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

2.1 Introduction. The measurement of the RI. of liquids is a significant work in science and engineering.. Transmission or reflection disclosures near critical angles linked to TIR. are common ways in RI. measurements. Modified Abbe refractometers and commercial Abbe refractometers are instruments for measuring the RI. of a sample using those ways. The RI. resolution of those instruments. roughly extent from 10−4 to 10−5 depending on their cost and complexity. RI. of muddy colloidal

Leonardo da Vinci‚ Michelangelo‚ and Raphael are three of the greatest artists in the art world history. They were extraordinary people with great ideas and visions that eventually reached far beyond the art world alone. These men were known as bitter rivals who were always competing for both commission and fame. Leonardo was the first artist. He made creative works of art that were a reflection of all the unique features of the Renaissance era. He created a new art and an attitude towards the reality
