AWG is Arrayed Waveguide Grating and is the technology of first choice in dense wavelength division multiplexing systems (DWDM). AWG is a planar waveguide device, which is an arrayed waveguide grating

Why is AWG demanded? As we know, DWDM technology enables transmission of dozens of wavelengths in a single fiber, which expands the capacity of optical fiber communication enormously. The first mux/demux

가전제품은 작당하지 않고서야 좀처럼 전선이 피복 안쪽에서는 끊어지는 일이 없습니다. 집에서 만드는 소소한 장난감도 전선은 잘 보이지 않는데다 흐르는 전류도 낮아서 끊어지는 일은 드물죠. 그런데 드론에서는 종종 생깁니다. 가는 전선을 모아 꼬아둔 구조는 반복해서 구부리다 보면 비슷한 시기에 피로 강도가 떨어져 끊어지기도 하고 높은 전류를 사용하기 때문에 전선의

vfinally @ecoloBlue on @UnboxTherapy ! WOW alex jones has been selling the EcoloBlue machine for years! It creates pure water out of thin air just using electricity! (totally solar ready!) They start at

The people in Flint, Michigan need clean water. They are so desperate, people are using bottled water to shower with, wash their clothes, cook with, etc. Rather than deliver truck loads of bottled water,
