This essay designed a kind of new seven-core fiber with lower crosstalk and loss, and made space division multiplexing transmission experiment based on this seven-core fiber. It is known that crosstalk has the most serious influence in multicore fiber transmission process. Before the experiment, the affecting factors of fiber crosstalk were analyzed through simulation, such as core space, bending...
We numerically simulate the influence of mode coupling and modal delay on the transmitted signal. Then we carry out adaptive signal processing with MIMO equalizers based on recursive least squares constant modulus algorithm (RLSCMA). The simulation results show that the distorted signals are restored efficiently with fast convergence speed.
To improve the capability and detection precision of the Fiber Bragg sensing system, the novel interrogation technique and detection algorithm based on the tunable ring laser and multiplexing technology are proposed for the multi-channel Fiber Bragg grating sensing system, which can realize the real-time monitoring of 32 channels more than 1,000 FBG sensors. Here, we use the comb filter as multi-wavelength...
We propose and experimentally demonstrate a novel MAMSK-OFDM-PON. 5-Gb/s MAMSK-OFDM signal and 2.5-Gb/s upstream OOK signal is transmitted over 20km fiber successfully. The results show the prospect of this technology in future optical access networks.
