To best describe DWDM (coarse wavelength division multiplexing) and DWDM (dense wavelength division multiplexing)‚ you must first understand how WDM (wavelength division multiplexing) operates. WDM is multiplexing several optical signals on a single fibre by using wavelengths which are essentially colours of the laser light; to transmit different signals ranging from 2.5Gbps to 40Gbps. The device that connects the signals together is a multiplexor‚ and the one that splits them apart on the other

------------------------------------------------- Refractive index From Wikipedia‚ the free encyclopedia In optics the refractive index (or index of refraction) n of a substance (optical medium) is a dimensionless number that describes how light‚ or any other radiation‚ propagates through that medium. Its most elementary occurrence (and historically the first one) is in Snell’s law of refraction‚ n1sinθ1= n2sinθ2‚ where θ1 and θ2 are the angles of incidence of a ray crossing the interface between

for as long as I like. I took photographs extensively when I travelled in China‚ and later in my first year of college. My interests intensified and went beyond just apparent forms‚ when during my first summer in college I read about linear and nonlinear dynamics‚ emergence behavior‚ game theory‚ neuroscience and spatio-temporal pattern formation in books intended for undergraduate students or the general public. I decided that my appreciation for nature would only deepen and advance if I learned
