Research on the Long-distance Transmission

In view of the imbalanced distribution of power load and resources, including the status of “electric shortage” in some cities in our country, the article discusses the long-distance transmission technology. It mainly analyzed two ways of the long-distance transmission: UHV AC transmission and UHV DC transmission. The fractional frequency transmission technology and half wavelength AC transmiss...

The Research of Long-Distance Data Transmission Based on Meteorological Sensor Network

Wireless sensor networks (WSNs) has gained more and more popularity in the field of intensive meteorological observation. Generally, each existing sensor node is a constrained device with restricted computation capability, and limited energy resources. The effective communication range of existing sensor nodes is unable to meet our requirements. In this paper, we present an improved system arch...

Long distance transmission in few-mode fibers.

Using multimode fibers for long-haul transmission is proposed and demonstrated experimentally. In particular few-mode fibers (FMFs) are demonstrated as a good compromise since they are sufficiently resistant to mode coupling compared to standard multimode fibers but they still can have large core diameters compared to single-mode fibers. As a result these fibers can have significantly less nonl...
