Description
The application is application number is 201210113616.0, and the applying date is on 04 18th, 2012, and patent name is the divisional application of small intelligent optical distribution equipment.
Technical field
The present invention relates to optical communication field, particularly relate to a kind of small intelligent optical distribution equipment.
Background technology
Build by FTTH (Fiber-To-The-Home, fiber to the home) and pull, global ODN (Optical Distribution Network, optical distribution network) welcomes explosive growth.Because FTTH mainly adopts PON (Passive Optical Network, EPON) technology, it is by an OLT (Optical Line Terminal, optical line terminal) give tens of up to a hundred ONU (Optical Network Unit along separate routes, optical network unit), this produces the fibre circuit of flood tide with regard to the user side making ODN net, and needs to carry out distribution scheduled maintenance management.
Early stage lightguide cable link is substantially all point to point line, management is relatively easy, be the ODN network of FTTH service be then the circuit of point-to-multipoint, continue to continue to use and the alphanumeric tag of manual identified can only carry out optical fiber distributing management at present, its maintenance workload and management difficulty will significantly rise.Add the EPON characteristic of PON technology one-to-many, this just makes on an optical branch network, and user arbitrarily can be linked on any one branch road and carry out normal Signal transmissions, and is not the perception of network manager institute.This characteristic makes the manageability of ODN decline to a great extent.The leak of labor management will make network data occur not consistent mistake with real network situation, and this will bring a lot of difficulty to follow-up network operation work.For addressing this problem, the electronic label technologies such as eID are there is, the mode utilizing electronics automatically to gather manages optical fiber distributing, to stop the issuable mistake of labor management, and utilize computer networking technology to instruct network operation, thus the port that needs carry out operating can be highlighted out rapidly in thickly dotted Optical Distribution Frame adapter arrays, to reduce labour intensity.
