10 m - 20 m bandwidth to the home is to meet the initial development of triple play, the medium term need 30 - 50 m, long-term development needs more than 100 m..
The core function of OLT
Include aggregate distribution and service processing function as well as ODN adaptation functions. The aggregation distribution and service processing functions process the information of different services, including multiplexing / demultiplexing, switching / interleaving, service quality control, bandwidth management, user isolation, broadcasting and multicast, etc., the uplink is connected with the service interface function, and the downlink is connected with the ODN adaptation function. Wherein the multiplexing / demultiplexing function is used for providing a uniformly multiplexed information transmission channel for transmitting and receiving various service flows in the ODN direction, and the switching / interleaving function is used for providing switching / interleaving capability for bandwidth available at the ODN side of the OLT and bandwidth available at the OLT network side; The service quality control function refers to the control function of OLT resources and related service flows required to ensure the QoS, security and other characteristics of various services in the OLT service processing process; User isolation and business isolation function is based on the user or business type of traffic isolation measures taken to prevent the user data privacy is damaged and business stolen; Broadcast and multicast function refers to the OLT node to achieve point-to-multipoint traffic transmission should support the broadcast and multicast capabilities, in order to improve the efficiency of bandwidth use.
Odn
The optical distribution network provides one or more optical transmission channels between one OLT and one or more ONU, divided into upstream and downstream directions. In the downstream direction, the OLT transmits the service from the service node interface to all ONU connected thereto by ODN broadcast. In the upstream direction, the system adopts time division multiple access technology to make ONU transmit information without collision to OLT.
Onu
The role of ONU is to provide direct or remote user interface for optical access network, to reuse and demultiplex the different services of the corresponding user ( uplink direction will be different home terminal different service signals multiplexed together, in the same transmission channel transmission; The downstream direction demultiplexes different services and sends the services to the corresponding terminals through different interfaces ), and is positioned at the user side of the ODN. An ONU can connect a plurality of users, and the ONU terminates the information from the ODN, processes the optical signal and provides a service interface for a plurality of users. The network side is an optical interface and the user side is an electrical interface, so that the optical / electrical and electrical / optical conversion functions are provided. Onu also completes the digital / analog and analog / digital conversion, signal processing, multiplexing and maintenance management functions of voice signals.
In practical application, FTTH is based on pon networking scheme
1 ) with primary light splitting is given priority to, secondary light splitting is auxiliary.
2 ) pon port branch ratio is given priority to with 1: 64, individual is 1: 32.
3 ) optical splitter is given priority to with centralized placement, decentralized placement as auxiliary.
4 ) the corridor to the user's family commonly used butterfly leather cable. The quantities of the new building leather line cable layout reflected in the design; Reconstruction area of leather cable layout of quantities shall be borne by the operation and maintenance.
5 ) the client uses a home sfu terminal or a home gateway ( hgu ) based on pon uplink. General design does not carry out investment budget, provided by the operation and maintenance and installation.
Ftth access is all-optical network access, network structure evolved into four nodes a terminal.
Four nodes: integrated service convergence node ( OLT node ), backbone fiber distribution point, wiring fiber distribution point, building / floor fiber distribution point.
One terminal: the user-side home ONU or home gateway.
Ftth access adopts a first-level splitting mode, and the splitter is installed in the wiring optical intersection; Wiring light intersection installation location: high-rise building ( more than 64 households ), 1 building is provided with 1 wiring light intersection, installed in the access room / shaft; Multi - storey building will be more than one unit building as a wiring area, wiring area user capacity is not less than 64 households, the whole community should try to reduce the number of wiring area, high-rise building every 3 - 4 layer ( 12 - 24 ) set up a floor fiber box, wiring light cross installed in indoor stair / outdoor, stair is given priority to.
Each unit of the multi-storey building is provided with one building fiber box.
Trunk optical fiber - distribution optical fiber - building / floor fiber box connection cable selection of ordinary optical cable; Building / floor fiber box - the user selects the leather cable for connection.
The first-level light splitting is mainly used for the construction mode of new buildings.
Ftth access adopts a two-stage splitting mode, the first-stage splitter is installed in the distribution optical crossover, and the second-stage splitter is installed in the building / floor shunt box. Wiring light intersection installation location: high-rise building ( more than 64 households ), 1 building is provided with 1 wiring light intersection, installed in the access room / shaft; Multi - storey building will be more than one unit building as a wiring area, wiring area user capacity is not less than 64 households, the whole community should try to reduce the number of wiring area, wiring light cross installed in the indoor stair / outdoor, stair is given priority to.
High - rise building every 3 - 4 layer ( 12 - 24 households ) set up a floor shunt box, multilayer building each unit set up a building shunt box.
Trunk optical fiber - distribution optical fiber - building / floor fiber box connection cable selection of ordinary optical cable; Building / floor shunt box - user connection selection of leather cable.
The secondary light splitting is mainly used for the original regional reconstruction and construction mode.
Selection of splitting method: for the newly-built community with signing intention, the capacity problem is mainly solved, the distance of using the incoming layer optical cable is short, the use of large-core optical cable has little influence on the investment, and the first-level splitting is preferred from the viewpoint of high utilization ratio of splitter ports, thereby reducing the occupation of trunk and OLT ports; For thin coverage area, the introduction of optical cable distance is long, large core number of cable use, will lead to greater investment increase angle consideration, should choose the secondary light splitting.
The differential classification of fiber optic transceivers is divided by rate, and currently fiber optic transceivers can be divided into 10 / 100 m adaptive fiber optic transceivers and 10 / 100 / 1000 m adaptive light
Fiber transceivers, pure gigabit fiber transceivers, 10 gigabit fiber transceivers.
Pure gigabit transceiver products work at the physical layer, where the transceiver products work by bit to forward data. This forwarding mode has the advantages of fast forwarding speed, high permeability, low delay and so on. it has good compatibility and stability. it is suitable for the link with fixed rate. The 10 / 100 m fiber optic transceiver and the 10 / 100 / 1000 m fiber optic transceiver operate at the data link layer, where the fiber optic transceiver uses a store-and-forward mechanism that reads its source MAC address and destination MAC address for each packet received and forwards the packet out after the CRC cyclic redundancy check is completed. The advantage of store-and-forward is that it can prevent some erroneous frames from spreading in the network, occupy valuable network resources, and prevent packet loss due to network congestion. When the data link is saturated, store and forward can put the data that can't be forwarded in the transceiver's cache, waiting for the network idle before forwarding. This reduces the possibility of data collision and ensures the reliability of data transmission, so the optical fiber transceiver is suitable for working on links with variable speed, such as security monitoring, network data signal extension, etc. Ten thousand trillion optical fiber transceiver is mainly used in the photoelectric conversion of data room, the relative application in the market at present
Less, only optical technology in China the company has to do ten thousand trillion optical fiber transceiver.
By structure, it can be divided into desk-top ( stand - alone ) fiber-optic transceivers and rack-mounted fiber-optic transceivers.
