Professional provider of high-end integrated DWDM solutions for big data transmission

  DWDM is often used by telecommunications, cable and data centers as part of their optical transport network.   Carrier Transport Network The carrier transport network is made up of several layers of aggregation called the access network, metro aggregation network, edge network and the core backbone network. DWDM is most often used in the metro aggregation network and the core backbone network.   DWDM in the metro aggregation network is used to combine data from several cities. As service providers bring more computing capabilities closer to their customers, DWDM is also flexible enough to meet their needs for higher bandwidth aggregation as they begin to converge more data into a single node to compute. The core backbone often deals with the high-speed switching of large amounts of data between their major central offices, which can span across several regions, states or even countries, which is also ideal for using DWDM.   If need more information, welcome ...

  WDM technology has many advantages and is developing rapidly. Main features include: 1) The bandwidth resources of the optical fiber can be used to increase the transmission capacity of an optical fiber several times to several tens of times compared with single-wavelength transmission; 2) multi-wavelength multiplexing in single-mode optical fiber transmission can save a lot of optical fiber during large-capacity long-distance transmission; 3) The installed cable has a small number of cores, and the wavelength division multiplexing can be used to expand the capacity without major changes to the original system; 4) since the wavelengths of the signals transmitted in the same fiber are independent of each other, signals with completely different characteristics can be transmitted. 5) T he wavelength division multiplexing channel is transparent to the data format, that is, it has nothing to do with the signal rate and electrical modulation mode. 6) A WDM system can carry multiple fo...
