More than 100Gbps Fiber Transmission Technology Information

    With the continued popularity of large numbers of fixed broadband access users and future deployment of LTE mobile networks and various broadband applications, fiber optic backbone transmission network bandwidth demand will continue to grow rapidly. According to data Optical Internetworking Forum (OIF) announced, the commercial network operators long-term average annual traffic growth will exceed 50%, or less than 2 years traffic has doubled; the data from the China Telecom is to increase the transmission capacity of close to 100% per year, five-year increase 10-20 times the bandwidth. In the fiber bandwidth demand driven by rapid growth, N × 100Gbps DWDM optical transport began to move toward large-scale commercial, while the next-generation DWDM technology that is a single-channel ultra 100Gbps optical transmission technology research has started


The called "super 100Gbps DWDM system" generally refers to a single wavelength channel rate of 400Gbps or 1Tbps, and spectral efficiency is greater than the current mainstream of N × 100Gbps DWDM of 2bit / s / Hz high-capacity WDM systems. Super 100Gbps system single-channel and customer-side interface rates are mainly two kinds: 100Gbps or 1Tbps, the rate of evolution of the law by IP community 1Tbps is an option, but the difficulty of the integrated technology, 400Gbps is another possible option. Nearly for two to three years the world's leading research institutions and well-known optical communications equipment manufacturers in over 100Gbps technically actively carry out more in-depth study,  and  has completed a number of future super 100Gbps technology to influential system test.
