[Abstract]:With the rapid expansion of multimedia and data applications, the bandwidth demand of the backbone network is growing at an unprecedented rate. The increase of backbone capacity also brings more challenges to the bandwidth and interconnection of data centers. At present, fiber manufacturers are constantly improving the performance of optical fiber to meet the needs of long-distance and short-range applications. Although the system capacity can be increased by improving the traditional optical fiber technology in the short term, the research shows that the transmission capacity of single-mode fiber is fast approaching the Shannon theoretical limit. This limitation can be overcome by using space division multiplexing (SDR) technology, which can provide a new solution for future capacity growth. In this paper, a new type of fiber is discussed to improve the capacity of optical fiber transmission system. For conventional optical fibers used in long-distance transmission, advanced digital signal processing can completely compensate for the damage such as dispersion and polarization mode dispersion, so the attenuation and effective area of the fiber become parameters that can be further optimized. The quality factors of these two parameters are discussed, and the latest research results of ultra-low loss and large effective area fiber are summarized. For short range applications, the methods to improve the bandwidth of multimode fiber are reviewed, and the development trend of multimode fiber is discussed. For the next generation fiber, we focus on multi-core and low-mode optical fiber which can realize space-division multiplexing technology, which can increase the system capacity by an order of magnitude. This paper describes the design ideas of multi-core and low-mode optical fibers, summarizes the latest development of the technology, and finally discusses the main challenges facing the use of multi-core and low-mode optical fibers.
