically, relate to a kind of method that light signal directly is transferred to the user.
Background technology
A typical optical network system mainly is made up of OLT (optical line terminal), ODN (optical distribution network) and ONU (optical network unit).OLT is positioned at local side, is main control centre, realizes the function of network management; ODN provides transmission medium for OLT is connected with data between the ONU, comprising optical cable and various optic components etc.; ONU is positioned at user side, is used for access user terminal.To do a summary to existing EPON know-why below.
Fig. 1 shows the network configuration of FTTB (Fiber to The Building, Fiber-To-The-Building)+LAN (Local Area Network, local area network (LAN)).In the machine room of operator, by correlation technique, miscellaneous service is fused among the OLT, as the CATV business of wired TV, network TV IPTV, Plain Old Telephone Service PSTN, network service etc.Signal carries out the signal transmission from the OLT of local side through the optical fiber backbone network, arrives ONU by ODN (optical distribution network there is shown the optical branching device in the optical distribution network), and ONU gives different users with signal.
Fig. 2 shows the network configuration of FTTN (Fiber to The Node, Fiber-To-The-Node)/FTTB+DSL " reconstruction of the old city town ".The network configuration form of FTTN/FTTB+DSL and FTTB+LAN is more approaching." reconstruction of the old city town " takes into account the existing network line of incoming end, is the solution that a kind of optical-fiber network that can effectively reduce the up-front investment cost is transformed.
Fig. 3 shows the network configuration of FTTH (Fiber To The Home, Fiber to the home).Fibre faceplate has been linked into the family parlor.And between fibre faceplate and ONU, normally adopting passive SC wire jumper to be connected, ONU separates signal respectively by a series of data, protocol conversion function according to different demands, use for different household equipments.
The use of optical network system, the copper cash that has reduced significantly in the signal transmission uses, and make efficiency of transmission be greatly improved, yet it still has many improvements.For example, for ONU, existing ONU has following some shortcoming:
(1) small product size is excessive, takies user's space.
(2) may cause the wasting of resources.Most user only uses wherein one or more business, and other untapped functions will cause waste.
(3) product cost is higher.Because of built-in various functional chips and numerous structural members, cause cost not low.
(4) fail to avoid fully the use of copper cash.Between from ONU to the subscriber equipment, still need to utilize copper cash to carry out the signal transmission, although this segment distance is limited, yet the copper cash of this final stage uses the main bottleneck that exactly becomes restriction optical network system performance, has significantly restricted user's service bandwidth.
Summary of the invention
The main technical problem to be solved in the present invention is, provides a kind of light signal directly is transferred to the method for subscriber equipment, and the performance that it can give full play of optical network system, the restriction that makes optical transmission not used by copper cash improves user's service bandwidth.
For solving the problems of the technologies described above, the present invention has adopted following technical scheme:
A kind of light signal directly is transferred to the method for subscriber equipment, comprises:
