Application details of the cable router

With the rapid development of a router, a variety of technology has also gone, now it is mainstream cable router as one of the technologies, their application is very broad, so I've done some research in the use of fiber optic cable router needs special attention details out here and share with you, hope to be useful.
As part of a passive FTTH networks, FTTH cable although no active part of the concern, but the ODN architecture design and selection of cable router for FTTH project and still have a significant impact network quality. In the FTTH network, the cable router product selection, depends primarily on the ODN network architecture planning. In other words, the OLT from the central office to the client of the ONU, which should be divided into several sections. In determining the starting position of each paragraph, in accordance with the paragraph on the cable router products in the laying environment, construction efficiency and wiring facilities of the specific requirements in order to make more appropriate choices.

Distribution network planning point of light is key

For the ODN network architecture, planning, depends on three basic elements, that is, setting the OLT, ONU distribution program set up and light settings. Among them, the light distribution program set up for the greatest impact on the entire network infrastructure, because the light distribution points by way of multi-level splitting set anywhere in the ODN network. In the United States and Japan, are two commonly used way of splitting it with the residential characteristics of the two countries, labor costs, network construction mode and other factors are closely related. In China, telecommunications operators, network construction, usually in the form of coverage for the community. Therefore, the actual user community the opening rate of return on investment of the project is relatively large. With reference to the use of two foreign or multi-level splitting of the spectral method, the user is not bound to have open central office OLT and the optical splitter generates invalid occupation, making the burden of heavy upfront investment. It would also make the network more complex, increasing the construction, management, maintenance of the difficulty and cost.

After years of practice and exploration, the domestic telecom operators has been basically established a relatively consistent with China's FTTH network construction program, the ODN network construction identified the following guidance: in a certain coverage, OLT as set the existing end office room, the centralized management; ONU should be set in the user home, using local power supply; maximize the use of a spectrophotometric method, centrally located, and as close to the user. The greatest feature of this program is open according to the user's actual rate, reasonable control and splitter in PON equipment investment. And, because the network structure is simple, the network reliability can be improved, but also greatly improve the construction, management and maintenance efficiency.
