| Abstract: | Operator''s network bandwidth expansion by light transmission in DWDM technology, not only greatly using the limited and expensive cable resources, and increase the utilization rate of the bandwidth of optical fiber, but also reduce the maintenance and construction cost of the whole system. Of the DWDM equipment in the network in the practical application of bearing is described in detail firstly the DWDM technology were detailed introduction; and then through analysis of Dazhou CATV business network bandwidth demand, combined with the actual situation of tailored as the construction scheme of the state radio and television networks; also of Dazhou broadcasting of the OTN network DWDM equipment application is analyzed, from the network planning, the facility determines, equipment installation and commissioning, carrying business. |
