With the application of electrical equipment, magnetically coupled resonant (MCR) wireless power transfer (WPT) technology has become an effective means to improve equipment intelligence. The MCR‐WPT system is a loosely coupled system, and the resonant frequency may be split or detuned due to the changes of load or transferring distance, resulting in the system transfer efficiency (TE) greatly reduced...
The growing data traffic in the local area networks (LAN) is driving development of the cost-effective transmission systems. In this paper, we investigate the influence of a semiconductor optical amplifier (SOA) on the transmission system of 60 km standard single-mode fiber (SSMF) in the 1310 nm wavelength-division-multiplexed (WDM) system. We investigate the SOA performance and analyze the receiver...
This paper reports a 400-km ultra-long haul unrepealed transmission system in a 8×10 Gbit/s optical transmission network (OTN) by using forward Raman amplifier and backward second order remotely optical pumped amplifier(ROPA). A second order ROPA is obtained by adding an auxiliary second order pump to the first order ROPA. Through experiment, we compare the performance of 1st ROPA and 2nd ROPA in...
Uncertain data may exist in many application fields, due to the inaccurate raw data, the use of coarse-grained data set, for the purposes of privacy protection, and the data integration etc. The original features of the data may be changed or ignored if the uncertainties were mishandled. Therefore the effective management and analysis of uncertain objects should rely on an appropriate uncertain data...
In this paper, a novel Receiver-Transmitter Erbium doped fiber amplifier (RT-EDFA) is proposed and developed, which can realize wavelength conversion and suppress Stimulated Brillouin Scattering (SBS) signals induced by the high power optical signal transmitted along a long-haul optical fiber link. We demonstrate experimentally the SBS suppression function of the RT-EDFA used in 10Gbit/s and 2.5Gbit/s...
This paper reports a 325-km ultra-long span repeater-less transmission system in a 17×10 Gbit/s optical transmission system by using different amplification schemes. We demonstrate two different amplification schemes which combine Erbium doped fiber amplifier (EDFA), Raman amplifier or combined EDFA and remotely pumped optical amplifier (ROPA). The amplification schemes are tested and compared, and...
