A challenge is to measure the impairments of few-mode fiber (FMF) for mode division multiplexing (MDM) system, so as to quantify the few-mode fiber and compensate the impairments, and thus improves the transmission performance of MDM system. In this paper, the experimental setup of impairments measurement with the structure of Photonic Lantern and optical circulators is established. Not only the two...
We make some measurement research based on CW SPM method, and obtain the non-linear coefficient for the novel ultra low loss& large effective area single mode fiber. And we also discussed the measure uncertainty and non-linear coefficient influence factor.
We demonstrate the fabrication of long-period fiber gratings written in six-mode fiber by CO2-laser pulses as a mode converter to realize the mode conversion from LP01 mode to LP11 mode, LP21 mode and LP02 mode successfully with efficiencies of more than 90%, respectively.
At present, the power communication network has many evaluation indexes, but the existing OTN operation risk evaluation index is only a simple statistical index, and lack of analysis and evaluation and prediction of indicators. It is more important to optimize the software defined-optical transmission network (SD-OTN) performance and improve the network bandwidth. In order to explore the auxiliary...
In this paper, service risk model based on the fiber link failure is defined for the power communication over optical transport networks (OTN). We also propose the computation methods for the probability of fiber link failure, and the service losses. The methodfor service risk analysis is designed and the probability of fiber link failure is analyzed. The reliability loss caused by the single fiber...
Weakly-coupled mode-division-multiplexing (MDM) is a promising approach to overcome the capacity crunch in optical transmission systems and networks. In this paper, we present the latest progresses of weakly-coupled MDM transmission over multi-mode fiber (MMF) or few-mode fiber (FMF) supporting large quantity of independent modes with intensity modulation and direct detection.
